The latest development in rocker arm technology from COMP Cams® are Ultra Pro Magnum™ XD 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 XD are built to utilize 1/2" studs to stabilize SBC valve trains.
