Clayton Off Road Front Long Arm Upgrade Kit for 1993-1998 Jeep Grand Cherokee ZJ

Is This for You?

• You're running 4–8" of lift on your ZJ and your front short arm geometry is causing harsh ride quality, limited articulation, and accelerated wear on your front control arm bushings — this front-half long arm upgrade kit replaces the short arm geometry with longer control arms and a crossmember, reducing front suspension angles at lift height for a smoother ride and greater articulation. No welding required.
• You want Currie Johnny Joints at the front frame ends and GIIRO dual-durometer bushings at the axle ends — 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're upgrading from a short arm lift or replacing a failing front long arm system and want a complete front-half kit with everything included — this kit includes the crossmember, upper and lower adjustable control arms, and all hardware. No welding required. For the Pro Series 3-link front upgrade with weld-on brackets and a 3-piece crossmember, see COR-4804341.

The Result

• Complete front-half long arm upgrade kit — crossmember, upper and lower adjustable control arms, and hardware. Full front geometry conversion for ZJ builds running 4–8" of lift. No welding required.
• 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.
• Designed for 4–8" of lift. No welding required. For the Pro Series 3-link front upgrade, see COR-4804341.

The COR-4804041 is Clayton Off Road's front long arm upgrade kit for the 1993–2026 Jeep Grand Cherokee ZJ, designed for builds running 4–8" of lift. This is a standard front-half kit — it includes the crossmember, upper and lower adjustable control arms, and all hardware. The longer arm geometry reduces front suspension angles at lift height compared to short arm geometry, resulting in a smoother on-road ride, greater off-road articulation, and reduced wear on related 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 — maintenance-free, self-centering, and NVH-isolating. No welding required. For the Pro Series 3-link front upgrade kit with weld-on brackets, a 3-piece crossmember, and a single upper 3-link arm for maximum articulation, see COR-4804341. Lifetime warranty on all control arms.

Installation & Fabrication Notes

• No welding required for this front long arm upgrade kit.
• Install the crossmember per Clayton's installation instructions before installing the control arms.
• 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 — do not drive without alignment after a long arm conversion.
• Torque all control arm hardware at ride height, not at full droop or compression.
• Verify front driveshaft angle and U-joint operating angles after installation.
• If upgrading to a 3-link front geometry at the same time, see COR-4804341 for the Pro Series 3-link kit.

Wheel & Tire Fitment

Compatible with standard ZJ wheel and tire combinations at 4–8" of lift. 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: What is your current lift height on the ZJ? This kit is designed for 4–8" of lift. If you want to go further and convert to a 3-link front geometry for maximum articulation, see COR-4804341 (Pro Series 3-link kit with weld-on brackets and 3-piece crossmember). Also confirm your vehicle is a 1993–1998 Grand Cherokee ZJ — this kit does not fit the WJ (1999–2004) or WK (2005–2010) platforms.
