Fox 2.0 Performance Series Reservoir Rear Shock (1984–2001 Jeep Cherokee XJ | 1997–2006 Jeep Wrangler TJ | 2–3.5” Lift)

Upgrade your suspension with the proven performance of the FOX 2.0 Performance Series Reservoir Shock. Designed to deliver industry-leading, race-proven performance in an affordable, hassle-free bolt-on package, this shock improves ride quality, control, and durability for both on-road and off-road driving.

The aluminum-bodied Performance Series 2.0 smooth body shock features a metal-impacted clear anodized finish that dissipates heat faster than traditional steel-body shocks, helping maintain consistent performance under demanding conditions. Its external reservoir increases oil and nitrogen capacity, reducing fade while providing a more controlled and predictable ride.

Built with CNC-machined 6061-T6 aluminum components, including a black anodized reservoir clamp, this shock combines durability with a clean, aggressive appearance. The race-developed high-flow damping piston, paired with application-specific valving, delivers a balanced ride quality capable of handling rough terrain, towing, and daily driving with confidence.
