This ultimate kit boasts a set of ultra-durable Forged Aluminum Upper Control Arms with a reinforced gusset plate and Clevite rubber bushings.

This all-inclusive kit comes with everything you need, and installation is a piece of cake compared to other kits on the market! Featuring a 100% bolt-on installation process that requires zero cutting or drilling, this kit can be installed using common tools in a home garage, and allows the truck to be returned to stock at any time if so desired.
