The CST Performance Suspension Dirt Series Upper Control Arm # CSS-C4-6 is an all new and improved design. This Generation II features a sealed UniBall top cap design which helps improve Uni-Ball life by reducing the amount of contaminants that enter the Uni-Ball itself. Because the CST sealed UniBall cup has a steel dome design they can run the shock mounting gussets right over the top of the arm. This helps increase strength and gets the shock mounts in a more desireable location. Added strength, better looks, longer component life and made right here in the USA!
