(16) Ultra Pro Magnum" Roller Rockers - Stud Mount - GM LS3/L99/L76/Rectangle Port Heads
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.
