What material are these push rods made from?

These push rods are constructed from 4130 Chrome Moly steel. This is a strong and durable material commonly used in performance engine components.

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

A swedged end means the end of the tube has been compressed and shaped, creating a stronger and more precise connection point where it interfaces with the lifter and rocker arm.

Are these push rods suitable for a stock engine rebuild?

While these are well-built push rods, their specifications and material suggest they are often used in performance or modified engine builds where precise valvetrain geometry and durability are important. Always confirm compatibility with your specific engine build.

About this part

Product Details

If you're rebuilding the top end of your engine, getting the valvetrain geometry just right is key. These push rods from Manley Performance are designed to help you achieve that precision. They're made from 4130 Chrome Moly steel, a strong material that holds up well under the stresses of engine operation.

Manley paid close attention to the details with these push rods. The ends are meticulously formed with exact radii, and they maintain excellent concentricity and closely controlled length. This means they'll seat properly and operate smoothly within your valvetrain. They're also heat-treated and finished with a black oxide coating for added durability and corrosion resistance.

This set includes eight push rods, each measuring 7/16 inch in diameter with a 0.165 inch wall thickness and a length of 11.500 inches. The swedged ends are a common feature that helps ensure a solid connection within the rocker arms and lifters.
