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 well-suited for the demands of an engine's valve train.

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

A swedged end is a manufacturing process where the end of the tube is compressed and shaped. For these push rods, it helps create a strong, integrated connection point for the lifter and rocker arm, ensuring proper fit and alignment.

What is the benefit of the black oxide finish?

The black oxide finish serves a couple of purposes. It helps to improve wear resistance on the surfaces that contact other valve train components, and it also offers a layer of protection against corrosion.

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 the top end of your engine, these push rods are built to handle the job. They're made from 4130 Chrome Moly steel, which is a solid choice for durability and strength under the stress of valve train operation.

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 means they'll seat properly and work smoothly with your lifters and rocker arms. They also come heat treated and with a black oxide finish, which helps with wear resistance and corrosion protection.

This set includes eight push rods, enough for a typical V8 engine. The swedged end design is a common feature that helps ensure a secure fit and proper alignment within the valve train.
