The COMP Cams Ultra Pro Magnum Roller Rocker Arms ensure optimized lift and valvetrain control at high rpm. They feature an 8650 chrome moly steel construction which is considerably more robust than aluminium and an arched, web-like design which elevates strength and resilience while minimizing the moment of inertia and optimizing the dynamic balance. They are designed with an increased retainer and valve spring clearance which allows the utilization of large-diameter valve springs, retainers, and locks, without any issues in clearance or fitment. They feature an oversized trunnion and precision-sorted needle bearings for the proper integration with high-load valve springs.

These rockers are also fabricated with hardened roller tips which considerably decrease friction and eliminate valve stem "side loading" which often cause premature valve guide wear. These rocker arms have undergone FEA stress analysis and dyno testing to certify a quality that exceeds the standards of the previous models. Furthermore, these rocker arms may be implemented to most Chevy and Ford models and it can be utilized for both street and race engine applications.
