Description

2001–2019 Chevy Silverado & GMC Sierra 2500HD/3500HD Rear Fox Performance Series 2.0 Reservoir Shock

Upgrade your suspension performance with the Fox Performance Series 2.0 Reservoir Shock, designed to deliver consistent damping, improved ride control, and race-proven reliability in a hassle-free bolt-on package. Built for both daily driving and aggressive off-road use, this shock provides the performance and durability Fox is known for.

The aluminum-bodied Performance Series 2.0 Reservoir smooth body shock delivers FOX’s industry-leading, race-dominating performance at an affordable price point. Its heat-reducing design features a metal-impact clear anodized aluminum shock body that dissipates heat faster than traditional steel-bodied shocks, helping maintain consistent performance under demanding conditions.

An external reservoir increases oil and nitrogen capacity, improving cooling and damping consistency while adding a clean, race-inspired look. The included black anodized reservoir mounting clamp and components are CNC machined from 6061-T6 aluminum for strength and precision. Inside, a race-developed high-flow damping piston paired with application-specific valving delivers a predictable ride quality capable of handling even the roughest terrain.
