F250 / F350 Super Duty 2017-2025 Ford 4wd (w/2-3.5" lift / Set of 4) - Fox 2.5 Performance Series IFP HTO Shock (FRONT & REAR)

Upgrade your Ford F250/F350 Super Duty with this set of four Fox 2.5 Performance Series Smooth Body HTO Shocks, designed for both front and rear. This kit includes the FOX 987-24-002 and 987-24-003 shock absorbers, providing the ultimate on-road comfort and off-road performance for your Super Duty.

Built with position-sensitive technology and vehicle-specific valving, these shocks deliver outstanding damping control for a smoother, more controlled ride. The 2.5-inch diameter, 6061-T1 anodized aluminum body resists corrosion and efficiently dissipates heat, making it ideal for rigorous conditions. An internal floating piston (IFP) separates shock oil from high-pressure nitrogen, ensuring consistent damping performance under varying loads and speeds. Equipped with Hydraulic top-out (HTO) technology, these shocks reduce harsh top-outs and improve rebound control, an essential feature for trucks with aggressive tires and non-OEM lifts. The secondary shim stack within the shock slows shaft speed to deliver a smooth rebound, enhancing comfort and handling across diverse terrains.
