Built using FOX's race-proven suspension technology, this premium monotube shock delivers exceptional ride quality, improved control, and outstanding durability both on and off the road.

Construction & Design
FOX constructs the Performance Series 2.0 Reservoir Shock using a lightweight 6061-T6 impact-extruded aluminum body, which dissipates heat much more efficiently than conventional steel-body shocks. The external reservoir increases fluid volume and nitrogen capacity, while the Internal Floating Piston keeps the shock oil separated from the nitrogen charge to eliminate aeration and provide consistent damping. Premium billet aluminum components, a hard chrome-plated alloy steel shaft, and FOX's redundant sealing system ensure exceptional durability in demanding conditions.
Driving Feel & Feedback
Whether you're towing a heavy trailer, hauling equipment, or navigating rough trails, the FOX Performance Series 2.0 Reservoir Shock provides improved steering control, reduced front-end dive, and greater suspension stability. The race-developed high-flow piston and vehicle-specific valving deliver a smooth, predictable ride while the external reservoir helps prevent shock fade during extended off-road driving and heavy-duty use. The result is increased driver confidence both on the highway and off the beaten path.
