What material are these pushrods made from?

These pushrods are made in the USA from one-piece, heat-treated 4130 chromemoly steel tubing. This material is known for its strength and durability.

What is the benefit of the dual taper design?

The dual taper design means the middle of the pushrod is larger in diameter than the ends. This offers the clearance benefits of a 3/8" pushrod while maintaining the rigidity of a 7/16" pushrod, especially around rocker arms and offset lifters.

How does the .165" wall thickness help?

The thicker .165" wall makes the pushrod stiffer and stronger than previous .125" wall offerings. This improved stiffness leads to more accurate valve motion and better overall durability for your engine's valve train.

Product Details

Starting with a .165-inch wall thickness, this COMP Cams pushrod offers a stiffer and stronger option compared to previous .125-inch wall designs. This improved rigidity translates directly into more accurate valve motion, which is crucial for consistent engine performance. The pushrod itself is 8.650 inches long and features a dual taper design, meaning the middle section is larger in diameter than the ends. This unique shape provides the benefits of a larger 7/16-inch pushrod while still offering the clearance typically found with a 3/8-inch pushrod, especially around rocker arm adjusters at peak lift and most offset roller lifters.

Crafted in the USA from a single piece of heat-treated 4130 chromemoly steel tubing, these pushrods are built to be stronger than many others available. The 5/16-inch ball ends are formed with a 210-degree radius, further enhancing clearance and ensuring proper seating. If you're rebuilding an engine and need reliable components for precise valve train operation, this pushrod is a solid option.
