BDS 6 Inch Long Arm Lift Kit w/ FOX 2.5 Coil-Over Conversion | 2008 Dodge Ram 2500/3500 4WD Diesel | Leaf Spring Rear

Configured with the Leaf Spring rear lift option. Multi-leaf progressive design provides a smooth ride while maintaining factory payload weight ratings. Tapered for correct pinion angle with an offset pin to restore axle position, reducing axle wrap for a more controlled and stable feel.

Overview

This 6-inch lift kit with long arm and FOX 2.5 coil-over conversion from BDS Suspension is designed for 2008 Dodge RAM 2500 and 3500 4WD diesel trucks. The kit improves stance, performance, and capability while providing clearance for up to 37-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 plus mounting brackets, a forged drop pitman arm, track bar bracket, bump stops, and sway bar links. The rear utilizes heavy-duty cast steel blocks or leaf springs, longer u-bolts, and FOX 2.0 Performance shocks.

FOX 2.5 Coil-Overs

FOX 2.5 coil-overs deliver next-level performance for both on-road comfort and off-road capability. Tuned and ready to install out of the box, these 2.5-inch diameter coil-overs include a remote reservoir for additional fluid capacity to keep shocks running cool under demanding conditions.

Long Arm Conversion

The long arm upgrade consists of massive 1/4-inch steel frame-mounted brackets along with oversized upper and lower formed long arms. The arms are formed for maximum tire clearance and allow the stock control arm tabs to remain on the vehicle. The heavy wall tubular lower arms utilize oversized greaseable polyurethane bushings for superior road vibration isolation, while the upper arms are solid stock. The long lower control arms reduce caster change through wheel travel for a more controlled steering feel, and the system retains the factory triangulation of the arms for added suspension stability.
