The NEW RS66114B Crawler Short Arm Kit is the result of continuous improvements done by Rancho to give you the best possible on and off-road experience for your JK. The kit includes progressive rate coil springs and fully adjustable control arms with D2 bushings to give you improved comfort, durability and worry free operation. This kit also features our new heavy-duty front and rear adjustable track bars with D2 bushings to center the axles. The D2 bushings found in our control arms and track bars feature PTFE for grease-free operation allowing the sleeve to rotate in the bushing without resistance reducing wear. Exhaust cross over pipe RS720003 is required for (2018-12) when not replacing the front driveshaft. The RS66114B supersedes our RS66104 and RS66104B kits. The Rancho brand offers a Limited Lifetime Warranty** for this suspension system.
