Fox Performance Series 2.5 Smooth Body IFP Rear Shock - 4-6 in Lift | 2020-2026 GMC Sierra 2500HD

The Fox 2.5 Performance Series Smooth Body IFP Rear Shock fits the 2020-2026 GMC Sierra 2500HD and delivers extended drop-out travel with race-proven damping for lifted trucks.

Product Overview

This is a 2.5-inch diameter monotube rear shock with an aluminum body and a true Internal Floating Piston (IFP) that separates gas and oil for fade-resistant damping.

Fox tunes the valving specifically for the Sierra 2500HD to reduce body sway on-road while extending drop-out travel off-road.

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