Clayton Off Road Pro Series Front 3-Link Long Arm Upgrade Kit for 2004-2006 Jeep Wrangler LJ Unlimited

Is This for You?

• You're building a complete front long arm system on your LJ Unlimited and want a 3-link geometry from the ground up — not a conversion add-on — this is the complete front-half Pro Series 3-link long arm upgrade kit: front frame brackets, weld-on 3-link upper arm mount brackets, double-adjustable lower control arms, upper 3-link arm with LH/RH threads, and all hardware. Everything needed for the front-half geometry conversion in one kit.
• You want Currie Johnny Joints at the frame ends and GIIRO dual-durometer bushings at the axle ends on both the upper and lower arms — the Currie Johnny Joint provides 40° of unrestricted movement with Tough 88 urethane casing for shock absorption and NVH isolation that heim joints cannot match; the GIIRO bushing at the axle end is maintenance-free, self-centering, and NVH-isolating for on-road comfort.
• 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 frame brackets and 3-link upper mount 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

• Complete front-half Pro Series 3-link long arm upgrade kit — front frame brackets, weld-on 3-link upper arm mount brackets, double-adjustable lower control arms, upper 3-link arm (LH/RH threads), and hardware. Full front geometry conversion for the LJ platform.
• Currie Johnny Joints at frame ends (40°, Tough 88 urethane) + GIIRO dual-durometer bushings at axle ends — maintenance-free, NVH-isolating, self-centering. Lifetime warranty on all control arms.
• Welding required. Custom exhaust required. Front CV driveshaft + SYE kit required. Clayton D30 front truss highly recommended. Aftermarket axles require custom truss.

The COR-4807013 is Clayton Off Road's Pro Series complete front 3-link long arm upgrade kit for the 2004–2006 Jeep Wrangler LJ Unlimited. Unlike the COR-4807015 conversion add-on (which upgrades an existing long arm system to 3-link), this kit is the complete front-half system — it includes the front frame brackets, weld-on 3-link upper arm mount brackets, double-adjustable lower control arms, upper 3-link arm with LH/RH threads, and all hardware. 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 frame-end joints are Currie Johnny Joints — 40° of unrestricted movement with Tough 88 urethane casing for shock absorption and NVH isolation. The axle-end joints are GIIRO dual-durometer bushings — maintenance-free, self-centering, and NVH-isolating. The double-adjustable lower control arms allow precise geometry tuning for caster and arm length. The upper 3-link arm uses LH/RH threads for quick length adjustment without removing the arm. Installation requires welding the frame brackets and 3-link upper mount, fabricating a custom exhaust, 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 upper arm mount location. Aftermarket axles require a truss compatible with your specific axle. Lifetime warranty on all control arms.

Verified Fitment (OFAS Standard)

✅ Fits 2004–2006 Jeep Wrangler LJ Unlimited — All Trims — Complete Front 3-Link Long Arm Upgrade Kit
❌ Does NOT fit Jeep Wrangler TJ (1997–2006, 2-Door) — LJ Unlimited only
❌ Does NOT fit Jeep Wrangler JK (2007–2018) — different front suspension architecture
❌ Does NOT fit Jeep Wrangler JL (2018–2026) — different front suspension architecture
❌ Welding, custom exhaust, front CV driveshaft + SYE kit required — not a bolt-in kit
❌ If you only need the 3-link upper arm conversion add-on, see COR-4807015

Installation & Fabrication Notes

• Welding required. The front frame brackets and 3-link upper arm mount brackets are weld-on — professional fabrication capability or access to a certified welder is required.
• Custom exhaust required. The 3-link front long arm geometry requires a custom exhaust to clear the new suspension 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-side upper arm 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 front frame brackets and 3-link upper arm mount brackets per Clayton's installation instructions — verify position and angle before final weld-out.
• Install the double-adjustable lower control arms and upper 3-link arm; set initial lengths per Clayton's geometry specifications for your lift height.
• Set caster and pinion angle with the vehicle at ride height after full installation.
• Front alignment (caster, toe) must be verified after installation.
• Torque all control arm hardware at ride height, not at full droop or compression.

Wheel & Tire Fitment

Compatible with standard LJ wheel and tire combinations. 3-link front long arm 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 building a complete front long arm system from scratch, or converting an existing long arm setup to 3-link? If you already have a long arm system and only need the 3-link upper arm conversion, order COR-4807015 instead. Also confirm you have a front CV driveshaft with SYE kit sourced, access to a certified welder, a plan for the custom exhaust, and a D30 front truss (or compatible aftermarket axle truss) before ordering.
