Good used hub salvaged from 1950 Spartan trailer. This same hub was used on a lot of vintage trailers in the 1950's which had 6 lugs. It has surface rust on the exterior but the inner surfaces are still in good shape. Hub includes #1779 outer bearing with race, #2788 inner bearing with race, grease seal and grease cap. Hub is for Warner brand 12" x 2" brakes which have the 8-1/4" donut shaped magnet. Lug studs on hub are 7/16" fine thread. Overall diameter of hub is 13-3/8" x 6-3/4" high. Photos may be slightly different from actual hub but all are in comparable shape. The grease seal on this hub does not fit very tight so it has been discounted in price. PLEASE BE SURE THIS HUB WILL WORK FOR YOU BEFORE ORDERING IT. IF YOU HAVE QUESTIONS PLEASE CALL 765-473-8088 AND ASK FOR DAN.
