What material are these push rods made from?

These push rods are constructed from 4130 chrome moly tubing. This material is chosen for its strength and durability in high-performance engine applications.

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

A swedged end means the tubing has been compressed and shaped at the ends. This creates a stronger connection point and allows for precise radii, ensuring a good fit against the lifter and rocker arm.

What is the purpose of the black oxide finish?

The black oxide finish serves two main purposes. It helps to protect the push rods from corrosion and provides a clean, finished appearance within the engine bay.

About this part

Product Details

These Manley push rods are made from 4130 chrome moly tubing with a 0.135 inch wall thickness, offering a solid foundation for your engine's valvetrain. The swedged ends are meticulously formed with exact radii, ensuring they seat properly against the lifters and rocker arms. This attention to detail helps maintain consistent geometry throughout the engine's operation.

You'll appreciate the excellent concentricity and closely controlled length on these push rods. They are heat-treated and finished with a black oxide coating, which helps with corrosion resistance and provides a clean look. Having a matched set of eight ensures that each cylinder receives the same push rod length and diameter, which is crucial for proper valve timing and lift.
