2014–2026 Ram 2500 Rear Fox 2.5 Performance Series HTO Shocks (2–3” Lift)

Upgrade your ride quality and control with the Fox 2.5 Performance Series HTO Rear Shock, engineered specifically for Ram 2500 trucks running a 2–3” lift. This bolt-on shock is loaded with position-sensitive technology, vehicle-specific valving, and larger pistons to significantly improve both on-road comfort and off-road performance. The 2.5” impact-extruded aluminum body features a Type II anodized finish for superior heat dissipation and corrosion resistance, while the internal floating piston (IFP) separates shock oil from high-pressure nitrogen to maintain consistent damping.

Hydraulic Top-Out (HTO) technology provides advanced position-sensitive rebound control by forcing oil through a secondary shim stack, reducing harsh top-outs and slowing shaft speed for a smoother, more controlled ride. This makes it especially beneficial for trucks running heavier, more aggressive tires or lifted beyond factory specifications. Designed to increase damping capacity and overall ride comfort, the Fox 2.5 HTO shock delivers a noticeable improvement in performance across all driving conditions.
