Comp Cams LS1 LS6 1.85 Rocker Arm Kit Comp Cams LS1 LS6 1.85 Rocker Arm Kit COMP Â GM Gen III/LS1/LS6 Pro-Magnum Rocker Arm Kit with 5/16" Flat guide plates. Kit Includes:Â Pro-Magnum Rocker arms (#1370-16), 5/16 Flat Guide plates for 5/16 pushrods (#4854-8), 3/8 Rocker Studs (#4554-16), 3/8 adjusting nut (#4654-16), and Set screw for 4654 (#465SS-16) Pro Magnum Roller Rocker Armsâ„¢Before we introduced our revolutionary Pro Magnum Rocker Armsâ„¢ there were only two alternatives in competition rocker arms: Stainless Steel for strength and reliability or Aluminum for light weight and low cost. With the Pro Magnum Rockersâ„¢ you get the best of both worlds. Pro Magnum Rockersâ„¢ are made of 8650 chromemoly steel. This material is some three times stronger than 7075-T6 aluminum which is used for most aluminum rocker arms. Our engineers used advanced computer technology (including Finite Element Analysis) to refine the Pro Magnum Rockerâ„¢. We added strength where it was needed and reduced mass in low stress areas. The result: Pro Magnum Rocker Armsâ„¢ have less weight (5%) at the valve than most aluminum rockers. This means more RPM and valve train stability. The unique design of the Pro Magnum Rockerâ„¢ enables us to use a larger trunion with more needle bearings. This spreads the load more evenly and the rocker will last longer. Other features include an integral pushrod seat that insures accuracy and saves weight, a unique rocker design also provides plenty of clearance for most high performance valve springs.
