What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel, a material known for its strength and durability. They also feature a heat treatment and black oxide finish for added wear resistance.

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

A swedged end is a manufacturing process where the end of the tube is compressed and shaped. For these push rods, it creates a strong, integrated connection point that contributes to the overall stability of the valvetrain.

Are these push rods suitable for a stock engine rebuild?

While these push rods are well-built and feature precise dimensions, they are often chosen for performance applications due to their robust construction. For a stock rebuild, it's always best to consult your engine's service manual or a qualified mechanic to ensure they meet your specific needs.

About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and these push rods are a great example of that. If you're rebuilding or upgrading your engine's valvetrain, these push rods are built to handle the demands of performance use. They are made from 4130 chrome moly, a material chosen for its good strength-to-weight ratio, and feature a 0.165-inch wall thickness for added rigidity.

What really sets these apart is the attention to detail in their construction. The ends are meticulously formed with exact radii, and Manley controls the length very closely, ensuring excellent concentricity. This precision helps maintain consistent valve train geometry, which is crucial for reliable operation, especially when you're pushing your engine harder. They also come heat-treated and finished with a black oxide coating for durability.

This set includes eight push rods, enough for a typical V8 engine. The swedged ends are designed to provide a solid connection point, contributing to the overall stability of your valvetrain.
