What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel, a strong and durable material often used in high-performance engine components. They are also heat-treated and finished with a black oxide coating.

What does 'swedged end' mean for a push rod?

A swedged end means the end of the push rod has been compressed and formed to create a stronger, thicker section. This design helps prevent flexing and improves the stability of the valve train under load.

Are these push rods a direct replacement for any stock part?

These push rods are designed with specific dimensions and features for performance applications. It's important to verify that the 3/8 inch diameter, 7.550 inch length, and 0.135 inch wall thickness match the requirements for your specific engine build.
