New, never installed, Erlandson Performance (or EPI) Polaris Sportsman Performance Clutch Kit. This kit is designed to improve low to mid range acceleration that will enhance back shifting and throttle response. This kit also helps reduce clutch heat therefore decreasing belt slippage. This is designed for stock engine and exhaust operation at 0-2000 feet of elevation. It comes with a set of weights, an orange and red primary spring, a new secondary clutch helix, and a full sheet of directions. The instructions say it is only for 2001-2002 models but this should be applicable to 2001-2005 Sportsman 500 H.O. 4X4 models with EBS. The EPI part number is WE475005B and it is in stock and ready to ship. Please verify this will fit your exact year, sub model, clutch, elevation, and serial number before ordering. I am not responsible if it does not fit for you and it will still be yours. Absolutely No Returns/No Refunds/No Excuses. Thanks for looking.
