Overview

This 8-inch lift kit with long arm and FOX 2.5 coil-over conversion from BDS Suspension is designed for 2009–2013 Dodge RAM 2500 4WD diesel trucks. The kit improves stance, performance, and capability while providing clearance for up to 38-inch tires. BDS developed a mounting system that bolts directly to the factory coil mounts with only minor trimming and drilling required, along with weld-in reinforcements at the axle for superior strength.

Up front, the kit includes FOX 2.5 coil-over shocks, all four control arms with mounting brackets, a forged drop pitman arm, track bar bracket for steering correction, bump stops, and sway bar links. The rear utilizes heavy-duty cast steel blocks, longer U-bolts, and a matching set of FOX 2.0 Performance shocks.
