The Fox 2.5 IFP Front Shock fits the 2020-2026 GMC Sierra 2500HD with 6.5in of front lift and delivers race-developed damping for lifted heavy-duty trucks.

Install Difficulty: Professional Install Only
Front shock replacement on a lifted HD truck requires a vehicle lift and suspension disassembly, typically takes 2-3 hours per side, and a post-install alignment is required.

Product Overview

This is a 2.5in-diameter aluminum-body front shock built with an internal floating piston (IFP) that separates gas and oil for fade-free performance.

The application-specific valving extends drop-out travel off-road while keeping the ride connected and controlled on pavement.

Aluminum construction dissipates heat four times better than steel, and the shock is fully serviceable for long service life on your lifted Sierra 2500HD.
