What material are these push rods made from?

These Manley push rods are constructed from 4130 Chrome Moly tubing. They are also heat-treated and finished with a black oxide coating for added durability and corrosion resistance.

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

A swedged end is a design where the tubing is compressed and shaped at the end, creating a stronger, more integrated connection. This helps prevent the end from deforming or separating under the stress of engine operation.

Are these push rods suitable for high-performance engines?

Yes, the 4130 Chrome Moly construction, precise dimensions, and heat treatment make these push rods well-suited for demanding engine builds where valvetrain stability is important.

About this part

Product Details

These Manley push rods are made from 4130 Chrome Moly tubing with a 0.135-inch wall thickness, giving them a solid foundation for your engine's valvetrain. The 3/8-inch diameter and 8.950-inch length are common dimensions, but it's the attention to detail in their construction that really matters for consistent performance. Each end is meticulously formed with exact radii, and the overall concentricity is closely controlled to ensure they seat properly and operate smoothly within your engine.

The swedged end design adds strength where it's needed most, and the push rods are heat-treated and finished with a black oxide coating. This process helps protect them from corrosion and wear, contributing to a longer service life. When you're rebuilding or upgrading your engine's top end, having push rods that maintain their length and shape under stress is crucial for proper valve operation and overall engine health.
