This rack just - like the vehicle - is rugged, versatile, and very cool. The outside frame is made of 1 inch tubing and the flooring with inch cold roll steel tubing. The rack includes two aluminum wind deflector one in the front and one on the bottom to avoid increased noise levels and drag. The installation is done directly to the factory mounts on the vehicle, all mounting hardware is stainless steel. The design follows the contours of the FJ roof while keeping the bottom level.
