The Fox 2.5 Performance Series Smooth Body IFP Rear Shock fits the 2015-2019 Chevy Silverado 3500HD and delivers race-developed damping for lifted HD trucks running 4-6in of rear lift.

Bolts to factory rear shock mounts with hand tools; typically installs in 45-60 minutes per side. Professional alignment recommended after any suspension modification.

Product Overview

This is a monotube rear shock with an aluminum body, race-developed main piston, and a true internal floating piston (IFP) that separates gas and oil for fade-free performance.

Tuned for HD trucks with 4-6in of rear lift, it extends drop-out travel off-road while cutting sway on the highway.

Aluminum dissipates heat roughly 4x better than steel, and the shock is fully serviceable for a long service life.
