Whether you’re getting brutalized by the sun in Arizona or dumped on by rain clouds in Oregon, Polaris ACE roofs are good to have. Polaris offers three types of OEM factory roofs: canvas roofs, one-part poly roofs, and the two-part Lock & Ride Sport Roof. Companies like QuadBoss and EMP make aftermarket door kits for the Polaris ACE as well. Dealers might try to convince you that polyethylene doors are inferior, especially with regards to high wind speeds. And while you can take the roof off when trailering on the highway to prevent it from falling off, unless you’re excessively speeding, a poly roof should stay snug as a bug on your trailer. If you’re a worry wart, you can always put a strap around the roof for safety. Attach one heavy-duty cable tie on each of the four mounting points and that roof ain't going nowhere. If you haven’t seen a plastic-roofed ACE on sled bed going 90mph down the interstate, you either ride close to home or don’t get out much.
