What material are these push rods made from?

These push rods are constructed from 4130 Chrome Moly tubing. This material is known for its strength and relatively light weight, making it a popular choice for performance engine components.

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

A swedged end is a design where the tubing is compressed and formed at the end, creating a thicker, stronger section. This helps to improve the durability of the push rod, especially under the stress of engine operation.

What is the purpose of the black oxide finish?

The black oxide finish is applied after heat treatment. It helps to improve the surface hardness of the push rod and provides a degree of protection against rust and corrosion.

About this part

Product Details

These Manley push rods are made from 4130 Chrome Moly tubing, a strong and lightweight material often used in performance applications. The tubing measures 3/8 inch in diameter with a 0.135 inch wall thickness and a length of 10.750 inches, providing a solid foundation for your engine's valvetrain. The ends are meticulously formed with exact radii and feature a swedged design, which adds strength where it's needed most during operation. This attention to detail ensures excellent concentricity and closely controlled length, critical for consistent valve timing and performance.

Each push rod in this set of eight is heat treated and finished with a black oxide coating. This treatment helps improve surface hardness and offers some protection against corrosion. The precise manufacturing process results in excellent concentricity and closely controlled length, which are vital for ensuring your valvetrain components work together smoothly and efficiently. These push rods are a well-built option for builders looking for reliable components for their engine rebuild or performance upgrade.
