What makes this pushrod stronger than standard ones?

This pushrod is made from one-piece, heat-treated chromemoly tubing, which is stronger than typical 1000 Series steels. It also features a thicker .165 inch wall, providing more stiffness and durability for extreme valve train setups.

What is the advantage of the 7/16 inch diameter?

The larger 7/16 inch diameter offers increased stiffness and a higher natural frequency. This is beneficial in applications with ample intake port and lifter clearance, helping to prevent flex under high loads.

Can these pushrods be installed in either direction?

Yes, the radiused ball ends on both sides allow for installation in either orientation. This feature also provides additional clearance for the rocker adjuster at high lift.

Product Details

If you're working on a high-performance engine build, especially one that sees serious track time, a strong pushrod is crucial. This COMP Cams pushrod is built for those demanding applications. It's 9.600 inches long, with a 7/16 inch diameter, offering a significant stiffness advantage over common, thinner wall pushrods. This helps prevent flex under extreme valve spring pressures and high lift camshafts, which is vital for maintaining consistent valve timing and preventing catastrophic engine failure.

COMP Cams developed the technology behind these pushrods from their experience in NASCAR and NHRA racing, where pushrods can see impact loads up to 7500 lbs. They're made in the USA from one-piece, heat-treated chromemoly tubing, which is notably stronger than standard 1000 Series steels. The .165 inch wall thickness is consistent throughout, even in the tapered ends, providing a solid foundation for your valve train. The 5/16 inch ball ends are radiused, giving extra clearance for rocker adjuster movement at high lift and allowing for installation in either orientation.
