Manley Race Master valves are designed and engineered to withstand the abuse of the track. Race Master valves are targeted by the bracket, drag, and oval track racers, or even those with modified street engines that are operating at engine speeds below 8,000 rpm. These valves are constructed from XH-426 material for the exhaust and NK-842 for the intake valves, making them the strongest valves in their class. Whether everything is on the line at the track, or you just enjoy your high performance car or motorcycle on the street, trust Race Master valves by Manley to keep you on the move. Order the model designed for your vehicle year/make and engine application.
