Fitment: (2016-2017) Polaris Ranger 900/1000 Crew. We have created and patented this new design to be a GREASABLE bearing while having 3 layers of protection to keep dirt, sand, mud, and water out. Our all new auto set angle & 2 Piece design will lower installation time dramatically. We are the ONLY COMPANY in the world with this design so don't waste your time with the copycats.
