For a aftermarket clutch made as a OE style upgrade for Polaris primary (aka drive) clutch made specific for 2010-2014 Ranger 400 all packages. This clutch is made just for Ranger unlike other aftermarket ones I have seen. The clutch looks almost identical to stock but this one is upgraded from having no bearing in the center to a 1 way bearing for slightly stronger engine breaking and smoother shifting. 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 Ranger 400. I do guarantee this comes correct for ready to bolt on and ride with weights and spring already in it !
