What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel, a strong and durable material commonly used in high-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 refers to a manufacturing process where the end of the tube is compressed and shaped, often creating a stronger connection point for the cup that contacts the lifter and rocker arm. This helps ensure the integrity of the push rod under stress.

Are these push rods suitable for a stock engine rebuild?

Yes, these push rods are a well-built option for both stock engine rebuilds and performance applications. Their precise dimensions and durable construction contribute to reliable valvetrain operation.

About this part

Product Details

Manley Performance is well-known for making solid engine components, and these push rods are a great example of that. If you're rebuilding your top end or looking for a reliable replacement, these 5/16 inch diameter push rods are built from 4130 chrome moly steel, which is a strong material for this application. They measure 6.350 inches long with a 0.080 inch wall thickness, giving them good rigidity.

What sets these apart is the attention to detail in their construction. The ends are meticulously formed with exact radii, and they maintain excellent concentricity with closely controlled lengths. This precision helps ensure proper valve train geometry and consistent operation. They're also heat-treated and finished with a black oxide coating for added durability and corrosion resistance.

This set includes 16 push rods, which is what most V8 engines require. Having a well-built set like this can make a notable difference in the smooth operation of your engine's valvetrain.
