What material are these push rods made from?

These push rods are made from 4130 chrome moly tubing. This is a strong and durable material commonly used in performance engine components.

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

A swedged end means the tubing has been formed and compressed at the ends. This creates a stronger, more integrated connection point where the push rod meets the lifter and rocker arm.

Why is push rod length so important?

Correct push rod length is critical for establishing proper valvetrain geometry. It ensures the rocker arm pivots correctly, leading to accurate valve lift and consistent engine operation, especially after engine modifications.

About this part

Product Details

Manley Performance push rods are a well-built component for your engine's valvetrain. This set features 7/16 inch diameter push rods with a 0.165 inch wall thickness and a length of 10.750 inches. They are constructed from 4130 chrome moly tubing, a strong material often used in performance applications for its durability and resistance to bending under stress.

These push rods have swedged ends, meaning they are formed to create a stronger connection point where they meet the rocker arms and lifters. The ends are meticulously formed with exact radii for excellent concentricity, ensuring they seat properly and operate smoothly within the valvetrain. They are also heat-treated and finished with a black oxide coating, which helps with corrosion resistance and provides a clean look.

This set includes eight push rods, which is the standard quantity needed for most V8 engines. Proper push rod length and diameter are critical for correct valvetrain geometry and consistent valve lift, especially when you've made modifications to your engine's heads or camshaft.
