The Fox 2.5 Performance Series Smooth Body IFP Shock fits the 2015-2019 Chevy Silverado 3500HD front and is valved for trucks running 4-6in of front lift.

It delivers extended drop-out travel off-road and controlled, low-sway handling on the highway.

Install Difficulty: Professional Install Only
Front shock replacement on a 3500HD requires a vehicle lift and suspension disassembly, typically taking 1-2 hours per side. Professional alignment recommended after any suspension modification.

Product Overview

This 2.5in diameter aluminum-body monotube shock uses a race-developed main piston and a true Internal Floating Piston (IFP) to separate gas and oil, eliminating foaming and fade under sustained abuse.

The aluminum body dissipates heat up to four times faster than steel, keeping damping consistent across long trails and washboard runs. Application-specific valving is tuned for the 3500HD chassis to reduce vehicle sway while preserving ride comfort.

Fully serviceable and rebuildable for a long service life.
