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 durability, making it suitable for demanding engine applications.

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

A swedged end means the tubing has been compressed and shaped at the end, often to create a stronger connection point or a specific profile for valve train components. This design detail contributes to the overall reliability of the push rod.

Are these push rods suitable for a stock engine rebuild?

While these push rods are well-built and precise, their specifications (7/16 inch diameter, 0.165 inch wall) are often chosen for performance or modified engine builds. It's important to verify that these dimensions match the requirements of your specific engine's valve train geometry.

About this part

Product Details

If you're rebuilding the top end of your engine, getting the right push rods is crucial for proper valve train geometry. These push rods from Manley Performance are made from 4130 Chrome Moly, a strong and durable material that can handle the stresses of regular engine operation. They measure 7/16 inch in diameter with a 0.165 inch wall thickness and are 8.700 inches long, designed to work with many popular performance engine builds.

Manley pays close attention to the details with these push rods. The ends are meticulously formed with exact radii, and they maintain excellent concentricity, meaning they are perfectly round and balanced. This precision, along with closely controlled lengths, helps ensure consistent valve train operation. They are also heat-treated and finished with a black oxide coating for added durability and corrosion resistance.

This set includes eight push rods, which is what most V8 engines require. Having a well-built set of push rods like these can make a noticeable difference in the smooth operation of your engine's valve train.
