      Part No. 1411-16

      Warranty Details (90 DAY REPLACEMENT IF DEFECTIVE)

      These Magnum Roller Rocker Arms for Chevy V8 396-454; Ford Boss 302, 351C-400M; and Ford V8 429-460 applications are the ultimate street rocker. With a 7/16" stud diameter and 1.72 ratio, 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.
