Fox Performance Series 2.5 Smooth Body IFP HTO Front Shock, 0-1" Lift for 2020-2026 Chevy/GMC 2500/3500 HD

Fits 2020-2026 Chevrolet Silverado and GMC Sierra 2500 HD/3500 HD models (All Trims).

Designed to enhance the off-road capability of your heavy-duty truck, the Fox Performance Series 2.5 Smooth Body shock utilizes advanced damping technology to increase drop-out travel and maintain precise control. These shocks are engineered to provide a connected on-road feel with significantly reduced vehicle sway, while the application-specific valving ensures optimal performance for the Chevy/GMC HD chassis. The 2.5-inch impact-extruded aluminum body dissipates heat four times faster than conventional steel shocks, preventing fade during extended use.

Each shock features a race-developed high-flow piston and an Internal Floating Piston (IFP) to separate the nitrogen charge from the shock oil, ensuring consistent, aeration-free damping. The addition of the Hydraulic Top Out (HTO) piston provides a smooth deceleration at the end of the extension stroke. These units are fully rebuildable and re-tunable, providing a long-term suspension solution for both work and play.
