Comp Cams 8761-1 - Comp Cams Hi-Tech 3/8

Hi-Tech Pushrods with 3/8'' diameter and a .065'' wall thickness are made of high-quality 4130 chromemoly steel heat-treated to a minimum hardness of 60 on the Rockwell ''C'' scale. the use of finite element analysis has helped Comp Cams to design this pushrod for superior performance and endurance. Applications include engines employing mid-range spring pressures and high engine speeds. Because of their increase in natural frequency, these pushrods help tune the valve train when subjecting the valve train to its maximum speed. Spintron tests show that this product helps control valve motion, which results in capturing lost horsepower due to valve bounce. They are OD ground for consistency and black-oxide finished with length and part number laser etched on for easy identification.
