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 means the end of the tube has been compressed and formed to create a stronger, more precise connection point. Manley forms these ends with exact radii for excellent concentricity and controlled length.

Are these push rods suitable for a stock engine rebuild?

While these push rods are well-built and feature precise dimensions, they are often used in performance or upgraded engine builds. It's always best to consult with your engine builder or refer to specific build recommendations to ensure they are the right fit for your application.

About this part

Product Details

This set includes eight Manley Performance push rods, each measuring 3/8 inch in diameter with a 6.500 inch length and a 0.135 inch wall thickness. They are constructed from 4130 chrome moly steel, known for its strength and durability in high-stress engine applications. The swedged ends are meticulously formed with exact radii, ensuring excellent concentricity and closely controlled lengths for consistent valve train operation. These push rods are heat-treated and finished with a black oxide coating for added protection and a clean look.

When rebuilding or upgrading your engine's top end, push rods play a crucial role in transferring the motion from the camshaft to the rocker arms. Manley's attention to detail in forming the ends and maintaining precise length control helps ensure smooth and reliable operation of your valve train. The 4130 chrome moly material offers a strong yet relatively lightweight option, suitable for many performance builds where reliability is key.
