What material are these push rods made from?

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

What is the purpose of the swedged end and exact radii?

The swedged end and meticulously formed radii on the ends of these push rods ensure they seat properly and make consistent contact with the lifters and rocker arms. This helps reduce wear and maintain smooth valvetrain operation.

What is the benefit of the black oxide finish?

The black oxide finish provides a layer of protection against corrosion and wear. Combined with the heat treatment, it helps these push rods withstand the demanding conditions within an engine.

About this part

Product Details

These Manley push rods are made from 4130 chrome moly tubing with a 0.135 inch wall thickness, giving them a solid foundation for your engine's valvetrain. The 3/8 inch diameter and 6.300 inch length are common dimensions, but the attention to detail in their construction is what really sets them apart. Each push rod is meticulously formed with exact radii on the ends, ensuring they seat properly in the lifters and rocker arms.

You'll appreciate the excellent concentricity and closely controlled length on these push rods. This precision means they'll operate smoothly and consistently, reducing wear on other valvetrain components. They're also heat-treated and finished with a black oxide coating, which helps protect them from corrosion and wear in the harsh environment of an engine. This set includes eight push rods, enough for a typical V8 engine.
