What material are these push rods made from?

These push rods are constructed from 4130 chrome moly tubing, a well-known material for its strength and durability in engine components. They are also heat-treated and finished with a black oxide coating.

What do the swedged ends do?

The swedged ends are a design feature that adds extra reinforcement to the push rod. This helps to prevent bending or failure, especially in high-performance applications with strong valve springs.

What is the benefit of closely controlled length and concentricity?

Closely controlled length and excellent concentricity mean these push rods are manufactured to very tight tolerances. This ensures consistent geometry and proper valve train operation, which is crucial for engine performance and reliability.

About this part

Product Details

These Manley push rods are made from 4130 chrome moly tubing, a strong and well-built material that holds up well under engine stress. The tubing measures 5/16 inches in diameter with a 0.080 inch wall thickness and a length of 8.150 inches, which are common dimensions for many performance engine builds. The ends are meticulously formed with exact radii, and the set offers excellent concentricity and closely controlled length, meaning they're made to precise specifications for consistent performance.

The swedged ends on these push rods add extra strength where it's needed most, helping to prevent bending or failure under heavy valve spring pressure. They're also heat-treated and finished with a black oxide coating, which helps with corrosion resistance and provides a clean look. This set includes 16 push rods, enough for a typical V8 engine.
