What is the purpose of swedged ends on these pushrods?

Swedged ends are formed to create a precise radius and ensure excellent concentricity. This helps maintain consistent valve train geometry and reduces wear on components like lifters and rocker arms.

What does the 0.080 inch wall thickness signify?

The 0.080 inch wall thickness provides a strong yet relatively lightweight pushrod. This balance is important for high-RPM engine operation, helping to prevent flex and maintain valve train stability.

Are these pushrods suitable for stock engines?

While these pushrods are well-built and precise, they are often used in performance engine builds where exact valve train geometry is critical. It's best to confirm compatibility with your specific engine's camshaft and valvetrain components.

About this part

Product Details

Starting with 4130 chrome moly steel, these pushrods from Manley are built for serious engine work. The 0.080 inch wall thickness offers a good balance of strength and weight, crucial for high-RPM performance where valve train stability is key. They measure 8.125 inches long with a 5/16 inch diameter, a common size for many performance V8 applications.

What really sets these apart is the attention to detail at the ends. Manley forms them with exact radii and ensures excellent concentricity, meaning the pushrod is perfectly centered. This precise construction helps maintain consistent geometry in your valve train, reducing wear and ensuring reliable operation. They also come with a heat-treated and black oxide finish for added durability and corrosion resistance.

If you're rebuilding or modifying an engine where valve train accuracy matters, these pushrods are a solid option. They are designed to fit right and perform consistently, helping you get the most out of your engine build.
