Our valve guides are precisely made of high quality manganese bronze.
The Supertech valve guides are designed to be used in conjunction with our valves with low-friction black nitrided material to provide the best solution in terms of both performance and durability.
In the case of exhaust valves designed for use in high power engines that require a better heat transfer coefficient, we use a copper alloy conductor. Copper has about three times higher heat transfer coefficient than manganese brown.
Whatever your needs, Supertech has the right valve guide for your application.
