What material are these push rods made from?

These push rods are constructed from 4130 chrome moly tubing, a strong and durable material often used in performance engine components. They are also heat treated and finished with a black oxide coating for added resilience.

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

A swedged end means the tubing has been compressed and shaped at the ends, creating a stronger, more robust connection point. This design detail helps prevent flexing under the stress of engine operation.

Are these push rods suitable for a stock engine?

While these push rods are well-built and feature precise dimensions, they are often chosen for updated or performance engine builds where valve train strength is a priority. It's always best to consult with your engine builder or a trusted mechanic to ensure they are the right fit for your specific application.

About this part

Product Details

Built from 4130 chrome moly tubing with a 0.080 inch wall thickness, these Manley push rods are made to handle the demands of an updated engine build. The 5/16 inch diameter and 7.175 inch length are common dimensions, but the construction details are where they really shine. Manley pays close attention to the ends, forming them with exact radii and ensuring excellent concentricity. This means they'll seat properly in your lifters and rocker arms, which is crucial for consistent valve train operation.

The heat treatment and black oxide finish add durability and corrosion resistance, helping these push rods stand up to the heat and stress inside your engine. The swedged ends are a smart design choice that adds strength where it's needed most, preventing flex under load. This set includes 16 push rods, enough for most V8 engines, and they are designed to fit right into your existing valve train setup.
