COMP Cams Shaft Mount Aluminum Rocker Arms

COMP Cams shaft mount aluminum rocker arms are one of the most cost-effective ways to increase horsepower. These shaft rockers were designed using the latest in computer software and engineering. They center the roller tip over the valve tip at the correct time so that the roller tip is never more than 0.020 in. off-center of the valve tip. At the greatest load point, the roller tip contact is on the center of the valve. At valve closing, the roller tip contact is slightly behind the valve centerline. When the valve is at full open, the tip contact is slightly behind the centerline of the valve. The results are more horsepower and better performance.
