4" 2025-2026 Dodge Ram 2500 4WD Fox 2.5 Performance Elite Coilover Radius Arm Lift Kit by BDS Suspension

BDS 4" Radius Arm Lift Kit for Ram 2500 diesel trucks improves suspension geometry, ride quality, and off-road capability while maintaining excellent on-road comfort and drivability. Designed specifically for diesel applications, this system allows for up to 37" tire fitment while correcting driveline angles and increasing suspension travel for confident performance in any environment.

At the core of this system are heavy-duty tubular radius arms that properly position the front axle and restore caster geometry lost when lifting, improving straight-line stability, steering return-to-center, and braking control. A transfer case indexing ring is included to optimize driveline angles and increase suspension droop, while a track bar relocation bracket ensures proper axle centering and steering alignment.

FOX 2.5 Performance Elite front coilovers enhance damping control and ride quality, and can be paired with either rubber bump stops for predictable engagement or FOX 2.0 hydraulic bump stops for high-speed impact absorption and aggressive off-road performance. Coilover systems paired with FOX 2.0 hydraulic bump stops are configured exclusively with FOX 2.5 Performance Elite shocks for maximum capability and control.

Shock options allow further customization of ride quality and performance. FOX 2.5 Performance Series HTO shocks add increased oil capacity and position-sensitive rebound control, while FOX 2.5 Performance Elite shocks with DSC adjusters deliver top-tier performance with independent high- and low-speed compression tuning for maximum versatility on any terrain.
