What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel, a strong and commonly used material for 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 end of the push rod has been compressed and shaped, creating a stronger and more secure connection point. This design is often used in performance applications for added reliability.

Are these push rods sold individually or as a set?

This product is sold as a set of eight push rods, which is a standard quantity for most V8 engines. This ensures you have the correct number for a complete engine build or replacement.

About this part

Product Details

This set includes eight Manley Performance push rods, each measuring 7/16 inches in diameter with a 9.950-inch length and a 0.165-inch wall thickness. 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 themselves feature excellent concentricity and closely controlled length for consistent operation within your engine.

These push rods are heat treated and finished with a black oxide coating, which helps with durability and corrosion resistance. The swedged ends are designed for a secure connection. When rebuilding or upgrading your engine's valvetrain, using push rods with precise dimensions and solid construction like these is important for proper valve timing and lift.
