I have seen a few variations of the new Gear Reduction Box's Has anyone tried the new UTV Solutions Gear Reduction box's or portal box as some say. From what I am seeing the GRB provides 4” of lift by moving the axle centerline upwards by 4” at the wheel hub, allowing for greater ground clearance under the axle center. By moving the axle centerline, we’re able to maintain factory positions and angle measurements on the upper and lower control arms, Axle shafts, and tie rods.
The GRB also provides a wider stance, adding approximately 3” to each side. The wider stance allows you to go over or around the well-beaten path left by other UTVs and ATVs
