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.\u003c\/p\u003e\u003ch3\u003eAudit Table\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eCOR-4804341\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eComplete Front 3-Link Long Arm Upgrade Kit — Front-Half System\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKit Contents\u003c\/td\u003e\n\u003ctd\u003eWeld-On 3-Link Upper Arm Mount Brackets, Double-Adjustable Lower Control Arms, Upper 3-Link Arm (LH\/RH Threads), 3-Piece Crossmember, Hardware\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrame-End Joint\u003c\/td\u003e\n\u003ctd\u003eCurrie Johnny Joint — 40° Movement, Tough 88 Urethane Casing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAxle-End Joint\u003c\/td\u003e\n\u003ctd\u003eGIIRO Dual-Durometer Bushing — Maintenance-Free, NVH-Isolating, Self-Centering\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLower Arms\u003c\/td\u003e\n\u003ctd\u003eDouble-Adjustable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUpper Arm\u003c\/td\u003e\n\u003ctd\u003eSingle 3-Link, LH\/RH Threads\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrossmember\u003c\/td\u003e\n\u003ctd\u003e3-Piece\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstallation\u003c\/td\u003e\n\u003ctd\u003eWelding Required — Weld-On 3-Link Upper Arm Mount Brackets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExhaust\u003c\/td\u003e\n\u003ctd\u003eCustom Exhaust Required — Must Clear Upper 3-Link Arm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDriveshaft\u003c\/td\u003e\n\u003ctd\u003eFront CV-Style Driveshaft Required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFront Axle Truss\u003c\/td\u003e\n\u003ctd\u003eClayton D30 Front Truss Highly Recommended; Aftermarket Axles Require Custom Truss\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003eLifetime (All Control Arms)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e33 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Dimensions\u003c\/td\u003e\n\u003ctd\u003e28\" x 6\" x 6\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eVerified Fitment (OFAS Standard)\u003c\/h3\u003e\u003cp\u003e✅ Fits 1993–1998 Jeep Grand Cherokee ZJ — All Trims — Complete Front 3-Link Long Arm Upgrade Kit\u003cbr\u003e❌ Does NOT fit Jeep Grand Cherokee WJ (1999–2004) — different front suspension architecture\u003cbr\u003e❌ Does NOT fit Jeep Grand Cherokee WK (2005–2010) — different front suspension architecture\u003cbr\u003e❌ Does NOT fit Jeep Wrangler TJ\/LJ\/JK\/JL — different platform and front suspension architecture\u003cbr\u003e❌ Welding, custom exhaust (upper 3-link arm clearance), front CV driveshaft required — not a bolt-in kit\u003c\/p\u003e\u003ch3\u003eInstallation \u0026amp; Fabrication Notes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWelding required.\u003c\/strong\u003e The 3-link upper arm mount brackets are weld-on — professional fabrication capability or access to a certified welder is required.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom exhaust required to clear the upper 3-link arm.\u003c\/strong\u003e The upper 3-link arm routing requires exhaust modification or a custom exhaust — plan and fabricate before final installation of the upper arm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront CV-style driveshaft required.\u003c\/strong\u003e Source and install before driving after conversion.\u003c\/li\u003e\n\u003cli\u003eInstall 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.
