GEAR/PINION SHAFTS & HARDWARE FOR BIG TWIN & SPORTSTER

Weight: 0.04
We carry only USA made gear or pinion shafts and hardware. These are manufactured to exceed OEM specifications. Advanced features of all of our flywheel shafts include: special thread annealing to withstand extra nut torque, low friction 16 micron finish 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 flywheel shaft nuts now give the ultimate in flywheel holding power. The mating face of each nut has been ground to a 32 micron 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.
