What material are these push rods made from?

These push rods are constructed from 4130 Chrome Moly steel, a strong and durable material often used in high-performance engine components. They are also heat-treated and finished with a black oxide coating.

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

A swedged end means the end of the push rod has been compressed and shaped to create a stronger, more integrated connection point. This design helps maintain valve train geometry under load.

What is the benefit of excellent concentricity and controlled length?

Excellent concentricity means the push rod is perfectly centered along its length, and closely controlled length ensures consistency between all push rods. This precision is crucial for proper valve train operation, reducing wear and ensuring reliable performance.

About this part

Product Details

Manley Performance is well-known for making strong 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 demands of performance camshafts and valve springs. They measure 5/16 inches in diameter with a 0.120-inch wall thickness, offering a solid balance of strength and weight.

These push rods are constructed from 4130 Chrome Moly steel, a material chosen for its durability and ability to withstand the stresses of engine operation. The ends are meticulously formed with exact radii and feature excellent concentricity, meaning they are perfectly centered and consistent. This attention to detail ensures they seat properly in the lifters and rocker arms, contributing to a stable and reliable valve train. They are also heat-treated and finished with a black oxide coating for added protection.

This set includes 16 push rods, enough for a typical V8 engine. The swedged ends are designed to provide a secure connection point and help maintain valve train geometry under load.
