SWING ARM BEARING KIT YFM250/YFM400

All Balls swing arm repair kits contain all of the bearings, shafts, seals and bushings required to rebuild a swing arm to factory specifications. The All Balls shafts are manufactured from 52100 steel for improved performance and extended life. The All Balls kits feature Teflon® coated washers in place of the thrust needle bearings. The Teflon® coated washer offers superior resistance to dirt, water and lack of lubrication which are all factors leading to premature failure.
