Fox 05-16 Ford Super Duty 2-3.5in Lift Rear 2.5 Perf. Series IFP HTO Shock

FOX is known for making suspension components that perform well both on the pavement and when you take your truck off-road. These rear shocks are built specifically for your 2005-2016 Ford F-250 Super Duty, especially if you've added a 2 to 3.5-inch lift kit. They use race-proven damping technology to give you a more comfortable ride when you're just driving around town, but they also handle tough off-road conditions predictably.

The shock body is made from impact-extruded 6061-T6 aluminum, which is strong and corrosion-resistant thanks to its Type II clear-anodized plating. Inside, a high-flow, velocity-sensitive damping system works with the internal floating piston (IFP) and the Hydraulic Top Out (HTO) piston to manage fluid flow and prevent cavitation. This setup is application-specific, meaning the valving is tuned to work best with your Super Duty's weight and suspension travel. The 5/8-inch hard chrome shaft adds durability and resistance to wear.

These shocks are also fully rebuildable and re-tunable, so you can service them down the road to maintain their performance. They are designed to fit right and work with your lifted truck's geometry.
