BDS Suspension 2013-18 Ram 3500 Diesel 4wd 6" Suspension System.
This system is for the all new redesigned front suspension for the Ram heavy duty trucks. The lift is designed around the relocation of the factory radius arm in order to correct suspension and steering geometry to work with 6" of lift. The radius arms are relocated with a uniquely designed bracket that mixes the ease of installation you get with an adapter-type bracket with the strength and durability of a full replacement radius arm mount bracket. The new relocation bracket ties into both the factory radius arm frame mount and the side of the frame rail.
At the frame, the new mount is fastened with specially machined sleeves and threaded inserts. The threaded inserts (2) do require a minor amount of welding in order to provide the strongest possible connection. This portion of the installation can be completed without welding and then transported to a weld shop to be welded if necessary.
In addition to the radius arm relocation, the kit includes everything else to properly lift the 2013-18 Ram 3500's. Track bar relocation, dropped pitman arm and brake line relocation hardware position all the steering and brake components properly to work with the added ride height provided by the new progressive rate, full replacement coils springs.
In the front, sway bar relocation brackets drop the sway bar at the frame to correct the sway bar angle and allow use of the factory sway bar links. New 6" progressive rate coil springs provide the correct ride height and great on/off road ride quality.
The front driveshaft on the new Ram trucks has a more limited range of motion compared to the previous generation trucks. In order to correct the driveline angles, we include a new transmission crossmember with an adjustable height transmission mount plate and a transfer case indexing ring kit. Unlike the previous generation trucks, there is not enough clearance between the transfer case and the factory transmission crossmember to install an indexing ring on its own. The new crossmember provides the clearance needed. The ability to adjust the transmission mount height is an added bonus and nice "fine-tuning" feature.
The rear of the truck is lifted via a 5" block and u-bolt system which provides a level-to-slightly tail high stance.
