What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel. This material is known for its strength and durability, making it a popular choice for performance engine applications.

What does the black oxide finish do?

The black oxide finish provides a layer of corrosion resistance to help protect the push rods from rust and environmental damage. It also contributes to the overall durability of the component.

Are these push rods suitable for stock engines?

While these push rods are well-built and offer improved durability, they are often chosen for performance builds where increased valvetrain stress is expected. Always consult with your engine builder or a qualified mechanic to ensure they are the right choice for your specific application.

About this part

Product Details

This set includes 16 Manley push rods, each measuring 5/16 inches in diameter with a 0.120-inch wall thickness and a length of 6.650 inches. They are constructed from 4130 chrome moly steel, a strong material often used in performance engine builds for its durability and resistance to bending under stress. The swedged ends are meticulously formed with exact radii, and the set boasts excellent concentricity and closely controlled lengths, ensuring they fit and function precisely within your engine.

These push rods are heat-treated and finished with a black oxide coating. This treatment process helps to increase their strength and wear resistance, while the black oxide finish offers a layer of corrosion protection. The precise manufacturing, including the swedged ends and controlled lengths, is important for maintaining proper valve train geometry and ensuring consistent performance, especially in engines that see higher RPMs or increased valvetrain stress.
