What material are these push rods made from?

These Manley push rods are constructed from 4130 chrome moly steel. This material is known for offering a good balance of strength and light weight, making it suitable for performance engine applications.

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

A swedged end means the end of the tube has been compressed and shaped, creating a stronger, more integrated connection point. This design helps ensure the push rod stays securely connected to the lifter and rocker arm.

Are these push rods suitable for all engine builds?

These push rods are a well-built component for performance engine builds where precise valvetrain geometry is important. Always confirm compatibility with your specific engine and valvetrain components before installation.

About this part

Product Details

This is a set of 16 Manley Performance push rods, measuring 5/16 inches in diameter with a 0.080 inch wall thickness and a length of 9.150 inches. They are made from 4130 chrome moly steel and feature swedged ends. Push rods are a critical link in your engine's valvetrain, transferring the motion from the lifters to the rocker arms, which in turn open and close the valves. Ensuring accurate and consistent movement here is key to proper engine operation and performance.

Manley builds these push rods with attention to detail. The ends are meticulously formed with exact radii, and they hold excellent concentricity with closely controlled lengths. This precision helps ensure smooth operation and reliable valvetrain geometry. They are heat treated and finished with a black oxide coating for improved durability and corrosion resistance. The 4130 chrome moly material offers a good balance of strength and weight for performance applications.
