What material are these push rods made from?

These Manley push rods are made from 4130 Chrome Moly steel, a strong and durable material commonly used in performance engine applications. They are also heat treated for added strength.

What is the significance of the swedged end?

The swedged end is a design feature that creates a secure and reliable connection point where the push rod meets other valve train components. It helps ensure consistent contact and reduces the chance of separation under stress.

What does 'excellent concentricity' mean for these push rods?

Excellent concentricity means the push rod is very round and the center axis is consistent along its length. This precision is important for maintaining accurate valve train geometry and smooth operation.

About this part

Product Details

These Manley push rods are constructed from 4130 Chrome Moly steel, a strong and durable material often chosen for performance engine builds. The 0.165-inch wall thickness adds to their rigidity, helping to prevent flex under high-stress conditions. Each push rod measures 7/16 inches in diameter and 11.950 inches in length, with swedged ends for a secure connection.

Manley pays close attention to the details that matter for engine components. The ends are meticulously formed with exact radii, and the company maintains excellent concentricity and closely controlled lengths across the set. This precision helps ensure consistent valve train geometry. The push rods are heat treated for added strength and finished with a black oxide coating to resist corrosion.

This set includes eight push rods, which is the standard quantity needed for most V8 engines. Having a well-matched set with precise dimensions is important for proper valve train operation and overall engine performance.
