Clayton Off Road Pro Series Front 3-Link Long Arm Conversion Kit for 1997-2006 Jeep Wrangler TJ and LJ Unlimited

Is This for You?

• You're already running a long arm system on your TJ or LJ and want to convert the front to a 3-link geometry for maximum articulation — this is an upgrade conversion kit, not a complete long arm kit. It adds a single upper 3-link arm with 1/4" weld-on frame and axle mounts to your existing long arm setup, converting the front from a 4-link to a 3-link geometry for increased axle articulation and reduced binding at extreme suspension travel.
• You want a Currie Johnny Joint at the frame end and a GIIRO bushing at the axle end on the upper 3-link arm, with LH/RH threads for quick length adjustment — the upper arm uses a Currie Johnny Joint at the frame end (40° movement, Tough 88 urethane casing) and a GIIRO dual-durometer bushing at the axle end, with LH/RH threads for arm length adjustment without removing the arm.
• You understand this is a fabrication-level install requiring welding, a custom exhaust, a front CV driveshaft with SYE kit, and a D30 front truss — the 1/4" frame and axle mounts are weld-on, the long arm geometry requires a custom exhaust, and a front CV driveshaft with SYE kit is required. The Clayton D30 front truss is highly recommended. Aftermarket axles require sourcing a truss specific to your axle.

The Result

• Front 3-link conversion add-on — 1/4" weld-on frame mount, 1/4" weld-on axle mount, and single upper 3-link arm with LH/RH threads. Converts existing TJ/LJ long arm front from 4-link to 3-link geometry for maximum articulation.
• Currie Johnny Joint at frame end (40°, Tough 88 urethane) + GIIRO dual-durometer bushing at axle end — maintenance-free, NVH-isolating, self-centering at the axle mount.
• Lifetime warranty on control arm. Welding required. Custom exhaust required. Front CV driveshaft + SYE kit required. Clayton D30 front truss highly recommended.

The COR-4805015 is Clayton Off Road's Pro Series front 3-link long arm conversion kit for the 1997–2006 Jeep Wrangler TJ and LJ Unlimited. This is an upgrade conversion kit for TJ/LJ builds already running a long arm system — it is not a complete long arm kit. The kit adds a single upper 3-link arm with 1/4" weld-on frame and axle mounts, converting the front suspension from a 4-link to a 3-link geometry. The 3-link front geometry eliminates the binding characteristics of the factory 4-link upper arm arrangement at extreme suspension travel, providing maximum axle articulation for hardcore off-road use. The upper arm uses a Currie Johnny Joint at the frame end — 40° of unrestricted movement with Tough 88 urethane casing for shock absorption and NVH isolation — and a GIIRO dual-durometer bushing at the axle end. LH/RH threads allow arm length adjustment without removing the arm. Installation requires welding the 1/4" frame and axle mounts, fabricating a custom exhaust to clear the new geometry, and installing a front CV-style driveshaft with SYE kit. The Clayton D30 front truss is highly recommended to reinforce the front axle at the new upper arm mount location. Aftermarket axles require sourcing a truss compatible with your specific axle. Lifetime warranty on the control arm. TJ equivalent of COR-4807015 (LJ-specific version).

Audit Table

Verified Fitment (OFAS Standard)

✅ Fits 1997–2006 Jeep Wrangler TJ (2-Door) — All Trims — Front 3-Link Conversion, Existing Long Arm System Required
✅ Fits 2004–2006 Jeep Wrangler LJ Unlimited (4-Door) — All Trims — Front 3-Link Conversion, Existing Long Arm System Required
❌ Does NOT fit Jeep Wrangler JK (2007–2018) — different front suspension architecture; see COR-4807015 for LJ or COR-4808122 for JK
❌ Does NOT fit Jeep Wrangler JL (2018–2026) — different front suspension architecture
❌ Not a complete long arm kit — requires existing long arm system on the TJ or LJ
❌ Welding, custom exhaust, front CV driveshaft + SYE kit required — not a bolt-in conversion

Installation & Fabrication Notes

• Welding required. The 1/4" frame and axle mounts are weld-on — professional fabrication capability or access to a certified welder is required.
• Custom exhaust required. The 3-link front geometry requires a custom exhaust to clear the new upper arm and mount layout.
• Front CV-style driveshaft and SYE kit required. Source and install before driving after conversion.
• Install the Clayton D30 front truss (highly recommended) before welding the axle mount — the truss reinforces the front axle tube at the new upper arm mount location. Aftermarket axles require a truss specific to your axle.
• Weld the 1/4" frame mount and axle mount per Clayton's installation instructions — verify position and angle before final weld-out.
• Install the upper 3-link arm and set initial length using the LH/RH thread adjustment.
• Set caster and pinion angle with the vehicle at ride height after full installation.
• Front alignment (caster, toe) must be verified after installation.

Wheel & Tire Fitment

Compatible with standard TJ/LJ wheel and tire combinations. 3-link front geometry affects suspension travel and tire clearance — verify clearance at full droop and full compression with your specific tire size after installation.

Engineering Question: Are you already running a long arm system on your TJ or LJ? This is a conversion add-on kit — it requires an existing long arm setup to convert from 4-link to 3-link front geometry. Also confirm you have a front CV driveshaft with SYE kit sourced, access to a certified welder for the weld-on mounts, and a plan for the custom exhaust before ordering. If you're running aftermarket axles, source a compatible front axle truss before installation.
