Rock Krawler X-Factor Mid Arm Suspension Lift Kits
Jeep engineers paid attention to off-roaders when developing the Wrangler models. Their mid-length control arms are longer than stock TJ arms for better articulation. Rock Krawler pushed this concept to the extreme with their bolt-on X-Factor mid arm suspension lift kits. They feature double-adjustable 1.5 in. solid alloy steel track bars with anti-wobble joints, multi-rate long-travel coil springs, and an easy-aligning front upper arms. Pro sway bar disconnects and extended links combine for steadfast highway drives and wicked off-road flex. Rock Krawler X-Factor mid arm suspension lift kits and your own favorite shocks will help get you there and back.
Additional features:
* High-clearance adjustable lower 1.625 in. and upper 1.25 in. control arms, made from solid alloy steel
