The SJPK-721 series replaces OEM hubs and with fewer parts, no finger guard of finger guard plate, the SJPK-721 mounts in the same footprint and bolt pattern as the OEM hub. The bearings are upsized to deliver twice the radial load capacity of OEM bearings, making the hub run stronger and longer. All units are pre-lubricated and sealed in our factory, thus requiring no additional lubrication.
