Product Description

They are designed for serious performance enthusiasts. All magnum roller rocker arms are constructed from 8620 chromemoly steel, which is a superior material that will not flex and assures maximum lift. Their roller tip reduces friction, while stiff design and superior ratio accuracy yield more effective valve lift. With a 15 to 30 horsepower increase over other rocker arms, magnum roller rockers are perfect for performance applications with less than 350 lbs. Open spring pressure. Don't accept inferior products or cheap knock-offs, look for the COMP Cams logo stamped into the underside of every magnum rocker.
