Valves - Manley Extreme Duty Valves
Manley Performance is universally acknowledged as the leading manufacturer of performance and racing valves in the world. The reason for Manleys overwhelming success is simple: QUALITY. We offer the best materials in the industry - exclusive materials our competitors do not possess. Our stems are hard coated with .0002" thick chrome rather than a few millionths of flash. Our hard tips are superior to competitors puddled stellite which can crack and erode off the stem. Our valve head and underhead shapes have been in the forefront of the quest for improved flow since the late 1960s. And always each Manley valve has been price targeted to specific markets to ensure the best possible value to the customer.
