COMP Cams Ultra Pro Magnum Roller Rockers - Bolt Down - GM LS1/LS2/LS6/Cathedral Port Heads 1677-16

New LS-Specific Ultra Pro Magnum™ Rocker Arms From COMP Cams® Increase Ratio And Stiffness Over Stock Rockers, While Also Increasing Lift Without The Need To Swap Cams

As LS engines continue to grow in popularity, COMP Cams® has expanded its line of rocker arms to build components specific to LS applications. New Ultra Pro Magnum™ Rockers are made from investment-cast 8650 chromemoly steel, utilize upgraded trunnions and needle bearings over stock and are stronger, stiffer and more durable than the stock parts. They also feature a 1.8 ratio (compared to the stock rockers’ 1.7) and utilize a roller tip instead of a slider. The higher ratio and increased stiffness make these rockers a great option for increasing lift without changing cams. This increased stiffness, along with the upgraded trunnion package and roller wheel, also makes them a perfect choice when running aftermarket valve springs. The rockers are available in a bolt-down design that uses stock rocker stands and in a stud-mount option for customers looking for an adjustable valve train. The stud-mount version is perfect for individuals running mechanical lifters as well. COMP Cams® LS Ultra Pro Mangum™ Rockers Arms are available for LS1, LS2, LS3, LS6 and LS-based truck engines and come in individual sets or kits featuring studs and guide plates. Kits do not include pushrods, but they are available separately.
