Product Description

The FOX 883-26-087 Performance Elite Series 2.5 Rear Adjustable Reservoir Shocks are engineered for lifted Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. Designed to fit rear suspension setups with a 2.5-4" lift, these shocks provide improved ride control, heat management, and suspension performance compared to stock units. Dual Speed Compression (DSC) adjustability lets you fine-tune both high and low speed compression to match weight, terrain, and driving style, delivering a balanced ride on pavement and off-road.

Constructed with a CNC-machined aluminum body and a high-flow piston, the 883-26-087 delivers consistent damping performance while resisting corrosion and wear. The external reservoir increases oil and nitrogen capacity, reducing fade during extended use and improving performance under load. Ideal for truck owners seeking a performance enhancement for lifted rear suspension setups, these shocks enhance control, comfort, and handling for daily driving and trail use alike.
