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 mechanically formed or crimped to create a stronger, more integrated connection point. This design is intended to improve durability and ensure a solid fit within the valve train.

Are these push rods a direct replacement for all engines?

These push rods have specific dimensions (5/16" diameter, 7.600" length, 0.120" wall). You will need to verify that these measurements match the requirements for your specific engine build or application.

About this part

Product Details

This set includes 16 push rods from Manley Performance, each measuring 5/16 inches in diameter with a 7.600-inch length and a 0.120-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 exhibit excellent concentricity and closely controlled length, which are important for consistent valve train operation.

These push rods are heat treated and finished with a black oxide coating. The swedged ends are designed to offer improved durability and a solid connection within the valve train. For anyone rebuilding or modifying a performance engine, ensuring the push rods are well-made and precisely sized is key to proper valve timing and lift.
