  • 6PCS Torx Screw Bolts for 2018-2020 Jeep Wrangler JL — Windshield &… — Main Product Image

    iFJF 6PCS Torx Screw Bolts for 2018-2020 Jeep Wrangler JL — Windshield &…

    6PCS Torx Screw Bolt Kit for 2018-2020 Jeep Wrangler JL / JLU Replace your worn, stripped, or lost Torx hardware with this premium 6-piece stainless steel bolt kit. Designed specifically for the 2018-2020 Jeep Wrangler JL (2-door and 4-door JLU), these OEM-spec T40 Torx screws fit the windshield frame, windshield hinges, full/half door hinges, and roll bar mounts. Whether you're refitting after a windshield fold-down, doing a door-off summer setup, or replacing corroded factory fasteners, this kit has you covered. Key Features Premium Stainless Steel Construction: Corrosion-resistant 304 stainless steel — far more durable than factory carbon steel bolts that rust after one winter season. Exact OEM Specification: T40 Torx drive with identical thread pitch, length, and shoulder dimensions to factory hardware. No modification required. Complete 6-Piece Set: Includes all Torx bolts needed for windshield frame hinges, door hinges, and roll bar attachments — one kit covers multiple locations. Anti-Seize Pre-Treatment: Bolts ship with a light anti-seize coating to prevent galling and make future removal effortless. Made for Door-Off Lifestyle: Frequent JL owners who run doorless know factory bolts round out fast. These stainless replacements provide years of on/off cycles. Compatibility Vehicle Year Range Locations Jeep Wrangler JL (2-Door) 2018–2020 Windshield frame · Windshield hinges · Full/Half door hinges · Roll bar Jeep Wrangler JLU (4-Door) 2018–2020 Windshield frame · Windshield hinges · Full/Half door hinges · Roll bar Note: These are T40 Torx screws specifically for hinge and frame mounting points — not the smaller windshield-to-cowl bolts (those use T30). Verify your bolt size before ordering. Specifications Specification Value Material 304 Stainless Steel Drive Type T40 Torx Quantity 6 pieces Thread Type Metric — OEM match Corrosion Resistance Grade 304 — salt spray tested Finish Natural stainless (silver) Applications Windshield frame, door hinges, roll bar Why Choose iFJF Factory JL Torx bolts are carbon steel with a thin zinc coating — one Midwest winter and they're rusted solid. Our 304 stainless replacements eliminate this headache permanently. Each bolt is CNC-machined to exacting tolerances and pre-treated with anti-seize for smooth installation. iFJF stands behind every fastener with a satisfaction guarantee. When you're tired of PB Blaster and stripped Torx heads, upgrade to stainless. Frequently Asked Questions Q: Will these fit my 2021+ Jeep Wrangler JL?A: Jeep made minor revisions to some hinge bolt specifications for 2021+. While many customers report successful fitment on 2021+ models, we officially guarantee fitment for 2018-2020 JL/JLU only. Measure your existing bolt before ordering for 2021+ vehicles. Q: Do I need a T40 bit to install these?A: Yes, a T40 Torx bit (or Torx socket) is required. A standard T40 bit in a 3/8" ratchet or impact driver works best. Do NOT use a T45 or Allen key — you'll round the drive. Q: Can I use an impact driver?A: Hand-tightening with a ratchet is recommended for windshield hinge bolts to avoid stripping the body threads. Door hinge bolts can be run in with an impact driver on low torque setting, but final tighten by hand to 18-22 ft-lbs. Q: Why do factory bolts rust so quickly?A: OEM JL bolts are carbon steel with a thin electroplated zinc coating. Once the coating scratches during the first removal, bare steel is exposed. Road salt, humidity, and car washes accelerate corrosion. Stainless steel doesn't have this problem. Q: Do these come with the nylon locking patch like OEM?A: These are smooth-thread bolts — the nylon locking patch is not applied. Factory nylon patches wear off after 2-3 removal cycles anyway. For vibration resistance, apply a small drop of blue Loctite (242) to the threads before installation. Q: Can I use these for the hardtop mounting bolts?A: No. Hardtop mounting bolts use a different thread pitch and length. This kit is specifically for windshield hinges, door hinges, and roll bar hardware. Hardtop hardware is sold separately.

  • Adjustable Roll Bar Fire Extinguisher Holder for Jeep Wrangler JK 2007-2018 - 3lb Red — Front View

    iFJF iFJF Adjustable Roll Bar Fire Extinguisher Holder for Jeep Wrangler JK 2007-2018 - 3lb Red

    1 review

    High-Visibility Fire Extinguisher Mount for Jeep Wrangler JK The iFJF Adjustable Roll Bar Fire Extinguisher Holder in eye-catching red gives you the same rugged functionality as our black version, with the added benefit of high visibility. In an emergency, every second counts — the bright red finish makes your extinguisher instantly visible from any angle. Engineered specifically for the Jeep Wrangler JK (2007–2018) roll bar, this mount features a fully adjustable clamp design with rubber-lined contact surfaces that grip firmly without damaging your roll bar. Key Features High-Visibility Red Finish — Instantly locate your extinguisher in low light or emergency situations Adjustable Roll Bar Fit — Compatible with all Jeep Wrangler JK (2007–2018) 2-door and 4-door roll bars 3lb Fire Extinguisher Capacity — Fits standard 3lb automotive extinguishers (sold separately) Quick-Release Strap — Deploy your extinguisher in under 2 seconds Powder-Coated Steel Construction — Red finish resists rust, corrosion, fading, and chipping No-Drill Installation — Clamp-on design requires zero permanent modifications Rubber-Lined Clamps — Protects roll bar finish and eliminates rattles Vehicle Compatibility Jeep Wrangler JK 2-Door — 2007–2018 Jeep Wrangler JK Unlimited (4-Door) — 2007–2018 Compatible with hard top, soft top, and dual top configurations Fits factory and most aftermarket sport cage / roll bar upgrades Why Red Matters: The Case for Visibility When smoke starts filling the cabin or you smell burning wiring on the trail, you don't want to be searching for a black bracket in a dark footwell. The red powder-coat finish is instantly recognizable — even in low light, dust, or smoke conditions. It meets the standard color convention for fire safety equipment, making it intuitive for passengers or fellow off-roaders to locate and deploy. Trail Safety Checklist A fire extinguisher is just one piece of a complete off-road safety kit. For maximum trail preparedness, consider pairing this mount with: first aid kit (trauma-focused for remote locations), recovery gear (tow strap, shackles, kinetic rope), tire repair kit and air compressor, emergency communication device (satellite messenger or GMRS radio), and extra water and emergency food rations. Frequently Asked Questions Q: Does the red finish fade in the sun?A: No. Our powder-coating process includes UV-stable pigments designed to resist fading even with years of direct sun exposure. Q: Is the red version the same as the black version?A: Yes — identical construction, materials, and fitment. The only difference is the red powder-coat finish for enhanced visibility. Q: Will this hold a 5lb extinguisher?A: No, this mount is specifically designed for 3lb extinguishers. Using a larger extinguisher may result in an insecure fit. Q: Can I install it behind the driver's seat?A: Yes. The 360-degree adjustable clamp lets you position it in any orientation around the roll bar — behind the driver, passenger, or in the cargo area. Q: Does it rattle on rough roads?A: No. The rubber-lined clamps absorb vibration and the quick-release strap keeps the extinguisher firmly seated even on washboard roads and rock gardens.

Vehicle fires can happen anywhere, but they're especially dangerous on remote trails where emergency services are far away. Common off-road fire hazards include fuel leaks, electrical shorts from aftermarket accessories, overheated brakes igniting dry brush, and catalytic converter contact with tall grass. A properly mounted fire extinguisher gives you critical seconds to respond before a small flame becomes a total loss. Installation Guide Choose your mounting location on the roll bar — driver or passenger side, front or rear Loosen the clamp bolts to open the mounting brackets Position brackets around the roll bar at your desired angle Tighten bolts evenly until the holder is secure — do not overtighten Insert your 3lb fire extinguisher into the cradle and secure the quick-release strap Test that the extinguisher can be removed quickly and easily Frequently Asked Questions Q: Does this come with a fire extinguisher?A: No, this listing is for the mounting bracket only. You'll need a standard 3lb automotive fire extinguisher (sold separately). Q: Will this fit a 4-door JK Unlimited?A: Yes! The roll bar diameter is the same on both 2-door and 4-door (Unlimited) Wrangler JK models from 2007–2018. Q: Can I install this on the driver or passenger side?A: Yes. The mount is fully reversible and 360-degree adjustable — install it wherever provides the quickest access for you. Q: Will this scratch my roll bar?A: No. The clamps feature rubber-lined contact surfaces that protect your roll bar's paint or powder coat finish. Q: Is this legal for on-road use?A: Yes. Carrying a fire extinguisher is legal and recommended in all 50 states. It's also required equipment for many organized off-road events.

  • iFJF Steering Stabilizer Relocation Bracket Replacement for Wrangler JK 2007-2018

    iFJF iFJF Steering Stabilizer Relocation Bracket Replacement for Wrangler JK 2007-2018

    Product Overview The factory steering stabilizer on a JK Wrangler hangs low — right where it meets rocks, logs, and trail obstacles. One solid impact can bend the shaft or tear the mount off, causing death wobble and a ruined trail day. The iFJF Steering Stabilizer Relocation Bracket moves the stabilizer up and out of harm's way. CNC-fabricated from stainless steel with black powder coat, it's a simple, permanent fix that protects one of your steering system's most vulnerable components.

Stainless Steel, Black Powder Coat — High-strength stainless resists rust and corrosion. Black powder coat for clean appearance and chip resistance. LHD Design — Engineered for US-spec left-hand drive JK Wranglers. Bolt-on using existing factory holes — no drilling. Cost-Effective Protection — A bent stabilizer costs $50-100+ to replace. A torn mount requires welding. This bracket prevents both for a fraction of the cost.

That covers virtually everything on the market. Q: Remove stabilizer for install?A: Unbolt from factory mount, install bracket, reattach to new position. ~15-20 minutes with basic tools. Q: Affect steering feel?A: No — the bracket only relocates the mount point. Stabilizer angle, stroke, and damping remain identical. Q: RHD compatible?A: Designed for LHD (US/Canada spec) only. RHD models may have different steering geometry. Q: Needed if I don't rock crawl?A: Even on forest roads, the factory stabilizer is a low-hanging target.

Duramax Maintenance FAQ

How often should I change the fuel filter on a 6.6L Duramax?

GM recommends replacing the Duramax fuel filter every 15,000 to 22,500 miles, or every 12 months. If operating under heavy towing conditions or using biodiesel blends, changing it every 10,000 miles is recommended to protect the high-pressure fuel pump (CP4/HPCR). The L5P models (2017+) use a dual-filter system — both filters should be changed simultaneously for optimal protection.

Are iFJF Duramax filters compatible with OEM housings?

Yes. All iFJF Duramax oil, fuel, and CCV filters are built to exact OEM dimensions. They feature high-grade synthetic filtration media (5-micron rating on fuel filters) to ensure 98%+ water separation efficiency and zero modifications required during installation. Compatible with ACDelco, Racor, and GM factory filter housings.

What causes the "Water in Fuel" warning on my Duramax?

The "Water in Fuel" warning light indicates water accumulation in the fuel filter housing separator. This is common on LML and L5P engines. Drain the water separator immediately using the bleed screw, and consider replacing the filter if the warning persists. Upgrading to an iFJF CNC billet aluminum bleeder screw (replacing the fragile OE plastic screw) prevents stripping and ensures reliable drainage.

Do I need to prime the fuel system after changing a Duramax fuel filter?

For L5P (2017+) models with the electric lift pump, the system self-primes after filter replacement — simply cycle the key to "ON" (without starting) for 30 seconds, repeat 2-3 times. For LB7-LML models, use the manual primer pump on the filter housing until firm resistance is felt. Running the engine without proper priming can cause air in the HPCR system and potential injector damage.

What is the difference between TP1015 and TP3018 Duramax fuel filters?

TP1015 is the spin-on fuel filter used on 2017+ L5P Duramax engines (driver-side frame rail mount). TP3018 is the fuel/water separator filter for 2001-2016 LB7 through LML engines. They are not interchangeable — verify your model year before ordering. iFJF offers both types, including complete kits with upgraded CNC aluminum housing caps.

How do I know if my Duramax fuel filter housing cap needs replacement?

Common signs include: fuel seepage around the cap, difficulty achieving a proper seal after filter changes, cracked or stripped threads on the OE plastic cap, and recurring "Water in Fuel" warnings despite draining. iFJF upgraded CNC 6061-T6 billet aluminum caps (available in multiple colors for the L5P 134001 housing) permanently solve these issues with a precision-machined fit and O-ring sealing surface that outlasts the factory plastic components.
