What material are these push rods made from?

These push rods are constructed from 4130 Chrome Moly tubing, a strong and durable material often used in performance engine components. They are also heat-treated and finished with a black oxide coating.

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

A swedged end means the tubing has been compressed and shaped at the ends, creating a stronger connection point. This design, along with the exact radii formed on the ends, helps ensure accurate valve lift and consistent valvetrain geometry.

Are these push rods suitable for stock engines?

While these push rods are well-built and offer improved durability, they are often chosen for performance engine builds where increased valvetrain stress is expected. It's always best to confirm compatibility with your specific camshaft and cylinder head setup.

About this part

Product Details

Starting with 4130 Chrome Moly tubing, these Manley push rods are built for engines that need a reliable valvetrain. The 0.165-inch wall thickness adds strength, while the 7/16-inch diameter is a common size for many performance applications. Each push rod measures exactly 7.950 inches long, ensuring consistent geometry in your engine build.

Manley pays close attention to the details that matter for valvetrain accuracy. The ends are meticulously formed with precise radii, and the company controls for excellent concentricity and closely held length tolerances across the set. This means you get a well-built component that helps maintain proper valve lift and timing. They are also heat-treated and finished with a black oxide coating for added durability and corrosion resistance.

This set includes eight push rods, enough for a typical V8 engine. If you're rebuilding your top end or looking for a stronger push rod for a performance camshaft, these are a solid option.
