The Fox 2.5 Performance Series Smooth Body IFP Shock fits the 2015-2019 Chevy Silverado 3500HD and delivers race-developed damping for trucks with 1.5-3.5in of front lift.

Install Difficulty: Professional Install Only
Front shock replacement on a 3500HD requires a vehicle lift and typically takes 60-90 minutes per side. Professional alignment recommended after any suspension modification.

Product Overview

This front shock uses a 2.5in aluminum body, a race-developed main piston, and a true Internal Floating Piston (IFP) that separates gas and oil to resist fade.

Application-specific valving extends drop-out travel off-road while controlling sway on-road. Aluminum construction dissipates heat four times better than steel and remains fully serviceable.
