Product Description

The FOX 883-26-085 Performance Elite Series 2.5 Piggyback Reservoir Rear Shocks are engineered to enhance the suspension performance of your 2020-2024 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks. These shocks feature a 2.5" impact-extruded and CNC-machined 6061-T6 aluminum body, ensuring superior heat dissipation and consistent damping performance. The external piggyback reservoirs increase oil and nitrogen capacity, reducing shock fade during aggressive off-road driving.

Designed with race-proven technology, these shocks incorporate a high-flow piston design and vehicle-specific valving to deliver optimized ride quality and control. The 7/8" hard chrome-plated heat-treated alloy steel shafts provide maximum strength, while the black-anodized, CNC-machined 6061-T6 billet aluminum components ensure durability. With a lift height compatibility of 0-1", these shocks are suitable for both stock and mildly lifted trucks, offering a bolt-on installation for improved on-road comfort and off-road capability.
