FOX Performance Series 2.5 Smooth Body IFP Front Shock - 4-6 in Lift | 2015-2019 GMC Sierra 2500HD

The Fox 2.5 Performance Series Smooth Body IFP Front Shock fits the 2015-2019 GMC Sierra 2500HD and is valved for trucks running 4-6in of front lift.

It delivers race-developed damping with fade-resistant performance for on- and off-road use.

Product Overview

This monotube shock uses an aluminum body and a true internal floating piston (IFP) to separate gas and oil, preventing cavitation under hard use.

The race-developed main piston and application-specific valving extend drop-out travel off-road while reducing sway on the street. Aluminum dissipates heat four times better than steel, keeping damping consistent on long trails.

Fully serviceable and corrosion-resistant for a long service life on lifted HD trucks.
