This kit includes tools to make rebuilding both the small and large BDS control arm flex ends easier both on the trail and in the shop. The kit consists of specifically designed compression tools that fit inside the outer washers of the flex ends to apply proper pressure to the assembly allowing snap ring removal and installation. The tools use a bolt and nut setup that can be installed with simple hand wrenches. In the shop, the bolt can be mounted in a bench vise to make the process even easier.
