RBS is proud to bring the racers the finest KB/New Century Olds gear drive on the market. This gear drive starts off with a billet alum. cover that is machined from 7075-T6 to exact tolerances giving the motor it's best chance for accurate cam timing. The gears are made from heat treated steel and are finish ground for complete concentricity. The gear set includes a dual keyway crank gear, a idler gear that has the outer race ground into it using a high speed roller needle bearing and a cam gear that uses a seven hole vernier to dial in cam timing. The gear drive includes a mounting hardware kit, thrust bearing and washers, woodruff keys, and adjustable timing pointer. The cam hub uses a massive .625" hex shaft to drive the fuel or oil pump. This gear drive is set up to be used on a raised cam KB Olds or New Century engine block. RBS can help supply the customer with the proper cam cover or pump extension.
