The RZR Trail Desert Roof from Razorback Offroad is made from Military Grade 1/8" Thick Aluminum and reinforced in all the right places with internal strengthen ribs along the sides. This not only strengthens the roof it also helps to reduce those annoying noises known as the "oil canning effect". There is nothing like being a day out on the trail with squeaks and rattles that end up ruining the experience. We also designed in a full width overhead shelf to give that little extra space
