What material are these push rods made from?

These push rods are made from 4130 chrome moly tubing. This is a strong and commonly used material for performance engine components due to its durability.

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

A swedged end means the tubing has been compressed and shaped at the end, creating a stronger, more integrated connection point for the push rod cup.

What is the benefit of closely controlled length and concentricity?

Closely controlled length and excellent concentricity ensure that each push rod in the set is very similar. This consistency is crucial for smooth valve train operation and predictable engine performance.

About this part

Product Details

Manley Performance push rods are a solid option when you're rebuilding or upgrading your engine's valve train. This set includes eight push rods, each measuring 3/8 inch in diameter with a 0.135 inch wall thickness and a length of 9.750 inches. They are constructed from 4130 chrome moly tubing, a strong material commonly used in performance applications for its durability and resistance to bending under stress.

What sets these push rods apart is the attention to detail in their construction. The ends are meticulously formed with exact radii, which helps ensure proper contact with the rocker arms and lifters. You'll also find excellent concentricity and closely controlled lengths across the set, meaning each push rod is very similar to the others. This consistency is important for smooth valve train operation and predictable performance. They are heat-treated and finished with a black oxide coating, which helps with corrosion resistance and provides a clean look.
