More About Manley Severe 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.

And always each Manley valve has been price targeted to specific markets to ensure the best possible value to the customer. The Manley Severe Duty ® series of valves is the Manley signature in the performance and racing industry. Exhaust material XH-428 and intake material NK-844 is offered by no competitor in the world.
