Just bought a 2023 sportsman 1000xp but dont have it yet. Ordering all new garage products bushings to change out while it's still clean and grease all the bearings. I was wondering what style these are. Before I order from garage products it says I need to select "A" or "B" style. I dont know what that is, maybe either sealed or not sealed? Also, how have the newer sealed bushings been holding up??
