Experience the versatile, purpose-built Rancho 3.5-in. Sport Suspension System for the Jeep Wrangler JL Unlimited Non-Rubicon. 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 RS9000™XL 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 Unlimited maintains a perfectly level stance and ride – even during towing or heavy loading. To maintain travel integrity, the Sport System includes front 3-inch and rear 2-inch bump stop extensions. Adding lift and extended travel, the system also includes front sway bar adapter brackets, 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 and 17-inch wheels with 4.5-inch of backspacing. Kit also allows the reuse of OE wheels and tires. Backed by a Limited Lifetime Warranty.
