What material are these push rods made from?

These Manley push rods are constructed from 4130 chrome moly tubing, which is known for its strength and durability. They are also heat-treated and finished with a black oxide coating for added wear resistance and corrosion protection.

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

A swedged end means the tube has been compressed and shaped at the end, creating a stronger and more integrated connection point. This design helps maintain the push rod's integrity under the stresses of engine operation.

Are these push rods suitable for stock engines?

These push rods are designed with performance in mind, featuring specific materials and construction details like swedged ends and precise length control. While they can be used in many V8 applications, it's always best to consult with your engine builder or refer to specific build recommendations to ensure they are the right fit for your particular engine setup.

About this part

Product Details

Starting with a 0.135-inch wall thickness and 4130 chrome moly construction, these Manley push rods are built for serious engine work. The 3/8-inch diameter and 8.250-inch length are common dimensions for many performance V8 applications, but it's the attention to detail in their formation that really matters. Each end is meticulously formed with exact radii, and the set boasts excellent concentricity and closely controlled lengths. This means they'll seat properly in your lifters and rocker arms, contributing to a more stable and consistent valve train.

These push rods are heat-treated and finished with a black oxide coating. This process helps to harden the surface, making them more resistant to wear, and the black oxide finish offers some protection against corrosion. The swedged ends are a smart design choice, providing a strong connection point and helping to maintain the push rod's integrity under the stress of engine operation. When you're rebuilding or modifying an engine, the small parts like push rods play a big role in overall performance and reliability.
