The 5\" stretch extends the rear wheelbase, allowing the use of longer rear control arms that reduce suspension angles more aggressively than a standard-length long arm kit and increase rear axle travel for maximum off-road articulation. The kit includes weld-on rear frame brackets, double-adjustable control arms, a 4-link axle truss, and all hardware. 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 control arms allow precise geometry tuning for pinion angle and anti-squat. Installation requires welding the rear frame brackets to the TJ\/LJ frame, fabricating a custom exhaust to clear the new suspension and stretch geometry, and installing a front CV-style driveshaft with SYE kit. The Clayton D30 front truss is highly recommended. 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-4805302\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eRear Long Arm Upgrade Kit with 5\" Wheelbase Stretch — 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\u003eWheelbase Stretch\u003c\/td\u003e\n\u003ctd\u003e5 Inches — Rear\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\u003eDriveshaft\u003c\/td\u003e\n\u003ctd\u003eFront CV-Style Driveshaft + SYE Kit 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\u003e53 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 1997–2006 Jeep Wrangler TJ (2-Door) — All Trims — Rear Long Arm Upgrade Kit with 5\" Stretch\u003cbr\u003e✅ Fits 2004–2006 Jeep Wrangler LJ Unlimited (4-Door) — All Trims — Rear Long Arm Upgrade Kit with 5\" Stretch\u003cbr\u003e❌ Does NOT fit Jeep Wrangler JK (2007–2018) — different rear frame and suspension architecture\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 5\" stretch long arm geometry\u003cbr\u003e❌ Front CV driveshaft + SYE kit required\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.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom exhaust required.\u003c\/strong\u003e The 5\" stretch and long arm rear geometry require a custom exhaust to clear the new suspension layout.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront CV-style driveshaft and SYE kit required.\u003c\/strong\u003e Source and install before driving after conversion.\u003c\/li\u003e\n\u003cli\u003eInstall the 4-link axle truss to the rear axle before installing the control arms — the truss reinforces the rear axle tube at the control arm mount locations.\u003c\/li\u003e\n\u003cli\u003eWeld the rear frame brackets to the TJ\/LJ frame at the correct locations per Clayton's installation instructions — verify bracket position and angle before final weld-out.\u003c\/li\u003e\n\u003cli\u003eInstall the double-adjustable control arms and set initial length per Clayton's geometry specifications for your lift height and stretch configuration.\u003c\/li\u003e\n\u003cli\u003eSet pinion angle and anti-squat geometry with the vehicle at ride height after full installation.\u003c\/li\u003e\n\u003cli\u003eRear alignment (toe, thrust angle) must be verified after installation.\u003c\/li\u003e\n\u003cli\u003eTorque all control arm hardware at ride height, not at full droop or compression.\u003c\/li\u003e\n\u003cli\u003eInstall the Clayton D30 front truss (highly recommended) before finalizing the front suspension.
