The Fox 2.5 Performance Series Shock fits the 2020-2026 GMC Sierra 2500HD and extends drop-out travel for improved off-road capability with vehicle-tuned valving.
Product Overview
This is a 2.5in aluminum-body monotube shock with a race-developed main piston and a true internal floating piston (IFP) that separates gas and oil for fade-resistant damping.
The aluminum body dissipates heat four times better than steel, keeping performance consistent under repeated hits. Valving is tuned specifically for the Sierra 2500HD to reduce body sway and deliver a connected on-road ride.
Fully serviceable and built to resist corrosion in harsh environments.
