What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel, a strong and durable material commonly used in performance engine applications. 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 reinforced and shaped with specific radii. This design helps to strengthen the ends, making them more resistant to wear and deformation under the stress of engine operation.

Are these push rods a direct replacement for stock parts?

These push rods are designed for performance applications and may not be a direct replacement for all stock components. It's important to verify the specifications and compatibility with your specific engine build and camshaft requirements.
