Fox Performance Series 2.5 Smooth Body IFP Front Shock - 0-1 in Lift | 2011-2014 GMC Sierra 3500HD

The Fox 2.5 Performance Series Smooth Body IFP Front Shock fits the 2011-2014 GMC Sierra 3500HD and delivers extended drop-out travel with fade-resistant damping for improved off-road capability and a more connected on-road ride.

Product Overview

This 2.5-inch aluminum-body monotube shock uses a race-developed main piston and a true Internal Floating Piston (IFP) to separate gas and oil, preventing cavitation and fade under heavy use.

The aluminum body dissipates heat four times better than steel, keeping damping consistent on long off-road runs and towing days.

Application-specific valving is tuned for the Sierra 3500HD front end to reduce sway and improve control on and off pavement.
