Abstract: A UTV portal axle system is disclosed, including a spindle with a housing for housing input and output drive gears coupled by one or more idler gears. The output drive gear is disposed lower than the input drive gear to provide additional ground clearance to the UTV. The king pin axis angle is substantially the same as that of a stock UTV, while maintaining a scrub radius of substantially one inch or less. This is accomplished by the lower control arm ball joint being located within a recess of the output drive gear. This allows the UTV to be properly controlled when driven at high speeds over rough or uneven terrain. The gears may be interchangeable to allow the gear ratio to be adjusted to be more suitable for use at various driving speeds. A method of changing the gear ratio is also disclosed.
