What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel. This material is chosen for its good strength-to-weight ratio, making it suitable for performance engine applications.

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

A swedged end means the end of the push rod has been compressed and formed to create a stronger, more durable connection point. This method helps prevent the end from separating under stress and ensures precise contact with the lifter and rocker arm.

Are these push rods suitable for a stock engine rebuild?

Yes, these push rods are a well-made option for both stock engine rebuilds and performance applications. Their precise dimensions and quality construction contribute to reliable valve train function.

About this part

Product Details

These Manley Performance push rods are a solid option for your engine build. They measure 7/16 inch in diameter with an 8.050 inch length and a 0.165 inch wall thickness, designed for engines where precise valve train geometry is critical. Made from 4130 chrome moly steel, they offer good strength for their weight.

Manley paid close attention to the details here. The ends are meticulously formed with exact radii, and the push rods themselves show excellent concentricity with closely controlled lengths. This attention to detail helps ensure consistent valve train operation. They’re heat treated and finished with a black oxide coating for improved durability and corrosion resistance.

This set includes eight push rods, which is what most V8 engines require. If you're rebuilding your top end or looking for a well-made replacement, these push rods are a dependable choice.
