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.

Solve the 5.9L Cummins' uneven cooling problem with the iFJF Coolant Bypass Kit. The factory cooling system on 2003-2007 Dodge Ram Cummins engines suffers from poor coolant circulation at the rear cylinders (cylinders 5 and 6), which run significantly hotter than the front cylinders. This temperature imbalance leads to premature wear, reduced performance, and potential head gasket issues. Our bypass kit redirects coolant flow to ensure consistent temperatures across all six cylinders, extending engine life and improving overall reliability. Key Features & Benefits Lower Rear Cylinder Temperatures: Actively reduces coolant temperature at cylinders 5 and 6 by up to 30°F, eliminating the factory hot-spot that accelerates engine wear. High-Quality Aluminum Construction: CNC-machined from billet aluminum with a corrosion-resistant finish — built to handle diesel coolant chemistry and vibration. Metal & Polyester-Reinforced Hoses: Durable hoses designed to withstand high coolant temperatures and pressures without ballooning or cracking. Even Cooling Across All Cylinders: Ensures consistent temperature distribution, reducing thermal stress on the head gasket and cylinder head. Extended Engine Life: Even cooling means less thermal cycling stress, longer head gasket life, and more miles between rebuilds. Complete Bolt-On Kit: Includes all hoses, fittings, clamps, and mounting hardware. No cutting or permanent modification required. Vehicle Compatibility Year Make Model Engine Notes 2003-2007 Dodge Ram 2500 5.9L Cummins ISB Direct Fit 2003-2007 Dodge Ram 3500 5.9L Cummins ISB Direct Fit Technical Specifications Material Billet Aluminum + Metal/Polyester Hoses Kit Type Coolant Bypass Kit (Complete) Temperature Reduction Up to 30°F at Rear Cylinders Installation Bolt-On (No Cutting Required) Installation Time 2-3 Hours Installation Guide Installation is straightforward with basic hand tools. The kit mounts at the rear of the cylinder head near the heater core connections. Drain a portion of the coolant, install the bypass fittings at the specified locations, route the hoses, and secure with the provided clamps. Refill and bleed the cooling system. A coolant flush is recommended before installation for optimal results. Estimated DIY time: 2-3 hours. Frequently Asked Questions Q: Why do the rear cylinders run hotter on a 5.9L Cummins?A: The factory cooling system design sends coolant from the water pump through the front of the block first. By the time coolant reaches cylinders 5 and 6 at the rear, it has already absorbed significant heat. The bypass kit provides a secondary coolant path to the rear, equalizing temperatures. Q: Will this fix my head gasket issues?A: While it won't fix an already-blown head gasket, installing this bypass kit can help prevent future head gasket failures by reducing thermal stress from uneven cylinder temperatures. Combine it with ARP head studs for maximum protection. Q: Is this compatible with a coolant filtration system?A: Yes! This bypass kit works alongside coolant filtration systems. In fact, using both together provides the best protection — filtered coolant with even temperature distribution.

Our polyester webbing straps are a permanent fix that actually looks better than OEM. Each strap is hand-stitched with reinforced end loops for long-term durability on and off the trail. 90-day satisfaction guarantee. Frequently Asked Questions Q: Do these completely replace the factory door check?A: Yes. These straps replace the entire factory door check assembly. Remove the old check strap from the door and body mounting points, then bolt these in using the same hardware. No drilling or permanent modification required. Q: Will these work with tube doors?A: Tube doors typically use different mounting geometry than factory doors. While many customers have successfully adapted these straps, check your tube door's mounting hole spacing and bracket design before ordering. Q: Can I still remove my doors easily?A: Yes. Simply unbolt the strap from either the door or body side (one bolt) and the door functions as normal for door-off summer driving. Re-attach when you put the doors back on for the season. Q: How much door opening do these allow?A: The strap length is calibrated to the factory-designed door opening angle — approximately 75-80 degrees on most Wrangler models. This prevents over-extension while still providing full cabin access. Q: Are these better than the factory door checks?A: Yes. Factory door checks use plastic and rubber components that deteriorate from UV exposure, temperature cycling, and age. These polyester straps are inherently more durable and provide consistent, reliable door control year after year.

Our polyester webbing straps are a permanent fix that looks better than OEM. The vibrant red color makes a bold statement whether you're running doors on the trail or parked at a Jeep meet-up. 90-day satisfaction guarantee. Frequently Asked Questions Q: Do these completely replace the factory door check?A: Yes. These straps replace the entire factory door check assembly. Remove the old check strap from the door and body mounting points, then bolt these in using the same hardware. No drilling or permanent modification required. Q: Will the red color fade over time?A: The polyester webbing is UV-treated to resist fading from sun exposure. With normal use, the red color should remain vibrant for years. For maximum longevity, apply a UV protectant spray periodically if your Jeep is parked outdoors full-time. Q: Can I still remove my doors easily?A: Yes. Simply unbolt the strap from either the door or body side (one bolt) and the door functions as normal for door-off summer driving. Re-attach when you put the doors back on. Q: Are the red straps the same length as the black/orange version?A: Yes. Both color variants use identical strap length and mounting hardware. The only difference is the webbing color and accent stitching. Choose the style that matches your Jeep's personality. Q: How much door opening do these allow?A: The strap length is calibrated to the factory-designed door opening angle — approximately 75-80 degrees on most Wrangler models. This prevents over-extension while still providing full cabin access.
