CO1622-16 - COMP CAMS ULTRA PRO SHAFT MNT ROLLER ROCKERS FITS SB CHRYSLER 1.5 PK

COMP Cams Rocker Arm, Ultra Pro Magnum, Full Roller, Chromoly Steel, 1.5 Ratio, Shaft Mount for Chrysler 273-360, 16-SET

COMP Cams Pro Magnum shaft mount roller rocker arms combine the strength of 8650 chromoly steel and the weight savings of aluminium rockers. COMP Cams took advantage of computer design to simulate the stresses that affect rockers under various operating loads. This allowed the engineers to lessen the rockers' mass at non-critical areas and strengthen the areas that take the most punishment. The results are rocker arms that are strong where they need to be and actually weigh 5 percent less at the valve than comparable aluminium rockers.
