What material are these push rods made from?

These Manley push rods are constructed from 4130 Chrome Moly steel. This material is chosen for its strength and relatively light weight, which is important for valve train performance.

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

A swedged end means the end of the tube has been compressed and formed to create a stronger, more precise connection point. For these push rods, it helps ensure excellent concentricity and controlled length.

What is the purpose of the black oxide finish?

The black oxide finish serves a dual purpose. It adds a layer of protection against corrosion and wear, while also contributing to the overall durability of the push rod in engine operating conditions.

About this part

Product Details

Starting with a 0.080 inch wall thickness and constructed from 4130 Chrome Moly, these Manley push rods are built for serious engine work. The material choice here offers a good balance of strength and weight, crucial for maintaining valve train stability at higher RPMs. Each push rod measures 3/8 inch in diameter and 7.825 inches in length, with swedged ends that are meticulously formed with exact radii. This attention to detail in the end forming helps ensure excellent concentricity and closely controlled length, which are vital for consistent valve lift and preventing premature wear.

These push rods are heat-treated and finished with a black oxide coating. This treatment process adds durability and helps protect against corrosion, keeping them in good shape even in demanding conditions. The swedged ends are a notable design choice, providing a solid connection point and contributing to the overall rigidity of the component. When you're rebuilding an engine or looking to upgrade your valve train, components like these push rods are fundamental to ensuring proper operation and longevity.
