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.
The best materials in the industry are offered, including exclusive materials that competitors do not possess.
Stems are hard coated with .0002 thick chrome rather than a few millionths of flash.
Superior to competitors' puddled stellite, hard tips can crack and erode off the stem.
The valve head and underhead shapes have been at the forefront of the quest for improved flow since the late 1960s.
Each Manley valve is price targeted to specific markets to ensure the best possible value to the customer.
