What material are these push rods made from?

These push rods are constructed from 4130 Chrome Moly steel, a strong and durable alloy commonly used in performance 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 mechanically formed or crimped to create a stronger, more integrated connection point. This design helps prevent failure under the stress of engine operation.

Are these push rods a direct replacement for all engines?

These push rods have specific dimensions (7/16" diameter, 12" length, 0.165" wall) and are designed for certain engine builds. It is essential to verify that these specifications match your engine's requirements before installation.

About this part

Product Details

This set includes eight Manley Performance push rods, each measuring 7/16 inches in diameter with a 12-inch length and a 0.165-inch wall thickness. They are constructed from 4130 Chrome Moly steel, a well-known material for its strength and durability in high-performance engine applications. The ends are meticulously formed with exact radii, and the push rods themselves exhibit excellent concentricity and closely controlled length, which are critical for proper valve train operation.

These push rods are heat-treated and finished with a black oxide coating. The swedged ends are designed to provide a strong connection point, reducing the risk of failure under stress. This attention to detail in manufacturing ensures that each push rod meets precise specifications, contributing to a well-functioning and reliable engine build. When rebuilding or modifying an engine, using push rods with consistent dimensions and strong end formations is key to achieving optimal performance and longevity.
