RS66121BR9

Experience the versatile, purpose-built Rancho® 3.0-inch* Sport suspension system for the Jeep Wrangler JL 2 Door. This new, 100-percent bolt-on system from Rancho Performance Suspension and Shocks allows for the use of up to 35-inch tires for capable, all-around performance. The Sport system also features a NEW Rancho exclusive innovation to the Jeep JL: Rancho® RS5000X shocks with brand-new Dynamic Rebound Spring (DRS) technology. New DRS technology is a unique internal system that includes a precisely tuned metal spring and fortified interior construction to provide additional control, reduce body roll and prevent rod overextension inside the shock. The new system includes a pair of front and rear corner-specific progressive rate coil springs, specifically tuned to provide superior on-road comfort and off-road performance. The corner-specific springs ensure your JL 2 Door maintains a perfectly level stance and ride – even during towing or heavy loading*.

To maintain travel integrity, the Sport system includes front bump stop extensions. Adding lift and extended travel, the system also includes front and rear extended sway bar end links, and an e-brake line relocation bracket. This system is precision engineered to be 100-percent compatible with the Jeep Factory Electronic Stability System. Designed with 35-inch tires. Kit also allows the reuse of OE wheels and tires. Backed by a Limited Lifetime Warranty.
