actually it does..up to a point..last season several guys reported polaris warranting their tunnels after buckling them...anytime you ever have an issue you think might be warranty..ask the dealer to contact polaris and ask for help..polaris is actually pretty good about stepping up if its not fragrant abuse...or shows signs of mods......I personally have had good treatment from polaris both personally and on customer rigs....
Yeah, I was one of those several guys, tunnel bent right at the brace above the rear drop bracket...spent 5 months dealing with Polaris...I wouldn't hold your breath if you're planning on getting a warranty for the tunnel under any circumstances...
