Important Fitment Details:
- Designed for trucks equipped with 2–3” of front suspension lift.
- Not compatible with stock-height applications due to extended shock length.
- Sold individually.
Features:
-
FOX Hydraulic Top-Out (HTO) Technology – Position-sensitive rebound damping reduces harsh suspension top-out events for a smoother, more controlled ride.
-
2.5” Aluminum Shock Body – Impact-extruded 6061-T6 aluminum construction provides increased damping capacity and efficient heat dissipation.
-
Vehicle-Specific Valving – High-flow, velocity-sensitive damping is engineered to improve ride comfort and suspension control both on and off the road.
-
Internal Floating Piston (IFP) – Separates shock oil from high-pressure nitrogen to help prevent aeration and maintain consistent damping performance.

Description:
The FOX 2.5 Performance Series Hydraulic Top-Out (HTO) Front Shock is engineered to deliver improved ride quality, suspension control, and damping performance for lifted Ram 2500 and 3500 trucks. Featuring a 2.5” impact-extruded aluminum body, vehicle-specific valving, and an internal floating piston, this shock provides increased damping capacity and consistent performance for both daily driving and demanding off-road conditions.
FOX Hydraulic Top-Out technology introduces position-sensitive rebound damping to reduce harsh top-out events as the suspension approaches full extension. By directing shock oil through a secondary shim stack, the HTO system slows shaft movement near the end of rebound travel, helping eliminate the abrupt impact commonly experienced with conventional shocks. This technology is particularly beneficial for leveled trucks and applications equipped with larger, heavier tires.
Built with a corrosion-resistant Type II anodized aluminum body and a 5/8” hard chrome shaft, the FOX 2.5 Performance Series HTO Shock combines durable construction with advanced damping technology. Designed for Ram trucks equipped with 2–3” of front lift, it delivers a more refined, controlled ride without sacrificing suspension performance.
