What material are these push rods made from?

These push rods are constructed from 4130 chrome moly tubing, a strong and reliable material commonly used in performance engine components. They are also heat-treated and finished with a black oxide coating.

Why is push rod length and concentricity important?

Precise length and concentricity are crucial for establishing correct valve train geometry. This ensures consistent valve lift and timing across all cylinders, contributing to smooth engine operation and optimal performance.

What is the wall thickness of these push rods?

These push rods have a wall thickness of 0.080 inches. This provides a good balance of strength to handle engine forces without adding unnecessary weight.

About this part

Product Details

If you're rebuilding the top end of your engine and need to ensure your valve train geometry is spot on, a quality set of push rods is essential. These push rods from Manley Performance are built from 4130 chrome moly tubing, a strong and reliable material for this application. They feature a 0.080 inch wall thickness, offering a good balance of strength and weight for consistent performance.

Manley pays close attention to the details with these push rods. The ends are meticulously formed with exact radii, and they maintain excellent concentricity with closely controlled lengths. This precision helps ensure that each push rod functions identically, contributing to a well-behaved valvetrain. They are also heat-treated and finished with a black oxide coating for added durability and corrosion resistance.

This set includes 16 push rods, which is what most V8 engines require. Having a matched set like this is important for achieving optimal valve lift and timing across all cylinders.
