RBS carries a full supply of Fowler crank support/crank starter standoffs. For the racer that changes combinations or has something happen that makes them need just one spare RBS is here to help. The stands are made from billet one inch hex alum. and are tapped 7/16-14". Stands are sold each and the racer must specify length as well as quantity when purchasing. Six inch stands are useful on the crank support if the racer is running a Pioneer mag drive on a BBC to get the proper blower belt clearance in front of the mag drive.
