The radius arm approach mounts in the factory location with caster adjustment and OE-style rubber bushings, keeping refinement while correcting geometry. The T-case indexing ring and crossmember are included — BDS has addressed the driveline angle requirements at this lift height. The tool requirement is the lightest of any BDS kit in this catalog: a pitman arm puller is the only specialty tool listed.
