So this is one of the products that I sell. http://ftdcabs.com/polaris-ranger-xp900-xp-dirt-stoppers The new Ranger XP900 has some rather large openings in front of the rear wheels that collect everything the wheels throw at it. And is it ever a PITA to clean out.
Our dirt stoppers mount without any drilling and hardware comes with the product. 5 minutes and installation is complete.
