General RZR Discussion Help identify cargo/cooler box August 12, 2015 Purchased this off of eBay as a "demo" unit, seller listed the part number as Polaris 2880018, and according to Polaris’s website this part number should fit my 2015 XP 4 1000. Unfortunately it does not, any help? Thanks! Greg Attached Thumbnails Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
