A quick look at our RZR Turbo R 4 seat roof rack for our roll cage. We build our roof rack from 1.25x.095 DOM. The roof rack is radiused to match the ABF Turbo R 4 roll cage. We mount The roof rack to the structure of the Roll cage with four 3/16” thick tabs. This is strong enough to support just about anything you want. Spare tires, tents, bikes, kayak, and much more.
