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.

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

A swedged end means the end of the push rod has been compressed and shaped, typically to create a stronger, more integrated connection point for the rocker arm or lifter. This construction method helps ensure reliability.

Are these push rods suitable for a stock engine rebuild?

While these push rods are well-made and feature precise dimensions, their construction from 4130 chrome moly with specific end forming is often favored for performance or modified engine builds where valve train geometry is critical. Always consult your engine builder or performance specialist to ensure they meet your specific application needs.

About this part

Product Details

This set gives you eight Manley push rods, each measuring 3/8 inch in diameter with a 10.550 inch length and a 0.135 inch wall thickness. They are constructed from 4130 chrome moly steel and feature swedged ends, making them a solid choice for engine builds where precise valve train geometry is important.

Manley has paid close attention to the details here. The ends are meticulously formed with exact radii, and the push rods themselves exhibit excellent concentricity. This means they spin true and maintain their length very closely, which is crucial for consistent valve lift and timing. They’ve also been heat treated and finished with a black oxide coating for added durability and corrosion resistance.
