Gears are made from heat treated steel and the gear set includes a single keyway crank gear set up for a SBC crank snout, a idler gear that has a high speed ball 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, as well as a woodruff key. The cam hub uses a industry standard .375" hex shaft to drive the fuel pump. This gear drive is set up to be used on a Donovan, Rodeck, Dart or most other aftermarket blocks.
RBS can supply fuel pump extensions and any other acc. you may need for the gear drive. The cam is raised .390" on the cam height.
