2013-2018 Cummins 6" BDS Lift Kit (BDS699H)
This system is for the all-new redesigned front suspension for the Ram heavy-duty trucks lifting it 6" over the factory height. The lift is designed around the relocation of the factory radius arm in order to correct suspension and steering geometry to work with the 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.
