The Fox 2.5 Performance Series Smooth Body IFP HTO Shock fits the 2020-2026 GMC Sierra 3500HD front and accommodates 0-1in of front lift while extending drop-out travel for improved off-road articulation.

Install Difficulty: Professional Install Only
Bolts to factory front shock mounts but requires a vehicle lift and suspension disassembly; typically installs in 60-90 minutes per side. Professional alignment recommended after any suspension modification.

Product Overview

This front shock uses an aluminum body, race-developed main piston, and true internal floating piston (IFP) design to separate gas and oil for fade-resistant damping. Application-specific valving delivers on-road comfort with reduced body sway and connected steering feel.

The aluminum construction dissipates heat four times better than steel, and the shock is fully serviceable for a long service life on a heavy-duty truck.
