What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel. This material is chosen for its strength and durability, making it suitable for demanding engine applications.

What does the 'swedged end' mean?

A swedged end refers to a method of joining or reinforcing a tube by compressing or expanding the metal at the end. For these push rods, it contributes to the overall strength and integrity of the connection points.

What is the purpose of the black oxide finish?

The black oxide finish serves a dual purpose. It helps to improve the durability of the push rods by providing a layer of protection, and it also gives them a clean, finished appearance.

About this part

Product Details

Manley Performance is well-known for making strong engine components, and these push rods are a great example of that. If you're rebuilding or upgrading the valvetrain in your engine, these push rods are built to handle the job. They measure 5/16 inch in diameter with a 7.550 inch length and a 0.120 inch wall thickness, made from durable 4130 chrome moly steel for good strength and resistance to bending under load.

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 lift and timing. They've also been heat-treated and finished with a black oxide coating, which helps with durability and provides a solid look.

This set includes 16 push rods, which is what most V8 engines require. The swedged end design adds to their overall robustness. When you're putting an engine back together, using well-made components like these push rods is key to achieving reliable performance.
