The new BDS Suspension 5.5" suspension system is design with our tried-and-true steering knuckle and crossmember technology. The system has passed FMVSS126 testing for stability control compliance. Heavy-duty fabricated crossmembers drop the lower control arms, perfectly matching the massive ductile cast iron extended steering knuckles to gain 5.5" of lift.
The crossmembers utilize the factory alignment eccentrics and tie together with a full-width skid plate. The skid plate protects the relocated differential that has been lowered and positioned to work precisely with the included transfer case indexing ring, allowing for the factory front drive shaft to be used.
The factory front struts are relocated using upper strut extensions that do not require disassembly of the strut. Front bump stop extension and sway bar links are included as well as new Moog tie rod ends to properly set alignment without trimming the inner tie rods.
In the rear, as simple block/u-bolt combination sets the new ride height so it is level with the front. Fox 2.0 or NX² series rear shocks are available to finish out the back.
