Skid Row Off-Roads Top Prop supports your top over the seats and forces water to roll off the top rather than collect in it. Our Tonno Prop does the same thing at the rear. Together they make driving a quieter experience since the material is prevented from flapping in the breeze. They are both very simple to install and can be used with virtually any top or tonneau cover. Our Top Prop can also be used in virtually any soft topped vehicle with a front roll cage.
