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.

Why is the dual taper design important?

The dual taper design means the middle of the pushrod is larger than the ends. This provides the rigidity of a larger diameter pushrod while still offering the clearance of a smaller one, which is beneficial for rocker arm adjuster clearance at peak lift.

What is the wall thickness and why does it matter?

These pushrods have a .165-inch wall thickness, which is stiffer and stronger than previous .125-inch wall offerings. A stiffer pushrod leads to more accurate valve motion and better overall durability for your engine's valve train.

Product Details

When you're rebuilding the top end of your engine, getting the valve train geometry just right is critical for performance and durability. These Dual Taper pushrods from COMP Cams are designed to help you achieve that precision. They measure 8.650 inches long and feature a unique dual taper design where the middle section is larger in diameter than the ends. This gives you the benefits of a beefier 7/16-inch pushrod for stiffness, while still offering the clearance of a 3/8-inch pushrod, which is especially helpful for clearing rocker arm adjusters at peak lift and accommodating higher-flowing intake ports.

Built for accuracy and longevity, these pushrods are constructed from a single piece of heat-treated 4130 chromemoly steel tubing right here in the USA. The .165-inch wall thickness is notably stiffer and stronger than previous .125-inch wall offerings, leading to more accurate valve motion and improved durability over time. The 5/16-inch ball ends are also shaped with a 210-degree radius to provide additional clearance where it's needed most, particularly with offset roller lifters.
