What material are these push rods made from?

These push rods are constructed from 4130 chrome moly, a strong and durable material often used in high-performance engine components. They are also heat treated and finished with a black oxide coating.

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

A swedged end refers to the way the end of the push rod is formed or crimped. This method is used here to create precise radii and ensure excellent concentricity and controlled length, which is critical for proper valve train function.

Are these push rods suitable for a stock engine rebuild?

Yes, these push rods are designed for precise valve train geometry and are made from durable materials. Their exact dimensions and well-formed ends make them a solid option for both stock rebuilds and performance applications where accuracy is important.

About this part

Product Details

Manley Performance is well-known for making solid engine components, and these push rods are a great example of that. If you're rebuilding or modifying your engine's top end, precise valve train geometry is key. These push rods are designed to help you achieve that accuracy. They measure 5/16 inches in diameter and are 8.900 inches long, with a wall thickness of 0.080 inches, giving you a strong yet lightweight component.

What sets these apart is the attention to detail in their construction. The ends are meticulously formed with exact radii, which helps ensure excellent concentricity and closely controlled length from one push rod to the next. This level of precision is important for consistent valve lift and timing. They're made from 4130 chrome moly, a strong and durable material, and are heat treated with a black oxide finish for added protection.
