6" 2025-2026 Dodge Ram 2500 4WD (w/diesel engine) Fox 2.5 Performance Elite Coilover Radius Arm Lift Kit by BDS Suspension

BDS Suspension BDS2135PPS / 2135PES 6" Radius Arm Lift Kit upgrades suspension performance, ride quality, and off-road capability on Ram 2500 diesel trucks with a complete extended travel system engineered for strength and drivability. Designed specifically for the diesel platform, this kit provides clearance for up to 37" tires while maintaining proper suspension geometry, corrected driveline angles, and confident on-road handling.

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 steering stability, braking control, and overall ride quality. 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. Additional components, including sway bar links and brake line brackets, maintain proper operating angles throughout the suspension's travel.

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.
