I am getting ready to purchase a set of HD springs for my 2014 Sportsman 800. Not sure if I should go with the EPI, High Lifter, or the factory Polaris ones? The reason I want to upgrade to HD is because I plow with it, so I think that’d help the front out. I have a Wes Seat/box on the back rack. It squats a lot with a passenger on it. Stock just seem way too soft! Let me know what you put in your quad and why you like them! Thanks in advance!
