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 performance engine components. They are also heat treated and finished with a black oxide coating for added longevity.

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

A swedged end means the end of the push rod has been formed and reinforced, often with a slight taper or bulge, to create a strong connection point. Manley forms these ends with exact radii for precise seating in your valvetrain components.

Are these push rods suitable for stock engines?

While these push rods are built with performance in mind due to their construction and specifications, they can be used in many applications where the correct length and diameter are required. It's always best to verify the specific length and diameter needed for your engine build.
