The main body is CNC machined from 6061-T6 aluminum. The mounting location to the hub is integrated into the arm itself to distribute the weight towards the sprung side. This means less unsprung weight and better overall suspension performance. Adjustments are made easily via our signature chromoly adjusters with QA1 rod ends.
USA made QA1 XM series Chromoly Steel heim joints are heat treated for strength and durability. The spherical rod end is completely self-sealing and self-lubricated because of their Nylon/PTFE injection molded race that keeps dirt and debris out.
