Product Description

The Rancho RS994330 RS9000XL is a rear shock absorber engineered for 2007-2018 Jeep Wrangler JK and Unlimited JK models (all trims, 4WD) running a 2.5" to 3.5" rear lift. Paired with a compatible Rancho suspension system, it delivers the matching travel length needed to keep the rear suspension properly controlled at lifted ride heights - making it the natural companion to the RS994329 front shock in a complete JK lift shock set.

Built in the 4th-generation RS9000XL design with integrated bottom mounts and a dual 2K chip-resistant paint finish, this shock provides the structural strength and long-term durability demanded by lifted Wrangler use. The 9-position manual adjustment knob allows damping to be dialed in from a soft, trail-compliant setting to a firm highway and towing configuration, and all factory mounting hardware is reused for a direct bolt-on fit.
