What material are these push rods made from?

These Manley push rods are constructed from 4130 chrome moly tubing. This material is known for its strength and durability, making it a popular choice for performance engine components.

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

A swedged end means the tube has been compressed and shaped at the ends. For these push rods, it ensures the ends are precisely formed with exact radii, which helps them seat properly in the lifters and rocker arms for consistent valve train operation.

What is the purpose of the black oxide finish?

The black oxide finish is applied after heat treatment. It helps to provide added durability to the push rods and offers some resistance against corrosion, keeping them in good condition.

About this part

Product Details

These Manley push rods are made from 4130 chrome moly tubing with a 0.080 inch wall thickness, giving them a solid foundation for your engine build. The swedged ends are meticulously formed with exact radii, ensuring they seat properly in your lifters and rocker arms. This attention to detail helps maintain excellent concentricity and closely controlled lengths across the set of 16, which is crucial for consistent valve train geometry. They are heat-treated and finished with a black oxide coating for added durability and corrosion resistance.

When you're rebuilding the top end of your engine, the push rods are a key component that transfers the camshaft's motion to the valvetrain. Using well-made push rods like these from Manley can help ensure smooth operation and reliable performance. The 4130 chrome moly construction offers a good balance of strength and weight, while the precise manufacturing helps prevent valvetrain noise and wear.
