This Ultra Pro Magnum rocker is made of black oxide coated 8650 chromemoly steel that can withstand up to 850 lbs of spring pressure. Featuring a 1.7 ratio, this rocker fits Chevrolet 348-409 with a 3/8" diameter stud.
As LS engines continue to grow in popularity, COMP Cams(R) has expanded its line of rocker arms to build components specific to LS applications. New Ultra Pro Magnum(TM) Rockers are made from investment-cast 8650 Chromemoly steel, utilize upgraded Trunions 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 Trunion 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(R) LS Ultra Pro Mangum(TM) 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.
