A3231C Heavy-Duty Air Filter for 2017-2019 Duramax L5P 6.6L The iFJF A3231C Engine Air Filter is purpose-built for the most powerful Duramax ever made — the 2017-2019 6.6L L5P turbo diesel V8 producing 445 horsepower and 910 lb-ft of torque. This engine demands an air filter that can flow massive volumes of clean air without restriction — especially when towing at highway speeds or climbing grades under load. This direct OEM-replacement filter delivers exactly that. The L5P's variable-geometry turbocharger (VGT) is a precision component with turbine blades spinning at over 100,000 RPM. A single grain of sand passing through a cheap air filter can erode the compressor wheel — causing imbalance, reduced boost, and eventual turbo failure. The A3231C's multi-layer synthetic-blend media ensures only clean air reaches your turbo. Key Features L5P-Specific Design: Engineered specifically for the 2017-2019 Duramax L5P airbox — not a universal filter adapted to fit. Matches the factory filter's dimensions, seal profile, and airflow characteristics precisely OEM Direct Replacement: Replaces GM part number 84262965 and ACDelco A3231C Maximum Airflow: Ultra-high-capacity pleated media designed for the L5P's class-leading 445hp/910lb-ft output — zero restriction at full throttle under load Towing-Ready Durability: Reinforced filter construction prevents collapse during sustained high-load operation — essential for towing heavy trailers at highway speeds Advanced Filtration: Multi-layer synthetic-blend media captures fine particulates that can damage the L5P's precision VGT turbocharger 45,000-Mile Service Life: Recommended replacement interval under normal highway/towing conditions Vehicle Compatibility Make Model Engine Years Chevrolet Silverado 2500HD 6.6L Duramax L5P V8 Turbo Diesel 2017-2019 Chevrolet Silverado 3500HD 6.6L Duramax L5P V8 Turbo Diesel 2017-2019 GMC Sierra 2500HD 6.6L Duramax L5P V8 Turbo Diesel 2017-2019 GMC Sierra 3500HD 6.6L Duramax L5P V8 Turbo Diesel 2017-2019 FAQ Q: Will this fit my 2018 L5P? A: Yes — designed specifically for 2017-2019 Silverado/Sierra 2500HD and 3500HD with the 6.6L Duramax L5P diesel engine. Matches the factory filter box dimensions and seal perfectly. Q: How often should I replace the air filter on my L5P? A: GM recommends replacement at 45,000 miles under normal conditions. If you drive on dirt/gravel roads, tow frequently, or live in dusty environments (desert southwest, agricultural areas), inspect every 15,000 miles and replace by 22,500 miles. A dirty air filter on a turbo diesel reduces boost pressure, increases EGTs, and kills fuel economy. Q: Is this a washable/reusable filter like K&N? A: No — this is a traditional dry media filter, not an oiled cotton gauze filter. Dry filters are recommended for the L5P because (1) they don't risk oil contamination of the MAF sensor, and (2) they provide more consistent filtration throughout their service life without the cleaning/re-oiling maintenance cycle that oiled filters require. Q: Can I use this on a 2020+ L5P? A: The 2020+ Silverado/Sierra HD uses a different airbox design. This filter is specifically for 2017-2019 model years. Check your owner's manual for the correct part number for 2020+ models. Q: What are signs my Duramax air filter needs replacement? A: Watch for: (1) Reduced fuel economy — a clogged air filter richens the air-fuel mixture; (2) Black smoke under acceleration — incomplete combustion from restricted airflow; (3) Lower boost pressure on your gauge if equipped; (4) Visual inspection — hold the filter up to sunlight; if you can't see light through the media, it's time to replace. Q: Does a performance air filter increase horsepower? A: On a stock L5P, the factory airbox and filter flow more than enough air for the 445hp rating. A clean, high-quality OEM-spec filter like the A3231C maintains that flow — but don't expect horsepower gains from the filter alone. For significant airflow increases, a complete aftermarket intake system is required. Q: How do I find the right air filter for my Duramax by part number?A: Search by the exact part number printed on your existing filter: A3231C (ACDelco number) or 84262965 (GM OEM number). These are the two most common search terms Duramax L5P owners use. The A3231C is specifically for 2017-2019 L5P engines — 2020+ models use a different airbox and filter design. Always match the number on your old filter to ensure correct fitment. 📖 Related Guides Duramax 6.6L L5P Fuel Filter Replacement: Complete Step-by-Step Guide

Product Overview Unlock the true off-road potential of your Jeep Wrangler JK with the iFJF Quicker Disconnect Swaybar Link System. The factory sway bar limits wheel articulation to roughly 6-8 inches — enough for highway stability but a major handicap on rocks. This adjustable quick-disconnect system releases both sway bar links in under 30 seconds (two quick-release pins per side) for up to 30% more wheel travel. When it's time to hit pavement, reconnect just as fast — no tools, no crawling underneath, no alignment reset. Key Features 2-Pin Quick Removal — Pull two stainless steel retaining pins per side to free the sway bar. 30 seconds to disconnect, 30 seconds to reconnect. Adjustable for 2.5"-6" Lifts — Threaded heim joint design provides infinite length adjustment to maintain proper sway bar geometry at any lift height. Replace #2030/#2034 — Direct upgrade replacement for fixed-mount JKS 2030/2034 sway bar disconnects, adding the quick-release feature those systems lack. Greaseable Chromoly Heim Joints — PTFE-lined spherical rod ends with grease zerks. Silent operation, zero-slop articulation, replaceable when worn. Massive Off-Road Flex — Disconnected sway bar allows each axle to move independently, keeping all 4 tires planted on uneven terrain. Compatibility Make Model Years Lift Range Jeep Wrangler JK 2-Door 2007-2018 2.5" - 6" Jeep Wrangler JK Unlimited 2007-2018 2.5" - 6" Specifications Specification Detail Link Material DOM steel tube (powder coated) Joint Type Chromoly heim (greaseable, PTFE-lined) Pin Type Stainless steel quick-release Adjustment 2.5" - 6" lift height SKU JP-FS01-ZH Frequently Asked Questions Q: How fast is disconnect/reconnect?A: ~30 seconds per side. Pull two pins, swing link up, secure with parking strap. Reconnecting is just as fast. Q: Will these rattle on the street?A: Our PTFE-lined heim joints run silent when properly greased. A shot of grease through the zerk fitting quiets any noise instantly. Q: Do I need to disconnect both sides?A: Yes — for maximum articulation, disconnect both sides. Single-side disconnect limits flex and stresses the connected link unevenly. Q: Can I drive highway speeds disconnected?A: NO. Driving at highway speeds with sway bar disconnected is extremely dangerous — excessive body roll and unpredictable handling. Always reconnect before pavement. Q: What maintenance is required?A: Grease heim joint zerks every 3-4 trail trips. Inspect retaining pins annually. Replace heim joints when play develops (typically 2-3 years of heavy use).

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. Compatibility Make Models OEM Ref Hino Multiple truck models 89463-E0451 Cross-Reference / OEM Part Numbers Manufacturer Part Number(s) Hino 89463-E0451 Continental/VDO 5WK96668B Specifications Sensor Type Nitrogen Oxide (NOx) Sensor Model 5WK96668B Connector Type Pre-Terminated Factory Match Probe Material Stainless Steel with Ceramic Element Operating Temperature Up to 930°C (1,700°F) Installation Plug-and-Play (No Programming) Warranty 12 Months Symptoms of a Failing NOx Sensor Check Engine Light (CEL/MIL) — Common fault codes: P2200-P2214 (NOx sensor circuit), P229E/P20EE (SCR NOx efficiency) Failed Emissions Test — Vehicle produces excessive NOx emissions during inspection Increased DEF Consumption — ECM overcuts DEF trying to compensate for bad sensor readings Reduced Fuel Economy — Engine may run in a less efficient mode when NOx sensor data is unreliable Limp Mode / Reduced Power — In severe cases, the ECM may limit engine power to protect the emissions system Frequently Asked Questions Do I need to reprogram the ECM after installing this sensor? 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.

To test: jack up the ATV, grab the tire at 12 and 6 o'clock, and rock it — any play indicates worn bearings. Q: Can I replace just one side?A: We recommend replacing both sides at the same time. Bearings wear at similar rates, and if one side is gone, the other is usually not far behind. This kit includes components for both sides. Q: What tools do I need for this job?A: You'll need a bearing press or a bearing driver kit, snap ring pliers, socket set, torque wrench, and a dead blow hammer. A hydraulic press makes the job straightforward. Without one, you can use the freezer/heat method (freeze bearings, heat hub with a heat gun), but a press is strongly recommended.Related Guides & Articles📖 ATV Wheel Bearing Replacement: Step-by-Step DIY Guide

The iFJF 385310076 Duckbill Valve Kit includes two premium nitrile valves sized for all Sealand S-Series and T-Series vacuum generators. Rebuild your pump in under 30 minutes and restore factory vacuum performance. Key Features Complete 2-Pack Value: Both inlet and outlet valves needed for a proper pump rebuild. Replace both while you have the housing open. Premium Nitrile Rubber: Resists chemical attack from holding tank treatments — outlasts generic silicone valves by 2-3x in chemical-rich environments. Universal S&T Fit: Compatible with S12D, S24D, S32D, T12, T24, T32, and VHT/VG series vacuum generators. OEM-Dimension Match: Precise lip geometry ensures complete one-way seal — no vacuum loss between flushes. Includes Silicone Grease: Pre-applied lubrication prevents tearing during installation and ensures a perfect seal. Compatibility Pump Series Models S-Series S12D, S12DAB, S24D, S32D, S115A, S12, 52A, S32 T-Series T12, T24, T32 VHT/VG VHT12, VHT24, VG4, VG5 Specifications Spec Value Part Number 385310076 Material Premium Nitrile Rubber Valve Type One-Way Duckbill Check Valve Quantity 2 (Inlet + Outlet) Includes 2x Valves + Silicone Grease Packet Symptoms of Failed Duckbill Valves Pump runs continuously without building pressure Weak or incomplete flushes — bowl doesn't clear completely Pump cycles every few minutes without anyone flushing Foul odor from vacuum tank area Hissing sound near pump housing during operation Vacuum gauge shows pressure bleed-down Installation Guide Turn off power at breaker. Locate vacuum generator pump. Remove pump housing cover (4-6 screws depending on model). Note orientation: tapered beak faces toward holding tank on both valves. Remove old valves carefully — they may be brittle. Clean mounting surfaces with a rag. Apply included silicone grease to the lip of each new valve. Press new valves firmly into their seats. Ensure full perimeter contact. Reassemble housing, tighten screws evenly. Restore power. Test with 3-4 flushes. Verify pump shuts off and vacuum holds for 2+ minutes. Frequently Asked Questions Q: How do I know which valve is bad — inlet or outlet?A: Listen near each valve while pump runs — hissing indicates a leak at that valve. Vacuum bleeding immediately after pump stops suggests inlet valve failure. Slow to build vacuum but holds once achieved points to outlet valve wear. When in doubt, replacing both is recommended. Q: How often should duckbill valves be replaced?A: Replace every 2-3 years under normal recreational use. Liveaboards and full-time RVers should replace annually. If you use formaldehyde-based holding tank chemicals, inspect every 6 months — chemicals accelerate rubber degradation significantly. Q: Why buy the 2-pack instead of single valves?A: Both valves wear at similar rates. If one has failed, the other is likely close behind. Replacing both saves you from opening the pump housing again in a few months — and costs less than two single purchases. Q: Will these fit my older Sealand pump?A: Yes. The 385310076 duckbill valve fits all S-Series and T-Series Sealand/Dometic vacuum generators dating back to the 1990s. The design has not changed. Q: Can I do this repair myself?A: Absolutely. This is a 20-30 minute DIY job requiring only a screwdriver. No plumbing or electrical expertise needed. We include step-by-step instructions in every kit. Q: What happens if I install a valve backward?A: The pump will run continuously but never build vacuum — the valve will be forced open instead of sealing. The tapered beak MUST face toward the holding tank. If you make this mistake, simply open the housing and flip the valve around.

29539579 Spin-On Transmission Fluid Filter — Allison 1000/2000/2400 Series The iFJF 29539579 Spin-On Automatic Transmission Fluid Filter is a direct replacement for Allison 1000, 2000, and 2400 series automatic transmissions found in GM Duramax diesel trucks and medium-duty commercial vehicles. This filter replaces the old-style Allison part number 29537268 and provides high-efficiency filtration to protect your transmission's valve body, clutch packs, and torque converter from wear particles and debris. Allison transmissions are known for their durability — regularly reaching 300,000+ miles in commercial service — but they require clean ATF to achieve that lifespan. Contaminated fluid causes sticking valves, delayed shifts, and accelerated clutch wear. This spin-on filter captures particles as small as 25 microns while maintaining full transmission fluid flow under all operating conditions — from cold morning starts to heavy towing at highway speeds. Key Features Direct Allison Replacement: Replaces Allison 29539579 and old-style 29537268 spin-on transmission filters — exact dimensional match, guaranteed fit High-Efficiency Filtration: Multi-layer media captures wear particles, clutch material, and debris down to 25 microns — protecting precision valve body components Heavy-Duty Construction: Thick-gauge steel canister with corrosion-resistant coating withstands under-vehicle exposure to road salt, water, and debris Spin-On Design: Quick external filter change — no dropping the transmission pan required Silicone Anti-Drainback Valve: Maintains fluid in the filter between starts for immediate transmission protection on cold starts Transmission Compatibility Transmission Series Fluid Type Allison 1000 5-speed / 6-speed automatic TES-295 / TES-668 ATF Allison 2000 5-speed / 6-speed automatic TES-295 / TES-668 ATF Allison 2400 6-speed automatic TES-295 / TES-668 ATF Common Vehicle Applications Year Make Model Engine 2001-2019 Chevrolet Silverado 2500HD / 3500HD 6.6L Duramax V8 2001-2019 GMC Sierra 2500HD / 3500HD 6.6L Duramax V8 Various Multiple Medium-duty trucks, buses, specialty vehicles Allison-equipped platforms Technical Specifications Specification Value Filter Type Spin-On External Transmission Filter Replaces Allison 29539579, 29537268 (old style) Filtration Rating 25 micron absolute Thread Size Allison OEM-spec Service Interval Every transmission fluid change (25,000-50,000 miles depending on duty cycle) SKU FJ-9579 Why Replace Your Allison Transmission Filter? The Allison 1000/2000/2400 uses an external spin-on filter as its primary filtration stage (the internal pan filter is secondary). Over time, this external filter loads with clutch friction material, metal wear particles from gears and bearings, and oxidized fluid debris. A clogged filter restricts ATF flow — causing delayed engagement, slipping shifts, overheating, and eventual transmission failure. Replacing the spin-on filter at every fluid change is the simplest and most effective thing you can do for Allison transmission longevity. FAQ Q: Is this the spin-on external filter or the internal pan filter? A: This is the external spin-on filter — the one accessible without dropping the transmission pan. Allison 1000/2000/2400 transmissions use two filters: (1) An external spin-on filter (this part) that captures larger particles and is changed every fluid service, and (2) An internal pan filter that requires dropping the pan for replacement during major services. Replace the spin-on filter at every ATF change for maximum protection. Q: Does this fit my 2006 Duramax with Allison transmission? A: Yes — every Duramax-powered Silverado HD and Sierra HD from 2001 through 2019 uses the Allison 1000 series transmission (5-speed or 6-speed depending on year). This filter fits all of them. If your truck has the 6.6L Duramax diesel, it has an Allison — and this is the correct spin-on filter. Q: What's the difference between 29539579 and 29537268? A: 29537268 is the old-style Allison part number that has been superseded by 29539579. The 29539579 is the current production filter with improved media and anti-drainback valve design. Our filter replaces both numbers — if your service manual calls for either, this is the correct part. Q: How often should I change the Allison transmission spin-on filter? A: Allison recommends filter replacement at every transmission fluid change interval: 25,000 miles for severe duty (towing, commercial use, stop-and-go) and 50,000 miles for normal highway driving. Many Duramax owners servicing their own trucks change the spin-on filter at 30,000-mile intervals and do a full pan-drop with internal filter at 60,000-90,000 miles. Always follow your owner's manual for the specific Allison transmission in your vehicle. Q: What transmission fluid should I use with this filter? A: Use Allison-approved TES-295 or TES-668 specification ATF. Common options include Allison TranSynd, Mobil Delvac 1 ATF, and Castrol TranSynd. Do NOT use Dexron III or conventional ATF — Allison transmissions require TES-295 spec synthetic fluid. Using the wrong fluid can cause shift quality issues and accelerated wear. Check your owner's manual for the exact fluid specification for your model year. Q: Can I use this filter on a non-Allison transmission? A: No — this filter is specifically designed for Allison 1000, 2000, and 2400 series automatic transmissions. The thread pattern, gasket surface, and bypass valve settings are unique to Allison spin-on filter mounts. Using this on a different transmission (such as the GM 4L80E or Ford TorqShift) will result in a poor fit or no fit at all. Always verify your transmission model before ordering. Q: Do I need to drop the transmission pan to change this filter? A: No — the spin-on external filter is accessible from underneath the vehicle without removing the transmission pan. A standard filter wrench (or strap wrench for tight spaces) is all you need. Expect to lose about 0.5-1 quart of ATF when the filter is removed — have a drain pan ready. Top off the transmission fluid level after installation using the correct TES-295 spec ATF. 📖 Related Guides Duramax 6.6L Oil Change: Complete DIY Guide 🔧 Related Products TP3018 Fuel Filter — fuel/water separator for Duramax 6.6L TP3018 + 29539579 Combo — fuel filter + transmission filter bundle Fuel Filter Housing — billet aluminum 12642623 assembly
