Fox 2.0 Performance Series Smooth Body IFP Rear Shock (13.1in Travel) for 1999-2019 Select GM HD & Hummer H2 (7-10in Lift)

Fits select 1999-2019 Chevrolet Silverado/GMC Sierra 1500HD, 2500/HD, 3500/HD, Suburban/Yukon XL 2500, Avalanche 2500, and 2003-2009 Hummer H2.

The Fox 2.0 Performance Series Smooth Body IFP (Internal Floating Piston) rear shock provides industry-leading performance for vehicles equipped with a 7-10 inch lift. Constructed with a 2.0-inch metal-impacted 6061-T6 aluminum body, this shock dissipates heat four times faster than conventional steel shocks, preventing fade during extended off-road use. The internal floating piston architecture separates the shock oil from the high-pressure nitrogen gas chamber, eliminating oil aeration and ensuring consistent damping control over washboards or technical terrain.

Built for durability and long-term service, these shocks feature a redundant sealing system to protect against the elements and Teflon-lined, heat-treated spherical bearings for smooth articulation. Every unit is 100% serviceable and tunable, allowing for a lifetime of use. This shock is specifically valved to reduce vehicle sway and improve on-road comfort while maximizing drop-out travel for off-road capability.
