What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel, a strong and durable material commonly used in performance engine components. They are also heat-treated and finished with a black oxide coating for added strength and corrosion resistance.

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

A swedged end is formed by compressing the material to create a stronger, more robust connection point. For these push rods, it means the ends are meticulously formed with exact radii, contributing to excellent concentricity and precise length control.

Are these push rods suitable for stock engines?

While these push rods are well-built and feature precise dimensions, they are often chosen for performance engine builds where valve train accuracy is critical. It's always best to consult with your engine builder or refer to specific application guides to ensure they are the right choice for your particular engine setup.

About this part

Product Details

This set includes eight Manley Performance push rods, each measuring 7/16 inches in diameter with a 7.850-inch length and a 0.165-inch wall thickness. They are constructed from 4130 chrome moly steel, known for its strength and durability in high-stress engine applications. The swedged ends are meticulously formed with exact radii, contributing to excellent concentricity and closely controlled length, which are crucial 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 protection against corrosion. The precise manufacturing ensures they fit right and perform reliably in your engine build.
