The stock upper control arm bushings found on most cars have serrations inside the bushings to keep the arms from rotating freely. These serrations cause the bushings to twist and create friction that suppresses front end lift and hinders weight transfer. By installing Competition Engineering Upper A-Arm Bushings, you eliminate the serrations. This allows the A-arm to pivot freely on the cross shaft resulting in rapid front end lift and increased weight transfer. More positive steering, eliminates flex during launch and braking for better control. Billet 6061-T6 aluminum is far superior to O.E. style split sleeves.
