What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel, a well-known material for its strength and durability in engine components. They are also heat-treated and finished with a black oxide coating.

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

A swedged end means the end of the push rod has been compressed and formed to create a stronger, more precise connection point. The ends on these Manley push rods are meticulously formed with exact radii for a reliable fit with your valve train components.

Are these push rods a direct replacement for all engines?

These push rods have specific dimensions (7/16" diameter, 8.600" length, 0.165" wall) and are designed for performance applications. It is important to verify these specifications against your engine's requirements or consult with a professional to ensure proper fitment.

About this part

Product Details

In this set, you get eight Manley Performance push rods, each measuring 7/16 inches in diameter with a 0.165-inch wall thickness and a length of 8.600 inches. These push rods are made from 4130 chrome moly steel and feature swedged ends, which are meticulously formed with exact radii for a precise fit. They are heat-treated and finished with a black oxide coating for durability.

The construction of these push rods is focused on accuracy and strength. They exhibit excellent concentricity, meaning they are perfectly round and balanced, and their lengths are closely controlled. This attention to detail helps ensure consistent valve train operation, which is crucial for optimal engine performance. The 4130 chrome moly material offers a good balance of strength and weight, while the swedged ends are designed for reliable connection to the rocker arms and lifters.

When rebuilding or modifying an engine, especially where precise valve train geometry is important, push rods like these play a vital role. Their well-built construction and controlled dimensions contribute to the overall reliability and efficiency of the engine's top end.
