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.

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.
