The Super ATV Polaris RZR XP Cooler is made for 2016 models and newer. It will fit XP, XP Turbo, and Turbo S two and four-seat versions. It has a 30-liter capacity with outside dimensions of (L x W x H): 22-3/8” x 20-7/8” x 12-1/2” and inside dimensions of (L x W x H): 15” x 16-7/8” x 7-3/8”. It is fully insulated and it will hold ice for 24 hours without issue. We tested it well the first day we installed it.
There is a lot of quality built into this cooler with rubber gaskets to make this waterproof and a nice sealed drain. The top is held down with two rubber straps. The installation takes about 10-minutes and it sort of uses the Polaris lock and ride mechanisms, but it is slightly modified. Once it is bolted together, you can remove the cooler in about 20-seconds.
This is marketed as a cooler because of the insulating properties, but it will work great for storage. In our case, we will most likely be using it for both a cooler and storage, depending on where we are riding and our needs at that time. The options with this cooler are endless.
One of the reasons we were drawn to this cooler is because it fits perfectly under our Assault Industries Adventure Rack. This too gives us more options as we can store items above and below the rack without issue. With our high mount Factory UTV Tire Carrier, we have the option to load up the machine as needed for any trail condition or duration.
