What material are these push rods made from?

These Manley push rods are constructed from 4130 chrome moly steel. This material is chosen for its strength and durability, making it well-suited for high-performance engine applications.

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

A swedged end means the push rod material has been compressed and shaped at the end, creating a strong, integrated connection. This method is used here with meticulously formed radii for precise contact with other valvetrain components.

Are these push rods suitable for stock engines?

While these push rods are well-built and feature precise dimensions, their specific length and material are often chosen for performance builds. It's important to verify the exact length and specifications required for your specific engine application.
