What material are these push rods made from?

These push rods are constructed from 4130 chrome moly tubing. This material is known for its strength and durability, making it suitable for high-stress engine applications.

What does the 'swedged end' mean?

A swedged end is a manufacturing process where the end of the tube is compressed and shaped. For push rods, this typically creates a stronger, more secure connection point for the lifter and rocker arm.

Are these push rods suitable for all engine builds?

These push rods have a specific length of 11.450 inches, a 7/16 inch diameter, and a 0.165 inch wall thickness. You'll need to verify these dimensions match your engine's requirements, especially if you've modified the camshaft or valvetrain.

About this part

Product Details

If you're rebuilding the top end of your engine, these Manley push rods are a solid option. They're made from 4130 chrome moly, a strong material that holds up well under the stress of valve train operation. The 0.165-inch wall thickness adds to their rigidity, helping to ensure consistent valve lift and timing.

Manley paid close attention to the details with these push rods. The ends are precisely formed with exact radii, and they maintain excellent concentricity. This means they'll seat properly in your lifters and rocker arms, reducing wear and ensuring smooth operation. They're also heat-treated and finished with a black oxide coating for added durability and corrosion resistance. The swedged ends are a common feature that helps them fit securely.

This set includes eight push rods, which is what most V8 engines require. Make sure to check your specific engine's requirements to confirm if this set is the right fit for your build.
