Advanced features of all of our sprocket shafts are special thread annealing to withstand extra nut torque, low friction 16 microfinish bearing surfaces, ultra hard 60-63 Rockwell finish, computer machined tapers that guarantee concentricity within .0003” and super tough, aircraft rated Durabar 60™ steel. Our sprocket shaft nuts now give the ultimate in flywheel holding power. The mating face of each nut has been ground to a 32 surface finish and held square to threads within .0005. This in turn will pull the shafts straight into the flywheels and simplify flywheel truing. We didn’t stop there! Each nut is machined on state of the art CNC lathes and heat treated to make these nuts the toughest and best available on the market. All these products combined give you the finest parts choice in the industry. Flywheel Model & Year Shaft Keys 45” models 1929/1973 65167 65151F Sportster 1957/1976(Rpls.
