These Ultra Pro Magnum rockers are made of black oxide coated 8650 chromemoly steel that can withstand up to 850 lbs of spring pressure. Featuring a 1.52 ratio, these rockers fit '88+ Chevrolet Small Blocks with a 3/8" diameter stud.
Utilizing years of Valvetrain design experience, the latest FEA stress analysis technology, and an exhaustive testing regiment (Dyno and Spintron), the COMP Cams engineering team left no detail to chance. Everything from casting techniques to valve spring clearance was scrutinized to ensure that the new Ultra Pro Magnum rocker arms not only lived up to the lofty standards of their predecessor, but also took stud mount rocker performance, stability, and value to a whole new level.
