What material are these push rods made from?

These push rods are made from 4130 chrome moly steel. This material is chosen for its strength and durability in demanding engine environments.

What does 'swedged end' mean for these push rods?

A swedged end means the end of the tube has been formed and reinforced, typically to accept a ball or cup end. For these push rods, it contributes to improved strength and concentricity at the ends.

What is the purpose of the black oxide finish?

The black oxide finish serves as a protective coating. It helps to resist corrosion and provides a measure of wear resistance for the push rods.

About this part

Product Details

This is a set of eight Manley Performance push rods, measuring 7/16 inch in diameter with a length of 11.250 inches and a wall thickness of 0.165 inches. They are constructed from 4130 chrome moly steel, a well-known material for its strength and durability in high-performance engine applications. The swedged ends are meticulously formed with exact radii, contributing to excellent concentricity and closely controlled length, which are critical for proper valve train operation.

These push rods are heat-treated and finished with a black oxide coating. This treatment process helps to increase their strength and resistance to wear, while the black oxide finish offers a layer of corrosion protection. The precise manufacturing ensures that each push rod in the set maintains excellent concentricity and length accuracy, vital for consistent performance and preventing premature wear in your engine's valve train.
