The COMP Cams Ultra Pro Magnum Roller Rocker Arm is a next-generation premium rocker arm that is thoroughly engineered to outperform and outlast the competition. COMP Cams' designers have utilized computer-aided design to restructure an already great rocker arm with an advanced blueprint that increases strength and reduces overall mass. Featuring a fully-rebuildable design, the Ultra Pro Magnum Roller Rocker Arm improves the lift and valve train control at high rpm operation. Built from 8650 chrome moly steel which is 300% stronger than extruded 7075-T6 aluminum, this rocker arm can cycle for a lifetime with very little chances of failure. By utilizing this build, COMP Cams' engineers are able to reduce the deflection from the fulcrum point to the roller tip which results in a lighter rocker arm. When this COMP Cams Rocker Arm was subjected to FEA stress analysis and dyno testing, the result showed that it was 29% stiffer than the originals. It also reduces the mass moment of inertia while improving dynamic balance. The roller tips have proven to reduce friction and eliminate premature valve guide wear. As a testament to its durability, COMP Cams offers a lifetime warranty against breakage of the rocker arm body. The Ultra Pro Magnum Roller Rocker Arm can be fitted to most Chevy and Ford models and it can be used for both street and race engine applications.
