What material are these pushrods made from?

These pushrods are constructed from 4130 Chrome Moly steel. This is a strong and durable material often used in performance engine components.

What does 'swedged end' mean for these pushrods?

A swedged end is a manufacturing technique where the end of the tube is compressed or expanded to create a stronger, more integrated connection. This design is common for pushrods to ensure strength at the points where they connect to the lifter and rocker arm.

What is the benefit of excellent concentricity and controlled length?

Excellent concentricity means the pushrod is perfectly centered along its length, and closely controlled length ensures it's exactly the right size. Together, these details contribute to a more stable and predictable valve train operation, reducing wear and improving performance consistency.

About this part

Product Details

If you're rebuilding the top end of your engine, especially for a performance build, you need pushrods that can handle the stress. These pushrods from Manley Performance are made from 4130 Chrome Moly steel, a strong material known for its durability under demanding conditions. They are designed to be a direct replacement for stock pushrods, ensuring a proper fit in your engine.

Manley pays close attention to the details with these pushrods. The ends are meticulously formed with precise radii, and they maintain excellent concentricity, meaning they are perfectly centered. This attention to detail helps ensure consistent valve train operation. They are also heat-treated and finished with a black oxide coating, which adds to their resilience and helps prevent corrosion.

This set includes eight pushrods, each measuring 7/16 inches in diameter with a 0.11400-inch length and a 0.165-inch wall thickness. The swedged end design is a common feature that helps with strength and proper seating in the lifter and rocker arm.
