Ultra Pro Magnum Roller Rocker Arms - (LS3-L76-L92)
As LS3 engine combinations continue to grow in popularity, Comp Cams has expanded its line of rocker arms to build components specific to LS3 applications. These "Ultra Pro Magnum" rockers are made from investment cast 8650 chromemoly steel, utilize upgraded trunnions and needle bearings. The design is stronger, stiffer and more durable than the stock OEM parts. They also feature a 1.80:1 ratio (compared to the stock 1.70:1 rocker ratio) and utilize a roller tip instead of a slider pad. The higher rocker ratio and increased body 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.
This rocker kit is available as a bolt down design that uses a special stud mount rocker and hardened guide plates for customers looking for a fully adjustable valvetrain. This stud mount design is perfect for individuals running mechanical lifters as well. Comp Cams "Ultra Pro Magnum" rockers arms are available for LS3, L92 and L76 truck engines and come in individual sets or kits featuring studs and guide plates.
This kit does not include hardened push rods, but they are available separately. We recommend purchasing an adjustable push rod and using that to determine the proper length for perfect rocker arm geometry and lifter preload.
