For a aftermarket NON EBS clutch made as a OE style Polaris primary (aka drive) clutch made specific for 2015-2020 Polaris Scrambler XP 1000 . It also fits 2017+ Sportman 1000 Highlifter edition . This clutch is made just for Scrambler 1000 unlike other aftermarket ones I have seen. I have spent good amount of time testing and revising these clutches before selling them to make sure they have smooth and responsive performance on those 1000 models. I do guarantee this comes correct for ready to bolt on and ride with weights and spring already in it ! Direct aftermarket replacement for oem part numbers 1323123 and1323378 . Those are the 2 Non EBS applications that are same as this. ALTERNATIVE FITMENT:This can also be used on all Sportsman 1000 and Scrambler 10000 EBS models to reduce the amount of engine breaking when you let off the gas. Oem EBS clutches on those was 1322953 , 1322814 and 1323377.
