What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel, which is known for its strength and durability in performance engine applications. They are also heat treated and finished with a black oxide coating.

What does 'swedged end' mean for a push rod?

A swedged end means the end of the push rod has been compressed and shaped to create a stronger, more secure connection point. This is often done where the push rod meets the rocker arm or lifter.

Are these push rods suitable for all engine builds?

These push rods are designed for performance applications and feature precise dimensions and strong materials. It's important to verify that the 7/16 inch diameter, 10.075 inch length, and 0.165 inch wall thickness are correct for your specific engine build and components.

About this part

Product Details

This set includes eight Manley Performance push rods, each measuring 7/16 inches in diameter with a 0.165-inch wall thickness and a length of 10.075 inches. They are constructed from 4130 chrome moly steel, a strong material often used in performance engine components. The ends are meticulously formed with exact radii, and the push rods feature swedged ends for a secure connection.

Manley has paid close attention to the details with these push rods. They offer excellent concentricity, meaning the wall thickness is uniform around the entire circumference, and their lengths are closely controlled. This precision is important for consistent valve train geometry and reliable engine operation. The push rods are heat treated for added durability and finished with a black oxide coating to help resist corrosion.

When rebuilding or modifying an engine, the push rods are a critical link in the valve train. Ensuring they are well-made and precisely sized helps maintain proper valve lift and timing. Always refer to the manufacturer's installation instructions for specific details regarding their use in your application.
