Fox 2017+ Ford F250 Super Duty 4-6in Lift Rear 2.5 Performance Series Smooth Body IFP HTO Shock

FOX's latest offering bridges a gap between their entry level 2.0 Performance series shocks and their higher end packages like the 2.5 Factory and Performance-Elite series that come equipped with reservoirs. The Fox HTO (hydraulic top-out) shock features an additional internal piston, positioned between the main working piston and the seal-head of the shock, that acts as a buffer for when the vehicle's suspension fully droops out. This HTO piston is a secondary damping variable in the shock's behavior, recovering the vehicle quicker. Vehicles that see heavier loads, towing, larger wheels & tires, or see a lot of tougher dirt miles will benefit from the Fox HTO 2.5 Performance shocks.
