Fox Performance Series 2.5 Smooth Body IFP Rear Shock - 4-6 in Lift | 2011-2014 GMC Sierra 3500HD

The Fox 2.5 Performance Series Smooth Body IFP Rear Shock fits the 2011-2014 GMC Sierra 3500HD and delivers extended drop-out travel with fade-resistant damping for lifted trucks.

Product Overview

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

Application-specific valving delivers on-road comfort with less body sway, while extended travel supports 4-6in of rear lift on your Sierra 3500HD.

The aluminum body dissipates heat four times better than steel and the shock is fully serviceable for a long service life.
