What material are these push rods made from?

These push rods are made from 4130 chrome moly steel, a strong and lightweight alloy commonly used in performance engine components. They are also heat-treated and finished with a black oxide coating for added durability.

What is the purpose of the swedged end?

The swedged end is a design feature that reinforces the push rod at its contact points, adding strength and durability where it's most needed during engine operation.

Are these push rods suitable for all engines?

These push rods have a specific length of 10.350 inches and a diameter of 7/16 inches. While they are built for performance, it's crucial to verify that this exact length and diameter are correct for your engine's specific valvetrain geometry and components.

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 builds. They measure 7/16 inches in diameter with a 0.165-inch wall thickness and a length of 10.350 inches, making them suitable for a variety of engine configurations.

These push rods are constructed from 4130 chrome moly steel, a material chosen for its good strength-to-weight ratio, which is important for high-RPM operation. The ends are meticulously formed with exact radii, and the overall concentricity is closely controlled to ensure consistent valve train geometry. They also feature a swedged end, which adds strength where it's needed most. For added durability and corrosion resistance, they are heat-treated and finished with a black oxide coating.

This set includes eight push rods, which is what you'll need for most V8 engines. Proper push rod length is critical for correct valve lash adjustment and overall engine health, so ensure you've verified this length for your specific application.
