One way to increase power is to increase lift. That’s what makes the Competition Cams Magnum steel roller-tip rocker arms so popular. They’re one of the highest-lift rockers you can get outside of racing. And, along with the lift, you also get grooved pivot balls and roller tips to prevent valve stem and guide wear. Note: Steel offset rocker arms available on special order. CCA-1431 cannot be used on engines with short valve tips; use CCA-1412 or CCA-1416. *For 1987-97 engines with centerbolt valve covers.
