Mother Clutcher made as an OE style Polaris primary (aka drive) clutch made specific for 2014-2020 Sportsman 570 (all packages including X2 and ACE 570). This clutch is made just for Sportsman, unlike other aftermarket ones. We have spent a good amount of time testing and revising these clutches before selling them to make sure they have smooth and responsive performance on the 570. Guaranteed this comes correct for ready to bolt on and ride with weights and spring already in it! FITMENT: FITS ALL PACKAGES OF 2012-2020 Sportsman 570.* Manufacturer Part Number: 1323255 *This is the EBS style of clutch, which means it has a one way bearing which adds EBS (engine brake system) to some years that did not originally come with the feature. If you have certain L.E. models you already had this style clutch and it will perform the same as your stock one. If another year or package Sportsman 570 you will feel that upgrade, because it helps you slow down a little when you let off the gas which equals less wear on your brakes.
