RCD has two systems to support the front end of your crank shaft, the rear bearing support which is built into RCD gear drive covers, and outboard crank supports which mount to the engine block and utilize stands and a bearing plate. Blown applications put extra strain on the end of the crankshaft which can lead to breakage of the crank snout and poor blower belt life. RCD has developed a support system to reduce the amount of force pulling up on the end of the crankshaft. Aluminum struts bolt to the engine block with four 1 1/4" stands which connect to a front plate and bearing housing to hold the end of RCD’s crank support hub (sold separately). Some assemblies have crank trigger slots machined into the struts. Configurations are available to use a RCD crank support with a crank mount starter.
