Fox 2.5 Performance Series Coil-Over IFP Front Shock for 2019-2025 GM 1500 (Excl. TrailBoss/AT4, 0–2″ Lift)
FOX Performance Series 2.5 IFP Front Coilover Shocks
2019–2025 Chevy Silverado 1500 & GMC Sierra 1500 | 0–2" Lift
Upgrade your truck’s suspension with the FOX Performance Series 2.5 Coil-Over IFP Shocks. These bolt-on coilovers are engineered with advanced FOX technology to deliver improved ride quality, durability, and front-end leveling. The precision metal impact-extruded aluminum body increases cooling capacity while resisting corrosion, and the vehicle-specific upper mount uses a composite bushing to help isolate noise and vibration for a smoother ride.
Locking spring preload rings allow easy ride height and preload adjustment while retaining a high-quality racing coil spring selected to provide the optimal spring rate. Inside the shock, an Internal Floating Piston (IFP) mono-tube designseparates the shock oil from the high-pressure nitrogen gas chamber to eliminate aeration and maintain consistent damping performance. Designed to bolt on with no modifications, the FOX Performance Series 2.5 Coil-Over IFP shocks provide a comfortable on-road ride with predictable off-road handling—even in demanding conditions.
