Clayton Off Road Pro Series Front 3-Link Long Arm Upgrade Kit for 1993-1998 Jeep Grand Cherokee ZJ

Is This for You?

• You're building a serious long-arm front suspension on your ZJ and want a complete Pro Series 3-link geometry kit with a 3-piece crossmember, double-adjustable lower arms, and a single upper 3-link arm — this is the complete front-half Pro Series 3-link long arm upgrade kit for the 1993–1998 Jeep Grand Cherokee ZJ: weld-on 3-link upper arm mount brackets, double-adjustable lower control arms, upper 3-link arm with LH/RH threads, 3-piece crossmember, and all hardware.
• 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; 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 to clear the upper 3-link arm, a front CV driveshaft, and a D30 front truss — the 3-link upper arm mount brackets are weld-on, the upper 3-link arm requires a custom exhaust for clearance, and a front CV driveshaft 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 — weld-on 3-link upper arm mount brackets, double-adjustable lower control arms, upper 3-link arm (LH/RH threads), 3-piece crossmember, and hardware. Full front 3-link geometry conversion for the ZJ 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 to clear upper 3-link arm. Front CV driveshaft required. Clayton D30 front truss highly recommended.

The COR-4804341 is Clayton Off Road's Pro Series complete front 3-link long arm upgrade kit for the 1993–1998 Jeep Grand Cherokee ZJ. The kit includes weld-on 3-link upper arm mount brackets, double-adjustable lower control arms, upper 3-link arm with LH/RH threads, a 3-piece crossmember, and all hardware. The 3-link front geometry eliminates the binding characteristics of the factory ZJ 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 3-link upper arm mount brackets, fabricating a custom exhaust specifically to clear the upper 3-link arm, and installing a front CV-style driveshaft. 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 1993–1998 Jeep Grand Cherokee ZJ — All Trims — Complete Front 3-Link Long Arm Upgrade Kit
❌ Does NOT fit Jeep Grand Cherokee WJ (1999–2004) — different front suspension architecture
❌ Does NOT fit Jeep Grand Cherokee WK (2005–2010) — different front suspension architecture
❌ Does NOT fit Jeep Wrangler TJ/LJ/JK/JL — different platform and front suspension architecture
❌ Welding, custom exhaust (upper 3-link arm clearance), front CV driveshaft required — not a bolt-in kit

Installation & Fabrication Notes

• Welding required. The 3-link upper arm mount brackets are weld-on — professional fabrication capability or access to a certified welder is required.
• Custom exhaust required to clear the upper 3-link arm. The upper 3-link arm routing requires exhaust modification or a custom exhaust — plan and fabricate before final installation of the upper arm.
• Front CV-style driveshaft 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.
• Install the 3-piece crossmember per Clayton's installation instructions before installing the control arms.
• Weld the 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 ZJ 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 and lift height after installation.

Engineering Question: Have you confirmed your exhaust routing plan before ordering? The upper 3-link arm requires a custom exhaust specifically for clearance — this is not a minor modification. Also confirm you have a front CV driveshaft sourced and access to a certified welder for the weld-on brackets. If you're running aftermarket axles, source a compatible front axle truss before installation.
