Description:

The FOX 2.5 Performance Series Hydraulic Top-Out (HTO) Rear Shock is engineered to improve ride quality, suspension control, and damping performance on 2014–2026 Ram 3500 trucks. Featuring a large 2.5” aluminum shock body, vehicle-specific valving, and an internal floating piston, this shock delivers increased damping capacity and consistent performance for both daily driving and demanding applications.

FOX Hydraulic Top-Out technology provides 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, reducing abrupt suspension impacts and improving overall ride comfort. This technology is particularly beneficial for heavy-duty trucks equipped with larger tires or operating in conditions where additional suspension control is needed.

Built with a corrosion-resistant Type II anodized aluminum body, the FOX 2.5 Performance Series HTO Rear Shock combines durable construction with advanced damping technology. Compatible with both single and dual rear wheel configurations, including factory air suspension-equipped trucks, this shock is a direct-fit upgrade for Ram 3500 owners looking for improved ride quality and suspension performance.
