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.
