What material are these push rods made from?

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

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

A swedged end means the end of the tube has been compressed and formed to create a stronger, thicker section. This design helps prevent the end from mushrooming or deforming under the stress of valvetrain operation.

Are these push rods suitable for all engine builds?

These push rods are designed for specific engine applications where their dimensions and material properties are a good match. It's important to verify that the 3/8 inch diameter, 7.475 inch length, and 0.080 inch wall thickness are correct for your particular engine build.

About this part

Product Details

This set includes eight Manley Performance push rods, each measuring 3/8 inch in diameter with a 7.475 inch length and a 0.080 inch wall thickness. They are constructed from 4130 chrome moly steel and feature swedged ends for improved strength and durability. These push rods are a key component in your engine's valvetrain, transferring the motion from the lifters to the rocker arms.

Manley has paid close attention to the details with these push rods. The ends are meticulously formed with exact radii, ensuring proper contact with the lifters and rocker arms. They also exhibit excellent concentricity, meaning they are perfectly round and balanced, which helps maintain consistent valvetrain geometry. The closely controlled length is critical for achieving the correct valve lash settings during engine assembly. Heat treatment and a black oxide finish add to their resilience and help protect against corrosion.

When rebuilding or modifying an engine, selecting reliable valvetrain components is important. These push rods are a solid option for many applications where precise valvetrain operation is needed.
