What material are these push rods made from?

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

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

A swedged end means the tubing has been compressed and shaped at the ends. This process adds material thickness and strength to the ends of the push rod, where they connect to the lifters and rocker arms.

Are these push rods suitable for stock engines?

These push rods are designed with precision and durability in mind, often used in performance or rebuilt engines. While they can be used in stock applications, their specifications are beneficial for engines where valve train accuracy is critical.

About this part

Product Details

If you're rebuilding the top end of your engine, getting the push rods right is crucial for proper valve train geometry and performance. These push rods from Manley Performance are built for engines where precision matters, ensuring your valves open and close exactly when they should.

Crafted from 4130 chrome moly tubing, these push rods offer a strong foundation for your valve train. They feature meticulously formed ends with exact radii for excellent concentricity, meaning they're perfectly centered and straight. This close control over length and form is important for consistent valve lift and duration. The heat treatment and black oxide finish add durability and help protect against corrosion.
