Valve Guides
They are precision-machined from high quality Manganese Bronze material.

These guides in combination with our low friction black nitrided valves provides the best solution for performance and durability.

For Exhaust guides for high powered engines that need a better thermal transfer coefficient, we use a copper alloy. Copper has about 3 times higher thermal transfer than Manganese Bronze.
