The latest development in rocker arm technology from COMP Cams® are Ultra Pro Magnum™ Rocker Arms built for 1/2″ studs to increase valve train stiffness and stability.
Designed to be used in conjunction with the COMP Cams® Hi-Tech 1/2″ Rocker Stud Kit, the latest versions of COMP Cams® Ultra Pro Magnum Rockers are built to utilize 1/2″ studs to stabilize BBC valve trains. Ultra Pro Magnum™ Roller Rocker Arms feature a modern arched, web-like design to deliver increased strength and rigidity while still reducing the moment of inertia and optimizing the dynamic balance. The rockers also boast precision-sorted needle bearings and hardened roller tips. And since they now feature the added benefit of accepting 1/2″ studs, they are a great choice for anyone looking for more stiffness with stud mount rockers. These new Ultra Pro Magnum™ Rocker Arms will provide the ultimate in valve train stability for maximum valve motion both at the track and on the street.
Utilizing years of valvetrain design experience, the latest FEA stress analysis technology, and an exhaustive testing regiment (dyno and Spintron), COMP Cams engineering team left no detail to chance. Everything from casting techniques to valve spring clearance was scrutinized to ensure that Ultra Pro Magnum rocker arms not only lived up to the lofty standards of their predecessor, but also took stud mount rocker performance, stability, and value to a whole new level. The most noticeable advancement centers around their nearly unbreakable investment cast 8650 chromoly body. The arched, web-like design delivers a nearly 29 percent increase in strength and rigidity, while reducing the moment of inertia and optimizing the dynamic balance.
