Fox 2.5 Performance Series IFP HTO Rear Shock for 2005-2016 Ford F-250/F-350 Super Duty (0-1.5" Lift)

Fits 2005-2016 Ford F-250 and F-350 Super Duty models with 0-1.5 inches of rear lift.

The Fox 2.5 Performance Series IFP HTO rear shock is engineered to provide professional-grade damping and control for your Super Duty. Its 2.5-inch impact-extruded 6061-T6 aluminum body dissipates heat up to four times faster than traditional steel shocks, ensuring consistent, fade-resistant performance even under heavy loads. The Internal Floating Piston (IFP) technology separates the shock oil from the high-pressure nitrogen gas chamber, eliminating oil aeration and foaming for a more connected and stable ride.

This HTO (Hydraulic Top Out) model features a specialized internal piston designed to manage the shock's extension, significantly reducing harshness when the suspension reaching full travel. Fully rebuildable and re-tunable, this shock is designed for long-term durability in harsh environments.
