FOX 2.0 Performance Series Reservoir Rear Shock

1984–2001 Jeep Cherokee XJ / 1997–2006 Jeep Wrangler TJ

The FOX Performance Series 2.0 Reservoir Smooth Body Shock delivers FOX’s industry-leading, race-proven performance in an affordable, hassle-free bolt-on package. Built with a metal-impacted clear anodized aluminum body, this shock dissipates heat faster than traditional steel body shocks, helping maintain consistent damping during demanding driving conditions.

Its external reservoir increases oil and nitrogen capacity to further reduce heat buildup while also adding a distinctive race-inspired look. The included black anodized reservoir clamp and mounting components are CNC machined from durable 6061-T6 aluminum for strength and reliability.

Inside, a race-developed high-flow damping piston paired with application-specific valving provides predictable ride quality and improved control, allowing the Performance Series 2.0 Reservoir shock to confidently handle rough roads, trails, and daily driving alike.
