What material are these push rods made from?

These Manley push rods are constructed from 4130 chrome moly steel, a strong and durable material commonly used in performance engine components. They are also heat-treated and finished with a black oxide coating for enhanced resilience.

What do the 'swedged ends' mean?

Swedged ends refer to a manufacturing process where the end of the tube is shaped or compressed to create a stronger, more secure connection point. This design helps ensure the push rod maintains its integrity under the stress of engine operation.

Are these push rods sold individually or as a set?

The Manley Performance push rods, part number 25151-8, are sold as a set of eight. This is a common quantity for many V8 engine configurations.
