FAST offers a variety of precision-machined, steel distributor gears for people using steel roller camshafts. These steel distributor gears feature a modern heat-treating and manufacturing process that makes them compatible with steel cams. Roller cams are made of either induction-hardened or carburized steel. Neither of these materials is compatible with the stock distributor gears. In the past, bronze distributor gears were used, but for street applications, the bronze gears wear at an excessive rate and have to be replaced on a regular basis. FAST now makes it possible to use a steel distributor gear that provides an OEM-style lifespan—without damaging the cam. Make sure you have the right distributor gear for your steel roller cam with FAST steel distributor gears.
