Raise your RAM 3500 gas powered truck to the next heights with this 4-inch lift kit with 4-Link conversion from BDS Suspension. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 35" tires.

Up front the lift kit includes gas-specific Pro-Ride coil springs, 4-Link control arms and conversion brackets, forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, brake line brackets and precision tuned NX2 or FOX 2.0 nitrogen charged shocks.


At this height, the transfer case needs to be indexed to allow use of the factory front driveshaft so an indexing ring and new transmission crossmember are supplied. In the rear this kit utilizes a high-strength steel lift block, longer u-bolts and a matching set of NX2 Nitro or FOX 2.0 Performance shocks.

Rear Lift Option
