Notes: Rocker Arm Magnum Roller Steel Nitrided 1.6 Ratio Rocker Arm Chevrolet V6/Small Block w 3/8 in. Stud
These Magnum Roller Rocker Arms are the ultimate street rocker. 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. Image is a representation. Actual product may vary
