A portal gear box assembly for an all-terrain vehicle includes a portal gear box housing with a set of gears contained therein, and a plurality of heat-radiating fins extending from the housing wall and effective to radiate heat from the housing at a faster rate than would be radiated in the absence of the fins. The fins may extend outward or inward from the housing, and may be formed integrally with one or more of the walls of the housing, or may be removably attached to the housing. Preferred fins comprise a generally rectangular, planer surface extending radially from a wall of the housing.
