This is a rear-half fabrication kit — it includes weld-on rear frame brackets, double-adjustable control arms, a 4-link axle truss, and all hardware. The 3-link rear geometry provides maximum axle articulation by eliminating the factory 4-link rear geometry's binding characteristics at extreme suspension travel. The frame-end joints are Currie Johnny Joints — a 3-piece design with a steel ball, Tough 88 urethane casing, and housing that provides 40° of unrestricted movement with the shock absorption and NVH isolation that heim joints cannot provide. The axle-end joints are GIIRO dual-durometer bushings — maintenance-free and self-centering. The double-adjustable control arms allow precise suspension geometry tuning for pinion angle, anti-squat, and arm length. Installation requires welding the rear frame brackets to the LJ frame and fabricating a custom exhaust to clear the new suspension layout. Professional fabrication capability is required. Lifetime warranty on 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-4807017\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eRear 3-Link Long Arm Upgrade Kit — Rear-Half System\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKit Contents\u003c\/td\u003e\n\u003ctd\u003eWeld-On Rear Frame Brackets, Double-Adjustable Control Arms, 4-Link Axle Truss, 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\u003eControl Arms\u003c\/td\u003e\n\u003ctd\u003eDouble-Adjustable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAxle Truss\u003c\/td\u003e\n\u003ctd\u003e4-Link\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstallation\u003c\/td\u003e\n\u003ctd\u003eWelding Required — Weld-On Frame Brackets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExhaust\u003c\/td\u003e\n\u003ctd\u003eCustom Exhaust Required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003eLifetime (Control Arms)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e31 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Dimensions\u003c\/td\u003e\n\u003ctd\u003e32\" x 8\" x 8\"\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 2004–2006 Jeep Wrangler LJ Unlimited — All Trims — Rear 3-Link Long Arm Upgrade Kit\u003cbr\u003e❌ Does NOT fit Jeep Wrangler JK (2007–2018) — different rear frame and suspension architecture\u003cbr\u003e❌ Does NOT fit Jeep Wrangler TJ (1997–2006, 2-Door) — different rear frame dimensions; LJ Unlimited only\u003cbr\u003e❌ Does NOT fit Jeep Wrangler JL (2018–2026) — different rear suspension architecture\u003cbr\u003e❌ Welding required — not a bolt-in kit\u003cbr\u003e❌ Custom exhaust required — factory exhaust not compatible with long arm rear geometry\u003c\/p\u003e\u003ch3\u003eInstallation \u0026amp; Fabrication Notes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWelding required.\u003c\/strong\u003e The rear frame brackets are weld-on — professional fabrication capability or access to a certified welder is required.
