1. A vibration-reducing portal box assembly for mounting a wheel of an off-road vehicle, comprising:
a) a box housing having a receptacle adapted to receive a stock axle shaft of the off-road vehicle;
b) an output shaft operably connectable to the stock axle shaft received in said housing and effective to rotate upon rotation of said stock axle shaft; and
c) a wheel hub having a central opening adapted to receive said output shaft, and adapted to turn a wheel mounted to said wheel hub upon rotation of said output shaft;
wherein said output shaft has a proximal end portion having a first diameter, a distal end portion having a second, reduced, diameter, and a tapered portion connecting the proximal end portion to the distal end portion;
wherein the central opening of said wheel hub has a proximal end portion having a first diameter, and a distal end portion having a second, reduced, diameter, and a tapered portion therebetween to matingly receive the tapered portion of the output shaft;
wherein in the area where the diameter of the output shaft and the diameter of the wheel hub are reduced, the wheel hub supports the output shaft.
