- The Tusk UTV Rear Bumper/Cargo Rack/Spare Tire Carrier is a perfect addition to your side by side. Designed to be bolted to your machine’s factory roll cage and utilizes existing chassis holes. Installation has been made simple, using common hand tools (outlined in detailed instructions). The heavy duty cargo rack increases storage space and perfect for adventure bags or coolers, when properly secured. The cargo rack’s laser-cut design incorporates multiple locations for nylon strap or bungee hooks. Another important feature is the spare tire mount, providing peace of mind when venturing out on the trail. Even the best of tires can have an occasional flat, so this is a must-have.
