2013-2018 Cummins 4" Lift kit w/o Air Ride (BDS696H)

Take your Cummins up a notch with this BDS 4" Suspension System. This system is for the all-new redesigned front suspension for the Ram HD trucks. Designed around the relocation of the factory radius arm in order to correct suspension and steering geometry to work with 4" 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.

  • 37" x 12.50 w/ 17" x 9" and 5.625"
  • 35" x 12.50" w/ 18" x 9" and 4.5
  • 35" x 12.50" w/ 20" x 9" and 4.5

  • The carrier bearing drop kit (122405) is necessary for models equipped with a two-piece rear driveshaft.
