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 longevity.

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 fit where it connects to the lifter or rocker arm. This design helps ensure consistent valve train geometry.

Are these push rods suitable for all engine builds?

These push rods are a well-built option for many engine builds, particularly those requiring precise valve train geometry and durable components. It's always best to consult your engine's specific service manual or a qualified mechanic to ensure they are the correct specification for your particular application.

About this part

Product Details

This set includes eight Manley Performance push rods, each measuring 7/16 inches in diameter with an 8.300-inch length and a 0.165-inch wall thickness. They are constructed from 4130 chrome moly steel and feature swedged ends for a secure connection. These push rods are essential for transferring the motion from your lifters to your rocker arms, playing a key role in the valve train's operation.

Manley builds these push rods with meticulous attention to detail, ensuring excellent concentricity and closely controlled lengths for consistent operation. The ends are carefully formed with exact radii, which helps them seat properly against the lifters and rocker arms. They are also heat-treated and finished with a black oxide coating, which adds a layer of durability and helps prevent corrosion.

When rebuilding or modifying an engine, especially one where precise valve train geometry is critical, these push rods offer a well-built option. Their solid construction from 4130 chrome moly means they can handle the demands of higher performance applications. Always refer to your engine's service manual for specific installation procedures and recommended components.
