Manley Performance is universally acknowledged as the leading manufacturer of performance and racing valves in the world.

The reason for Manley’s overwhelming success is simple: QUALITY.

They offer the best materials in the industry – exclusive materials their competitors do not possess.

There stems are hard coated with .0002″ thick chrome rather than a few millionths of flash.

There hard tips are superior to competitors’ puddled stellite which can crack and erode off the stem.

There valve head and underhead shapes have been in the forefront of the quest for improved flow since the late 1960’s.

And always each Manley valve has been price targeted to specific markets to ensure the best possible value to the customer.
