Fox 2.5 Performance Series IFP HTO Rear Shock for 2005-2016 Ford F-250/F-350 (2-3.5" Lift)

Fits select 2005-2016 Ford F-250 and F-350 Super Duty models (XL, XLT, Lariat, King Ranch, Platinum, FX4, Harley-Davidson, Cabela's) with 2-3.5 inches of rear lift.

The FOX 2.5 Performance Series IFP HTO rear shock is engineered to enhance the off-road capability and on-road stability of your Ford Super Duty. The 2.5-inch impact-extruded 6061-T6 aluminum body provides superior heat dissipation compared to traditional steel shocks, ensuring fade-resistant performance during demanding use. This shock features an Internal Floating Piston (IFP) to separate nitrogen gas from the shock oil, preventing aeration and maintaining consistent damping across varied terrain.

Unique to this application is the Hydraulic Top Out (HTO) piston, which acts as a controlled cushion at the end of the rebound stroke. This prevents harsh metal-to-metal contact at full suspension extension, protecting your components during heavy drop-out travel. The high-flow velocity-sensitive damping is specifically tuned for the F-250/F-350 chassis to reduce vehicle sway and provide a more connected ride feel.
