2.5 Performance Series Rear Shock Absorber

The Fox 987-24-028 Performance Series 2.5 Smooth Body IFP Shock is engineered to enhance the driving dynamics of your 2019+ Chevrolet Silverado 1500. Its application-specific valving is tailored to maximize performance, offering a blend of a comfortable on-road ride and predictable off-road handling. Constructed with a 2.5-inch impact-extruded 6061-T6 aluminum shock body and Type II clear-anodized plating, this shock is built for durability and corrosion resistance. Key internal components include a high-flow, velocity-sensitive damping system, a 5/8-inch hard chrome shaft, and an internal floating piston (IFP) for consistent damping control. The shock is fully rebuildable and re-tunable, ensuring longevity and the ability to adjust performance characteristics. This shock absorber has a compressed length of 17.69 inches and an extended length of 27.75 inches, with 10.06 inches of travel. It features ES7 mounts on both the top and bottom. The shock is specifically tuned for the GM 1500 platform, with detailed fitment notes indicating applications for trucks with 2.5-4 inch lifts (requiring a 2-inch bump spacer) and TB/AT4 models with 0-2 inch lifts.
