 GM Gen III LS1/LS6 Ultra Pro Rocker Arms Rocker Stud: 3/8 Ratio: 1.80

COMP Cams® Ultra Pro Magnum™ Roller Rocker Arms Built entirely from 8650 chromemoly steel, fully rebuildable Pro Magnum™ Rockers are so tough that they have a lifetime warranty on the rocker bodies. A massive trunion allows more needle bearings to be used for greatly increased load capacity while still providing plenty of clearance for most high performance valve springs. Ideally suited for serious street, bracket racing, super classes, and circle track racing.
