About this part

Product Details

What you get with this order is a single, well-built pushrod measuring 9.050 inches long. It features a 7/16 inch diameter and a .165 inch wall thickness, which is notably thicker and stiffer than common .080 or .125 inch wall designs. This pushrod is made in the USA from one-piece, heat-treated chromemoly tubing, a material that's stronger than typical 1000 Series steels and is built to handle demanding valve train setups.

The design incorporates technology originally developed for NASCAR and NHRA race engines, where pushrods can experience impact loads up to 7500 lbs. The 7/16 inch diameter offers increased stiffness and a higher natural frequency, which is a significant advantage when you have ample intake port and lifter clearance. Both ends of the pushrod feature a 5/16 inch ball end with a 210-degree radius. This radius provides extra clearance for the rocker adjuster at high lift and allows the pushrod to be installed in either orientation.
