FOX Performance Series 2.5 Smooth Body IFP Front Shock - 4-6 in Lift | 2011-2014 GMC Sierra 2500HD

The Fox 2.5 Performance Series Smooth Body IFP Front Shock fits the 2011-2014 GMC Sierra 2500HD and is valved for trucks running 4-6in of front lift.

Extended drop-out travel and race-developed valving deliver off-road capability with on-road comfort.

Product Overview

This 2.5in diameter monotube shock uses an aluminum body and true internal floating piston (IFP) to separate gas and oil, preventing fade under repeated hits.

Aluminum construction dissipates heat four times better than steel, keeping damping consistent on long trails or washboard roads.

Fully serviceable and rebuildable, so the shock delivers a lifetime of performance rather than a one-time replacement.
