1. A portal gear box assembly for an off-road vehicle that includes a driven shaft, the assembly comprising:
a housing that defines an first indent, an second indent, a third indent and a fourth indent;
a first gear subassembly comprising a first gear operably connected to the driven shaft, wherein the first gear subassembly is positioned within the first indent;
a second gear subassembly comprising a second gear operably connected to an output shaft, wherein the second gear subassembly is positioned within the second indent; and
the idler-gear subassembly comprising a removable adaptor and a third gear connecting the first gear to the second gear;
wherein the removable adaptor is selectively positionable in either the third indent or the fourth indent to change a position of the third gear in the idler-gear subassembly relative to the first gear and second gear, thereby permitting use of gears with different diameters and different numbers of teeth to alter a transmission ratio between the driven shaft and the output shaft.
