FOX 2.5 Coilover Conversion Upgrade - 4 Inch Lift | Ram 2500 (14-27) & Ram 3500 (13-27) | Diesel - FOX 2.0 Hydro Bump Stop

Transform the ride and capability of your Ram 2500 or 3500 with the FOX 2.5 Performance Elite Coil over Conversion Kit. Designed for heavy-duty trucks that demand comfort, control, and confidence, this system delivers a massive improvement in ride quality both on and off the pavement.

Note: This coil over conversion kit is designed to be used in conjunction with a BDS or Zone Offroad lift kit. A compatible lift system is required for proper installation and performance.

Superior Ride Quality

At the heart of this kit are FOX 2.5-inch diameter Performance Elite coil overs featuring aluminum shock bodies for superior heat dissipation and fade resistance. Compared to the factory suspension, these coil overs dramatically reduce harshness, improve small-bump compliance, and maintain stability under load. Whether you’re daily driving, towing, or tackling rough terrain, the ride is smoother, more controlled, and far more predictable.

Unmatched Tunability with DSC Adjusters

Equipped with FOX’s Dual Speed Compression (DSC) adjusters, these coil overs allow you to fine-tune your suspension to match your driving style and conditions. Independently adjust low-speed and high-speed compression to dial in comfort for highway cruising, added support for towing, or firmer control for aggressive off-road use—all without removing the shocks. One suspension system, fully adaptable to how you use your truck.

Performance That Looks as Good as It Feels

The FOX Performance Elite series isn’t just built to perform, it looks the part too. Signature clear-anodized aluminum bodies, black anodized components, and race-inspired hardware give your Ram a premium, high-performance appearance that stands out behind the wheels.

Optional FOX 2.0 Hydraulic Bump Stops

For drivers who push their trucks harder off-road, optional FOX 2.0 Hydraulic Bump Stops provide added bottom-out control and protection. These bumps absorb hard impacts, reduce chassis shock, and further enhance ride quality in aggressive terrain.
