Clayton Off Road Front Long Arm Upgrade Kit for 1984-2001 Jeep Cherokee XJ

Is This for You?

• You're running a lifted XJ and want to upgrade from short arm geometry to a long arm system with a 3-piece crossmember, upper and lower adjustable control arms, and Currie Johnny Joints at the frame ends — this front-half long arm upgrade kit replaces the short arm geometry with longer control arms and a 3-piece crossmember, reducing front suspension angles at lift height for a smoother ride and greater articulation.
• You want a crossmember that bolts into the OEM location for alignment, then welds on for maximum strength — with a removable center section for drivetrain service — the 3-piece crossmember uses the OEM bolt locations for initial alignment before welding, ensuring correct positioning. The center section is removable for drivetrain service without removing any suspension components.
• You want Currie Johnny Joints at the frame ends and GIIRO dual-durometer bushings at the axle ends for the best combination of articulation, shock absorption, and maintenance-free on-road comfort — the Currie Johnny Joint provides 40° of unrestricted movement with Tough 88 urethane casing; the GIIRO bushing is pressed into a 5/16" thick housing, free-pivoting, self-lubricating, self-centering, and maintenance-free.

The Result

• Complete front-half long arm upgrade kit — 3-piece crossmember (bolts to OEM location, then welds; removable center section) + upper and lower adjustable control arms and hardware. Full front geometry conversion for the XJ platform.
• Currie Johnny Joints at frame ends (40°, Tough 88 urethane) + GIIRO dual-durometer bushings at axle ends (5/16" housing, free-pivoting, self-lubricating, self-centering, maintenance-free). Lifetime warranty on all control arms.
• Welding required for crossmember. Center section removable for drivetrain service without removing suspension components. For the 3-link front upgrade (6.5"+ lift required), see COR-4801513.

The COR-4801011 is Clayton Off Road's front long arm upgrade kit for the 1984–2001 Jeep Cherokee XJ. The kit includes a 3-piece crossmember and upper and lower adjustable control arms. The 3-piece crossmember is designed to bolt into the OEM crossmember location for alignment purposes before being welded in place for maximum strength — this ensures correct positioning without requiring precise measurement during installation. The center section of the crossmember is removable, allowing drivetrain service without removing any suspension components. 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 pressed into a 5/16" thick housing — free-pivoting, self-lubricating, self-centering, and maintenance-free, providing NVH isolation for on-road comfort and durability for off-road use. The upper and lower control arms are adjustable for precise geometry tuning. Lifetime warranty on all control arms. For the Pro Series 3-link front upgrade (requires minimum 6.5" of lift), see COR-4801513.

Audit Table

Verified Fitment (OFAS Standard)

✅ Fits 1984–2001 Jeep Cherokee XJ — All Trims — Front Long Arm Upgrade Kit
❌ Does NOT fit Jeep Grand Cherokee ZJ (1993–1998) — different front suspension architecture
❌ Does NOT fit Jeep Grand Cherokee WJ (1999–2004) — different front suspension architecture
❌ Does NOT fit Jeep Wrangler TJ/LJ/JK/JL — different platform and front suspension architecture
❌ Welding required for crossmember installation

Installation & Fabrication Notes

• Welding required for crossmember installation — professional fabrication capability or access to a certified welder is required.
• Bolt the 3-piece crossmember into the OEM crossmember location for alignment before welding — the OEM bolt holes provide the correct positioning reference. Do not weld before confirming alignment.
• Weld the crossmember in place after confirming alignment per Clayton's installation instructions.
• The center section of the crossmember is removable after installation — drivetrain service can be performed without removing any suspension components.
• Install the upper and lower adjustable control arms and set initial length 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 XJ wheel and tire combinations. Front long arm geometry affects suspension travel and tire clearance — verify clearance at full droop and full compression with your specific tire size and lift height after installation.

Engineering Question: What is your current lift height on the XJ? If you're running 6.5" or more of lift and want to go further with a 3-link front geometry for maximum articulation, see COR-4801513. Also confirm your front axle — if you're running an aftermarket front axle and plan to add the optional 3-link truss later, note that the 3-link truss (COR-4801513 kit) fits the stock Dana 30 only and will NOT work on aftermarket axles.
