What material are these push rods made from?

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

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

A swedged end means the tubing has been compressed and shaped at the end. This creates a stronger, more integrated connection point for the push rod, ensuring it stays securely in place within the valve train.

What is the benefit of precise length and concentricity control?

Closely controlled length and excellent concentricity are critical for proper valve train geometry. This ensures that the rocker arms and valves operate smoothly and consistently, which can lead to improved engine performance and reliability.

About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and these push rods are a great example of that. This set is designed for engine builds where precise valve train geometry is important. They measure 5/16 inches in diameter with a 0.080-inch wall thickness and a length of 8.450 inches, which are common dimensions for many performance applications.

These push rods are made from 4130 chrome moly tubing, a material chosen for its good strength-to-weight ratio, making them well-built for the demands of an engine. The ends are meticulously formed with exact radii, and the overall concentricity is closely controlled to ensure consistent valve train operation. They’ve also been heat-treated and finished with a black oxide coating for added durability and corrosion resistance. The swedged ends help ensure a solid connection within the valve train.
