What material are these push rods made from?

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

What does the 'swedged end' mean?

A swedged end is a manufacturing process where the end of the tube is compressed and shaped. For push rods, this typically creates a stronger, more precise connection point for the lifter and rocker arm.

What is the benefit of closely controlled length and concentricity?

Closely controlled length and concentricity are important for consistent valve train geometry. This precision helps ensure that each push rod functions identically, leading to smoother engine operation and potentially improved performance.

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. If you're rebuilding the top end of your engine, these push rods are built to handle the job. They're made from 4130 chrome moly, a solid material for this application, and feature a 0.120-inch wall thickness for added strength.

What sets these apart is the attention to detail in their construction. The ends are meticulously formed with exact radii, and they maintain excellent concentricity with closely controlled lengths. This precision helps ensure consistent valve train operation. They also come heat treated and with a black oxide finish, which helps with durability and corrosion resistance.

This set includes 16 push rods, which is what most V8 engines require. The swedged end design is a common feature that helps with proper seating in the rocker arms and lifters.
