Product Overview The iFJF Lost Motion Assembly (LMA) is a direct replacement for the VTEC rocker arm mechanism in Honda B-series engines — including the legendary B16A, B16B, B18C, B18C1, and B18C5. The LMA is a spring-loaded plunger that maintains tension on the VTEC rocker arms during low-RPM (non-VTEC) operation. When LMAs wear out or seize, you get the dreaded "VTEC tick" — a rhythmic ticking noise from the cylinder head, poor VTEC engagement, and potential rocker arm damage. This kit of 8 LMAs replaces all units in a single cylinder head. Key Features Complete Set of 8: One head requires 8 LMAs — this set provides everything needed for a full replacement. No need to piece together individual units. OEM-Grade Spring Tension: Precision-calibrated internal springs match factory spring rates for correct VTEC rocker preload and smooth engagement/disengagement. Eliminates VTEC Tick: Collapsed or seized LMAs are the #1 cause of rhythmic cylinder head ticking at idle and low RPM. New LMAs restore quiet operation. B-Series Specific: Engineered for B16 and B18 VTEC cylinder heads. Inspect the tip condition and overall length to verify compatibility before installation. Restores Lost Power: Worn LMAs cause incomplete VTEC lobe engagement — you lose the high-RPM power bump that makes VTEC engines special.

This is an advanced engine-internal job. The camshafts must be removed in the correct sequence to avoid warping. Use assembly lube on the LMA bores and soak new LMAs in engine oil before installation. Always replace the valve cover gasket and cam seals while you're in there. After installation, bleed the LMAs by letting the engine idle for 10-15 minutes before taking it above 3000 RPM. Frequently Asked Questions Q: Are these compatible with B20 (non-VTEC) engines?A: No. The B20B/B20Z does not have VTEC and does not use LMAs. These are strictly for DOHC VTEC B-series heads. Q: Can I just replace the noisy ones?A: You can, but it's false economy. The labor to access LMAs (cam removal) is the same whether you replace 1 or 8. If a few have failed, the rest are not far behind. Replace all 8 as a set. Q: How do these compare to OEM Honda LMAs?A: These meet the same dimensional and spring-rate specifications as OEM Honda part 312-05-0200. They are a cost-effective alternative for engines where OEM parts have become discontinued or prohibitively expensive. Q: What's the difference between intake and exhaust LMAs?A: On B-series DOHC VTEC heads, the intake and exhaust LMAs are the same part — they are interchangeable. All 8 units in this kit are identical. Q: Do I need to bleed or prime these before installation?A: Soak the LMAs in clean engine oil for 10-15 minutes before installation to pre-fill the internal oil passages. After assembly, idle the engine for 10+ minutes to allow full oil pressure priming before driving.

Product Overview The iFJF Low Pressure Electric Fuel Pump is a direct replacement for the factory fuel pump on Volvo Penta 4.3L V6, 5.0L V8, and 5.7L V8 marine engines from 1992 through 2006. This pump delivers a consistent 4-7 PSI of fuel pressure to the carburetor — the exact specification these engines require. Whether you're replacing a failed pump, keeping a spare onboard, or doing a complete fuel system refresh, this pump provides reliable marine-grade performance at a fraction of dealer pricing. Key Features Marine-Specific Application: Designed for the unique demands of marine environments — corrosion-resistant housing, sealed electrical connections, and consistent flow characteristics in rough water conditions. Correct Pressure Range: Delivers 4-7 PSI — the target pressure for carbureted Volvo Penta V6 and V8 engines. Too much pressure floods the carb; too little starves the engine at WOT. 12V Universal Fit: Standard two-wire positive/negative connection. Includes mounting bracket and pre-attached fuel line fittings for common 5/16-inch and 3/8-inch marine fuel hose. Replaces OEM 21608511: Direct interchange with Volvo Penta part number 21608511 and equivalent aftermarket pumps. Quiet Operation: Rubber-isolated mounting bracket minimizes vibration transfer to the hull — a common complaint with generic electric pumps. Compatibility Table Year Make Engine Fuel System 1992-2006 Volvo Penta 4.3L V6 (GL, GS, GSi) Carbureted 1992-2006 Volvo Penta 5.0L V8 (GL, Gi) Carbureted 1992-2006 Volvo Penta 5.7L V8 (GS, GSi) Carbureted Specifications Specification Value Part Number (OEM) 21608511 Voltage 12V DC Pressure Range 4-7 PSI Flow Rate 30+ GPH (Free Flow) Inlet/Outlet 5/16-inch or 3/8-inch Hose Barb Polarity Negative Ground Signs Your Fuel Pump Needs Replacement Hard starting — engine cranks but takes excessive time to fire, especially after sitting Stalling under load — engine dies when you throttle up from idle No-start after winter storage — old fuel varnish seizes the pump internals Intermittent fuel delivery — engine surges or cuts out randomly on the water Audible pump failure — no clicking sound from the pump when the ignition is turned on Installation Guide Disconnect the battery before starting. Remove the old pump from its mounting bracket (typically on the port side of the engine near the fuel filter/separator). Transfer the bracket or use the included one. Connect the fuel lines — pay attention to flow direction (arrow on the pump body). Wire the red lead to ignition-switched 12V and the black lead to a clean ground. Prime the system by cycling the ignition 3-4 times before starting. Check all connections for leaks before heading out on the water. Frequently Asked Questions Q: Will this work on a Mercruiser 4.3L?A: While Mercruiser and Volvo Penta use similar GM-based blocks, fuel pump specifications may differ. Verify your Mercruiser's required fuel pressure before purchasing. This pump is specifically spec'd for Volvo Penta applications. Q: Can I use this for fuel injection (EFI/MPI) engines?A: No! EFI systems require 35-60 PSI. This is a low-pressure pump (4-7 PSI) for carbureted engines only. Using it on an EFI engine will result in a no-start condition. Q: Is this Coast Guard compliant for marine use?A: This pump is designed for marine engine compartments and uses sealed, ignition-protected construction. Always verify compliance with your local marine safety regulations. Q: Should I replace the fuel filter at the same time?A: Yes — absolutely. A new pump paired with an old, clogged fuel filter will fail prematurely. Replace the water-separating fuel filter and any inline filters simultaneously. Q: How long do these pumps typically last?A: In marine applications with regular use and clean fuel, expect 5-8 years of reliable service. Ethanol-blended fuels and long storage periods shorten pump life — consider adding a fuel stabilizer for winter layup.

Product Overview The iFJF Lower Door Insert Panels are designed to close the gap on Polaris RZR half doors — keeping mud, rocks, sticks, and trail debris out of the cabin. If you've ever taken your RZR through a mud hole only to have the floorboards fill with crud, you know exactly why these exist. These panels fill the lower opening on factory half doors, dramatically improving cabin cleanliness and passenger comfort without the cost or complexity of full door kits. Compatible with 2014-2020 Polaris RZR XP 1000 4-door and Turbo 4-door models. Key Features Keeps the Cabin Clean: Blocks mud, gravel, sticks, and water spray from entering through the lower door opening — your passengers stay clean and your interior stays dry. Clip-On Installation: No drilling, no cutting, no permanent modification. Panels attach to the factory half door frame using the included spring clips and mounting hardware. Installation takes 15-20 minutes per side. Heavy-Duty UV-Stabilized Poly: Made from thick, impact-resistant polymer that won't crack in sub-zero temperatures or warp in desert heat. Textured black finish matches factory interior plastics. 4-Door Set: This kit includes all four lower door inserts — front left, front right, rear left, rear right — for complete coverage on 4-door RZR models. OEM-Look Integration: Designed to blend with the factory door shape and interior styling — looks like it came from the Polaris factory, not a backyard garage mod. Compatibility Table Year Make Model Doors 2014-2020 Polaris RZR XP 1000 4-Door (Crew) 2016-2020 Polaris RZR XP Turbo 4-Door (Crew) 2015-2019 Polaris RZR 900 4-Door (Crew) Specifications Specification Value Material Impact-Resistant UV-Stabilized Polymer Finish Textured Black Fitment Factory Half Doors Only Kit Includes 4 Panels (Front L+R, Rear L+R), Clips, Hardware Installation Clip-On — No Drilling Required Why You Need Lower Door Inserts Polaris RZR half doors provide rollover protection and a secure armrest — but their open lower section is a major design compromise. Every trail ride becomes a cleanup session: mud on the seats, gravel in the cupholders, and water soaking the floor mats. Lower door inserts solve this problem at a fraction of the cost of full doors while maintaining the open-air feel that makes a RZR fun to drive. Unlike fabric door lowers that flap, sag, and tear, these rigid polymer panels stay put and last for years. Installation Guide Clean the inner door frame surface where the panel will attach. Position the lower insert against the door frame opening — align the mounting points. Attach spring clips to the panel edge tabs. Press the panel firmly onto the door frame — clips snap into place with an audible click. Secure any additional screw points through the provided pre-drilled holes. Repeat for the remaining three doors. Check that all panels are flush and secure before riding. Frequently Asked Questions Q: Will these fit a 2-door RZR?A: No. This kit is specifically for the 4-door (crew) RZR models. The 2-door lower door opening dimensions are different. Q: Are these compatible with aftermarket doors?A: These are designed for factory Polaris half doors. Aftermarket doors from companies like Pro Armor, Assault Industries, or DragonFire have different frame geometries — verify fitment before ordering. Q: Can I still use my factory door nets with these installed?A: Yes. The inserts mount to the lower door frame and do not interfere with the upper door net or latch mechanism. Q: Will these warp in high heat?A: The UV-stabilized polymer is rated for continuous exposure up to 180°F. Arizona summers and desert riding won't cause warping or deformation. Q: Can these be painted or wrapped?A: The textured surface accepts adhesion promoter and plastic-rated paint. For wraps, a light scuff with 400-grit sandpaper improves vinyl adhesion. Test a small area first.

John Deere Mower Deck Spindle Reinforcement Ring — Stop Deck Cracking Before It Starts The iFJF Spindle Reinforcement Ring is the most cost-effective upgrade you can make to your John Deere 42-inch mower deck. Factory decks are notorious for cracking around the spindle mounting area — this heavy-duty steel ring reinforces the weakest point and extends your mower deck's service life by years. Why You Need This John Deere 42" stamped decks (found on D100, D110, D120, D130, D140, LA100-Series, and X100-Series models) use thin-gauge steel that fatigues over time. The constant vibration and blade impact stress eventually cause hairline cracks radiating from the spindle bolt holes. Once cracks appear, the deck becomes unsafe and replacement costs $300-800. A simple reinforcement ring installed preventatively saves you hundreds. Key Features Precision Laser-Cut Steel — CNC laser-cut from 10-gauge American steel for exact fitment to John Deere 42" spindle bolt patterns. Prevents Costly Deck Replacement — Reinforces the #1 failure point on stamped mower decks, potentially saving $300-800 in replacement costs. Easy Bolt-On Installation — Installs between the spindle housing and deck surface using existing bolts. No drilling or welding required. Corrosion-Resistant Coating — Durable black finish stands up to grass moisture, fertilizer exposure, and outdoor storage. Universal 42" Deck Fitment — Compatible with nearly all John Deere 42-inch stamped deck models from 2003-present. Compatibility Series Models D100 Series D100, D110, D120, D130, D140, D150, D160, D170 LA100 Series LA100, LA105, LA110, LA115, LA120, LA125, LA130, LA135, LA140, LA145, LA150, LA155, LA165 X100 Series X110, X120, X140 L100 Series L100, L105, L107, L108, L110, L111, L118, L120, L130 Specifications Material 10-Gauge American Steel Finish Black Corrosion-Resistant Coating Compatible Deck Size 42 Inches Quantity 1 Ring (Single Spindle) Installation Bolt-On — Uses Existing Hardware Thickness Approximately 0.134 inch (10 GA) Installation Tips Remove mower deck from tractor and clean the spindle area thoroughly. Unbolt the spindle assembly — keep bolts and washers organized. Place the reinforcement ring between the spindle housing and the deck surface. Reinstall spindle bolts through the ring, deck, and into the spindle housing. Torque bolts to John Deere factory specifications (typically 35-45 ft-lbs). Reinstall deck and test for smooth operation before mowing. Frequently Asked Questions Will this fit my John Deere model? This ring is designed for John Deere 42-inch stamped decks found on D100, LA100, X100, and L100 series models. If your deck measures 42 inches and uses a stamped (non-fabricated) design, it should fit. Can I install this if my deck is already cracked? Minor hairline cracks can be stabilized with the reinforcement ring, but we recommend welding or replacing the deck if cracks are longer than 1 inch or have propagated to the deck edge. The ring works best as a preventative measure. Do I need both spindles reinforced? For a single-blade 42" deck, one ring is sufficient. For dual-blade decks, we recommend installing rings on both spindles (sold separately as a 2-pack — see related products). How thick is the steel? The ring is made from 10-gauge steel (~0.134 inch / 3.4mm), which is approximately 2-3x thicker than the factory deck material in the spindle area. Will this affect my deck warranty? If your mower is still under warranty, check with your dealer before installing. For out-of-warranty mowers (most D/LA/L series are 5+ years old), this is a smart preventative upgrade.

John Deere 42" Mower Deck Spindle Reinforcement Rings — 2-Pack Complete Kit Protect both spindles on your John Deere 42-inch mower deck with the iFJF 2-Piece Reinforcement Ring Kit. If you're running a dual-blade deck, reinforcing just one spindle leaves the other vulnerable — this complete kit provides balanced structural support across the entire deck. Key Features Complete 2-Spindle Coverage — Protects both spindle mounting points on dual-blade 42-inch decks. Ideal for LA-Series and X-Series models with twin blades. Laser-Cut 10-Gauge Steel — Each ring is precision-cut for exact bolt-hole alignment with John Deere factory spindle patterns. Preventative Deck Protection — Install before cracks appear to permanently eliminate the most common failure point on stamped mower decks. Bolt-On Simplicity — Uses existing spindle bolts; no drilling, welding, or deck modifications needed. Black Protective Coating — Rust-resistant finish engineered for the damp, acidic environment of grass clippings and fertilizer residue. Compatibility Series Models LA100 Series LA100, LA105, LA110, LA115, LA120, LA125, LA130, LA135, LA140, LA145, LA150, LA155, LA165 X100 Series X110, X120, X140 L100 Series L100, L105, L107, L108, L110, L111, L118, L120, L130 Sabre Select 42-inch deck models (verify bolt pattern before ordering) Scotts Select models manufactured by John Deere with 42-inch decks Specifications Material 10-Gauge Steel (0.134 inch) Quantity 2 Rings Finish Black Anti-Corrosion Coating Deck Compatibility 42-inch Stamped Decks Installation Type Bolt-On — No Modification Why the 2-Pack? Balanced Protection — Reinforcing one spindle while leaving the other unreinforced creates uneven stress distribution. The unreinforced side becomes the new weak point. Better Value — Two rings in one kit cost less than buying two singles. If you're already pulling the deck, do both spindles at once. Future-Proof Your Deck — Even if only one side shows wear today, the other side is on the same timeline. Install both and forget about deck cracks for the life of the mower. Installation Guide Disconnect spark plug and remove mower deck. Clean the spindle mounting area — remove all grass buildup and rust. Unbolt each spindle assembly (typically 4 bolts per spindle). Position one ring under each spindle housing, aligning bolt holes. Reinstall bolts through spindle → ring → deck in that order. Torque to 35-45 ft-lbs (refer to your model's service manual). Reinstall deck and test at idle before engaging blades. Frequently Asked Questions Do I really need both spindles reinforced? For a single-blade 42-inch deck, one ring (sold separately) is sufficient. For dual-blade decks (most LA and X series models), reinforcing both spindles is strongly recommended for balanced structural integrity. Will these work with a 48-inch deck? No — these rings are designed specifically for the 42-inch deck spindle bolt pattern. 48-inch decks use a different spindle assembly with different bolt spacing. Can I use these on a riding mower from another brand? These rings are precision-engineered for John Deere 42-inch stamped deck bolt patterns. They may fit some MTD or AYP-manufactured decks with identical bolt patterns, but we recommend verifying your bolt spacing before ordering. What if my deck is already cracked? Minor cracks (under 1 inch, not reaching deck edge) can be stabilized by these rings. For significant cracking, we strongly recommend welding repair + ring reinforcement or full deck replacement. Do not operate a mower with a structurally compromised deck. How long does installation take? Plan for 45-90 minutes including deck removal and reinstallation. The ring installation itself takes about 10 minutes per spindle once the deck is accessible.

Specifications Position Front Lower Side Driver (LH) or Passenger (RH) Material Forged Steel with E-Coat Finish Bushing Type OE-Spec Rubber Ball Joint Pre-Installed & Greased Installation Direct Bolt-On Replacement Symptoms of a Worn Control Arm Clunking or knocking over bumps, especially at low speeds Steering wander — vehicle drifts or pulls without steering input Uneven tire wear — inner or outer edge wearing faster than the rest of the tread Vibration through the steering wheel at highway speeds Visible bushing cracks — rubber bushings showing dry rot, cracking, or separation from the metal sleeve Frequently Asked Questions Do I need an alignment after replacing a control arm? Yes — a professional wheel alignment is strongly recommended after any control arm replacement. The new arm may position the wheel slightly differently than the worn one, and incorrect alignment will cause rapid tire wear. Can I replace just one control arm? While you can replace just one, suspension components wear as pairs. If one side's bushings are worn, the other side is likely close behind. For best results and even handling, replace both sides simultaneously. How difficult is this to install at home? Moderate difficulty. You'll need a floor jack, jack stands, basic socket set, and a torque wrench. The main challenge is typically the ball joint separation, which may require a pickle fork or ball joint separator tool. Budget 1-2 hours per side for a DIY install. What torque specs should I use? Refer to your vehicle's factory service manual for exact specifications. Typical values range from 80-120 ft-lbs for control arm mounting bolts and 50-80 ft-lbs for ball joint nuts. How long do aftermarket control arms last? With proper installation and alignment, iFJF control arms typically last 50,000-80,000 miles under normal driving conditions — comparable to OE parts at a fraction of the cost.

Specifications Position Front Lower Rearward Quantity 2 Arms (LH & RH Pair) Material Forged Steel Bushing Material OE Rubber Compound Ball Joint Pre-Installed, Sealed, Pre-Greased Finish Black E-Coat (Electrophoretic) Professional Installation Notes Always support the vehicle with jack stands — never rely on a floor jack alone. Mark the camber bolt position (if equipped) before removal to preserve approximate alignment. Use a ball joint separator tool — avoid damaging the boot with a pickle fork if reusing nearby components. Tighten all bushing bolts with the suspension at ride height (vehicle weight on the ground) to prevent premature bushing failure. Schedule a professional alignment immediately after installation. Frequently Asked Questions What's the difference between forward and rearward control arms? On vehicles with a multi-link or double-wishbone front suspension, the lower control arm is often split into two separate arms — forward (front) and rearward (rear). Each handles different load directions. This kit replaces the rearward pair. Why should I replace both sides together? Control arms wear symmetrically. Replacing only one side creates a handling imbalance — the old side will have more compliance (slop) than the new stiff side, leading to pulling and uneven tire wear. Do these come with mounting hardware? Control arms include pre-installed bushings and ball joints. Mounting bolts and nuts are typically reused from your vehicle unless they show signs of corrosion or stretching. We recommend using new hardware if your existing bolts show any rust or thread damage. Can I do this job without a lift? Yes — floor jack and jack stands are sufficient. The biggest challenge is accessing the mounting bolts, which may require a breaker bar and penetrating oil on older, rust-belt vehicles. Expect 2-4 hours for a DIY install of both sides.

NOx Nitrogen Oxide Sensor 5WK96668B — OEM-Grade Emissions Control Replacement The iFJF NOx Sensor 5WK96668B is a direct plug-and-play replacement for your vehicle's factory nitrogen oxide sensor. Engineered to meet or exceed OEM specifications, this sensor restores proper DEF/SCR system function, eliminates check engine lights triggered by NOx sensor fault codes, and helps your diesel engine pass emissions testing. What a NOx Sensor Does Nitrogen Oxide (NOx) sensors monitor the concentration of harmful nitrogen oxides in your diesel exhaust stream — both before and after the Selective Catalytic Reduction (SCR) catalyst. The engine control module (ECM) uses this data to precisely meter Diesel Exhaust Fluid (DEF) injection. When a NOx sensor fails, the ECM can't regulate DEF dosing properly, leading to increased emissions, reduced fuel economy, and potential limp-mode activation. Key Features OE-Equivalent Performance — Calibrated to match the voltage curve and response time of the factory sensor for seamless ECM integration. Plug-and-Play Installation — Pre-terminated connector matches factory wiring harness. No splicing, no programming — remove the old sensor and install the new one. Durable Construction — High-temperature ceramic sensing element with stainless steel probe body withstands exhaust temperatures up to 930°C (1,700°F). Clears NOx-Related Fault Codes — Resolves common DTCs related to NOx sensor performance, circuit range, and rationality errors. 12-Month Warranty — Backed by iFJF's quality guarantee against manufacturing defects.

No — this is a plug-and-play sensor. The ECM will automatically recognize the new sensor on the next key cycle. However, you may need to clear existing fault codes with an OBD-II scanner. Some vehicles require a short drive cycle (10-20 miles) for the sensor to fully calibrate and for readiness monitors to set. How do I know if my NOx sensor needs replacement? The most common indicators are: (1) check engine light with NOx-related DTCs, (2) failed emissions test with high NOx readings, and (3) visible physical damage to the sensor or wiring harness. A professional diesel shop can confirm the diagnosis with a scan tool by comparing upstream and downstream NOx readings. What's the difference between upstream and downstream NOx sensors? Upstream (pre-SCR) sensors measure NOx entering the catalyst. Downstream (post-SCR) sensors measure NOx exiting the catalyst. They may look identical physically but are typically calibrated differently. Verify your vehicle's exact position before ordering. Can a bad NOx sensor cause DEF system problems? Yes — the ECM relies on NOx sensor data to calculate DEF injection rates. A faulty sensor sending incorrect data can cause over-injection (wasting DEF fluid) or under-injection (failing emissions standards). Either scenario can trigger additional fault codes. How long should a NOx sensor last? Factory NOx sensors typically last 80,000-150,000 miles depending on driving conditions. Contaminated DEF fluid, excessive idling, and high-sulfur fuel can significantly reduce sensor life. If one sensor has failed, the others on the vehicle may not be far behind.

No — this is a plug-and-play sensor. The ECM will automatically recognize the new sensor on the next key cycle. However, you may need to clear existing fault codes with an OBD-II scanner. Some vehicles require a short drive cycle (10-20 miles) for the sensor to fully calibrate and for readiness monitors to set. How do I know if my NOx sensor needs replacement? The most common indicators are: (1) check engine light with NOx-related DTCs, (2) failed emissions test with high NOx readings, and (3) visible physical damage to the sensor or wiring harness. A professional diesel shop can confirm the diagnosis with a scan tool by comparing upstream and downstream NOx readings. What's the difference between upstream and downstream NOx sensors? Upstream (pre-SCR) sensors measure NOx entering the catalyst. Downstream (post-SCR) sensors measure NOx exiting the catalyst. They may look identical physically but are typically calibrated differently. Verify your vehicle's exact position before ordering. Can a bad NOx sensor cause DEF system problems? Yes — the ECM relies on NOx sensor data to calculate DEF injection rates. A faulty sensor sending incorrect data can cause over-injection (wasting DEF fluid) or under-injection (failing emissions standards). Either scenario can trigger additional fault codes. How long should a NOx sensor last? Factory NOx sensors typically last 80,000-150,000 miles depending on driving conditions. Contaminated DEF fluid, excessive idling, and high-sulfur fuel can significantly reduce sensor life. If one sensor has failed, the others on the vehicle may not be far behind.
