What material are these push rods made from?

These Manley push rods are constructed from 4130 chrome moly steel. This material is known for its strength and durability, making it suitable for demanding engine applications.

What does 'swedged end' mean for a push rod?

A swedged end is a manufacturing process where the end of the tube is compressed and shaped. For push rods, this typically creates a stronger and more precise connection point where it contacts the rocker arm and lifter.

Are these push rods suitable for all engine builds?

These push rods are designed for engines where precise valve train geometry is important. Their controlled length and concentricity make them a solid option for performance builds or engine rebuilds where accuracy is key.

About this part

Product Details

If you're rebuilding the top end of your engine, getting the push rods right is key for proper valve train geometry. These push rods from Manley Performance are made from 4130 chrome moly, a strong and durable material that holds up well under the stresses of engine operation. They feature a swedged end, which is a common design that helps ensure a solid connection point.

Manley pays close attention to the details with these push rods. They're formed with exact radii on the ends for a clean contact surface, and they maintain excellent concentricity. This means they run true and straight, which is important for consistent valve lift and duration. The closely controlled length is also critical for setting up your valve train correctly, especially when you're working with different camshafts or cylinder heads. They come with a black oxide finish for a bit of corrosion resistance.
