Maximize your ATV’s performance at higher elevations with the EPI Performance WE437027 Sport Utility Clutch Kit, designed specifically for 2011–2014 Polaris Sportsman 550 EFI 4×4 models equipped with 27–28 inch tires. Engineered for elevations between 3,000–6,000 feet, this clutch kit restores lost power caused by both oversized tires and reduced air density, delivering smoother acceleration and improved throttle response.
