New front outer wheel bearing with race for one side only. Fits right or left side all 116, 123 and 126 chassis. This is a VERY common wear item on almost all 123 chassis I see come into the shop. Replace at 200,000 miles. Outers will wear out a lot faster than the inners. We also sell the inner individually or check our complete kit if you need everything. Unless you have the proper tools plan to take your hub to a machine shop to have the race pressed in. List price is $23.68
