Construction & Design
The Performance Series 2.0 Reservoir Shock utilizes a lightweight 6061-T6 aluminum monotube body that dissipates heat significantly faster than conventional steel-body shocks while resisting corrosion. The external reservoir increases fluid volume, reducing operating temperatures and minimizing shock fade during prolonged use. FOX's race-developed high-flow piston and vehicle-specific valving provide exceptional ride quality, while premium seals and billet aluminum components ensure long-lasting reliability.
Driving Feel & Feedback
Whether you're towing heavy trailers, hauling equipment, or tackling rough terrain, the FOX Performance Series 2.0 Reservoir Rear Shock delivers exceptional control and confidence. The additional fluid capacity provided by the external reservoir allows the shock to maintain consistent damping under demanding conditions, resulting in improved stability, reduced body movement, and a smoother ride over washboard roads, rocky trails, and uneven terrain.
