Not just another hub! JOES Hubs feature many improvements over conventional designs. The rear seal slips easily into an O-ring sealed bore and is held in place by a retainer and allen screws. This system prevents the seal from slipping when the hub gets hot, eliminates leaks and allows repeated use of the seal. The floating rotor flange is drilled for 8-bolt rotors (add a T-Nut Set to float the rotor for maximum braking). Hub kit includes bearings, seal, spindle nut and studs. Just add the appropriate dust cover or drive flange to complete your assembly.
