The Fox 2.5 Performance Series Smooth Body IFP Front Shock fits the 2011-2014 GMC Sierra 2500HD and is valved for trucks running 1.5in to 3.5in of front lift.

Aluminum body construction and a true internal floating piston deliver fade-resistant damping on and off road.

Install Difficulty: Professional Install Only
Front shock replacement on an HD truck requires a spring compressor and vehicle lift, takes 2-3 hours per side, and a professional alignment is recommended after any suspension modification.

Product Overview

This is a 2.5in diameter monotube front shock built with an aluminum body, race-developed main piston, and internal floating piston (IFP) that separates gas and oil to resist fade.

Application-specific valving extends drop-out travel for off-road capability while keeping on-road ride connected with less body sway.

Aluminum dissipates heat four times better than steel, and Hydraulic Top Out (HTO) softens the harsh top-out common on lifted HD trucks.
