I am very pleased with my Dirt Warrior "The Vault" door kit for my Polaris General 4. They were delivered very quickly, and came packaged like they could survive a nuclear blast! The installation was extremely easy, with absolutely ZERO drilling or modifying anything! Total install time was around 2 hours, including making the final adjustments to make a perfect seal and fit. It appears that a lot of thinking and planning went into the design of this kit and it shows with a very easy and straightforward installation, great job guys! I have not had the machine out in bad weather yet, but there is no question it will be very dry inside the cab. Be prepared to lose a little shoulder room inside the cab if you're a bigger guy (I lost around 2 inches or so of shoulder room on each side) My only suggestion to improve the kit would be to include black mounting hardware instead of the bright sliver for a more factory, inconspicuous look. With that being said, they look fantastic on the machine, they will be a huge improvement in wet and cold weather and they were simple to install! Thanks guys!
