🧾 Overview
The FOX Performance Series 2.0 Reservoir Rear Shocks are engineered to significantly improve ride quality, control, and heat management on Jeep Cherokee and Wrangler TJ platforms—both on-road and off. Featuring an external reservoir, these shocks increase oil and nitrogen capacity to reduce heat during rapid suspension cycling, delivering consistent, fade-free performance in demanding conditions.
Built with a 6061-T6 aluminum body and race-developed high-flow piston, the 2.0 Reservoir shocks use application-specific valving to balance comfort and off-road capability. Tunability is a standout feature, offering nitrogen pressure adjustments, compression and rebound valving, and 8 clicks of compression adjustability to tailor performance to your setup and driving style.
