2001 model is simple...undo 6 bolts around old hub, remove hub, slip new hub on and replace bolts (IIRC with new washers under them). No need to jack vehicle up, 10-15 mins each side tops. No need to touch anything else, the Extras that come included are for use in the earlier "semi automatic" mechanical hubs.

2002 Sporty , Ironman 2.5" spring, 2" body, 15 x 7 ROH wheels, K&N, 15 x 10.5 Simex Centipedes, Powerchip 91.
