Description

Comp Cams LS3 Stud Mount Roller Rockers, adjustable for 3/8 studs

Comp Cams Ultra Pro Magnum rockers are made of black oxide coated 8650 chromemoly steel that can withstand up to 850 lbs of spring pressure. Featuring a 1.8 ratio, these rockers fit LS3 with a 3/8" diameter stud.

COMP Cams has expanded its line of rocker arms to build components specific to LS3 applications. New Ultra Pro Magnum LS3 Rockers are made from investment-cast 8650 chromemoly steel, with upgraded trunnions & 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 LS3 Ultra Pro Mangum Rockers Arms.
