Fox 2.0 Performance Series Reservoir Shock (1984–2006 Jeep XJ MJ ZJ WJ TJ Front 2–4.5" Lift)

Upgrade your ride quality and control with the Fox 2.0 Performance Series Reservoir Shock. This aluminum-bodied, smooth body shock delivers FOX’s industry-leading, race-proven performance in an affordable, hassle-free bolt-on package. Its heat-reducing design features a metal-impacted clear anodized aluminum body that dissipates heat faster than traditional steel shocks, while the external reservoir increases oil and nitrogen capacity for improved consistency and performance under demanding conditions. Combined with a race-developed high-flow damping piston and application-specific valving, this shock provides a predictable, controlled ride capable of handling the roughest road and off-road environments.
