What material are these push rods made from?

These push rods are made from 4130 chrome moly steel, which is known for its strength and durability in engine applications. They are also heat-treated and finished with a black oxide coating.

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

A swedged end means the end of the push rod has been formed and reinforced, often with precise radii. This design helps ensure a solid connection and proper function with your valvetrain components.

Are these push rods a direct replacement for any stock part?

These push rods are designed for performance applications and may not be a direct replacement for all stock components. It's important to verify the specifications against your engine's requirements.

About this part

Product Details

In this set, you get 16 push rods, each measuring 5/16 inches in diameter with a 9.100-inch length and a 0.080-inch wall thickness. They are constructed from 4130 chrome moly steel, a well-known material for its strength and durability in high-performance engine applications. These push rods are designed with swedged ends, which are meticulously formed with exact radii for a precise fit and function within your engine's valvetrain.

Manley Performance pays close attention to the details that matter for engine components. You can expect excellent concentricity, meaning the push rod is uniform along its length, and closely controlled lengths from one rod to the next. This level of precision is important for consistent valvetrain geometry and reliable operation. The heat treatment and black oxide finish add to their resilience and help protect against corrosion.
