What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel, which is a strong and durable material 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 compressed and formed to create a stronger, more resilient connection point. This design helps prevent failure under stress, especially in higher-performance engine applications.

Are these push rods a direct replacement for all engines?

These push rods have specific dimensions (3/8" diameter, 7.775" length, 0.135" wall) and are designed for certain engine applications. It is important to verify these specifications against your engine's requirements to ensure proper fitment and function.

About this part

Product Details

This set includes eight Manley Performance push rods, each measuring 3/8 inch in diameter with a 7.775 inch length and a 0.135 inch wall thickness. They are constructed from 4130 chrome moly steel, known for its strength and durability, and feature swedged ends for added resilience.
