Howards Cams Distributor Gears are designed for high performance. These high-strength distributor gears come in two materials, bronze alloy and in limited applications, high strength composite construction. The bronze distributor gears are precision machined, with high-strength tooth designs that help minimize wear compared to OE bronze gears. The high strength composite gears utilize NASCAR-proven carbon fiber materials that provide precise timing and 300% more durability over bronze gears.
