What material are these push rods made from?

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

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

A swedged end means the end of the push rod has been shaped and reinforced, typically by compressing the material. This process improves the strength and durability of the connection point where the push rod interacts with other valvetrain components.

Are these push rods a direct fit for any engine?

These push rods are designed for specific engine applications where their dimensions (5/16" diameter, 8.650" length, 0.080" wall) and construction are required. It's important to verify compatibility with your specific engine build or manufacturer's specifications.

About this part

Product Details

In this set, you get 16 push rods, each measuring 5/16 inches in diameter, 8.650 inches long, with a 0.080-inch wall thickness. They're constructed from 4130 chrome moly steel, a strong material often used in performance engine components. These push rods feature swedged ends, meaning they've been shaped and reinforced for better durability and connection within the valvetrain.

Manley Performance paid close attention to the details with these push rods. The ends are meticulously formed with precise radii, and the company maintained excellent concentricity and closely controlled lengths across the set. This level of control is important for consistent valve operation. They've also been heat-treated and finished with a black oxide coating, which helps with wear resistance and provides a solid look.

When you're rebuilding or modifying an engine, the push rods are a critical link between the camshaft and the valvetrain. Ensuring they are well-made and have consistent dimensions helps the engine run smoothly and reliably. This set is a solid option for many performance engine builds where precise valvetrain geometry is key.
