FLYWHEEL PARTS FOR BIG TWIN ALL YEARS (EXCEPT TWIN CAM 88)

Jims 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.
