HI-TECH PUSHRODS Prior to extensive research at COMP Cams®, it was thought the pushrod only had to be strong enough not to fail, bend, or burn up at the ends. Now COMP Cams engineers have learned that the frequency of the pushrod must match that of all the rest of the parts in the valve train, as well as the RPM at which the engine will be run. Today's all out unlimited race engines deserve the ultimate in quality at every step, and COMP Cams®' High Tech Pushrods fill that requirement. The one piece design from seamless chromemoly tubing insures the ultimate in strength. The ends are precision formed, yielding added thickness in the critical tip area for strength, while maintaining constant wall thickness and concentricity. The pushrods are then heat treated to insure compatibility with guide plates and for maximum strength. They are OD ground for consistency, and black oxide finished with a length and part number laser etched on the OD for ease of identification. These pushrods are all .080''wall thickness.
