What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel, a strong and durable material often used in performance engine components. They are also heat treated for added toughness.

What does 'swedged end' mean for these push rods?

A swedged end means the end of the tube has been compressed or flared to create a stronger, more secure connection point. It helps ensure the push rod stays properly connected within the valvetrain.

What is the benefit of excellent concentricity and controlled length?

Excellent concentricity means the push rod is very round and spins true, while closely controlled length ensures each push rod is the correct size. Both are critical for smooth and consistent operation of your engine's valvetrain.

About this part

Product Details

Manley Performance is well-known for making strong engine components, and these push rods are a good example of that. If you're rebuilding or upgrading the valvetrain in your engine, these push rods are built to handle the job. They're made from 4130 chrome moly steel, which is a solid material for this application, and feature a wall thickness of 0.165 inches for good rigidity. The ends are meticulously formed with exact radii, and the overall length is closely controlled to ensure they work correctly in your engine. They also come with a black oxide finish for some added protection.

The swedged ends on these push rods are designed for a secure connection, and the heat treatment adds to their durability. Having excellent concentricity means they spin true, which is important for consistent valvetrain operation. This set includes eight push rods, which is what most common V8 engines require. They're a well-made part that should fit right into your build.
