The Fox 2.5 Performance Series Smooth Body IFP Front Shock fits the 2020-2026 Chevy Silverado 3500HD and is tuned for trucks running 4-6in of front lift. It extends drop-out travel for off-road capability while maintaining on-road comfort.

Install Difficulty: Professional Install Only
Front shock replacement on a 3500HD requires a vehicle lift and heavy-duty spring tooling, typically 2-3 hours per side. Professional alignment recommended after any suspension modification.

Product Overview

This 2.5in diameter monotube shock uses an aluminum body and race-developed main piston with a true Internal Floating Piston (IFP) that separates gas and oil for fade-resistant damping.

Aluminum construction dissipates heat four times better than steel, and every Fox shock is fully serviceable and corrosion-resistant.

Vehicle-specific valving reduces body sway and delivers a connected ride on lifted 3500HDs.
