1977 and newer Chevy / GM D44 bearing hub, 6x5.5 wheel pattern without the rotor. Very commonly used on six lug conversions, and a stock application on Chevy / GMC. Includes races.
If you have a 1976 and older Chevy / GM Dana 44, you will need to change out the spindle to our large bearing spindle, PM706570X-NB, for this hub to work. This is because the 1976 and older spindle uses a smaller inner bearing. The quickest way to know what spindle you have is to check the OD of the spindle where the inner bearing rides. If spindle has a 2" OD where the inner bearing rides, you have the large bearing spindle. If the spindle has a 1.78" OD where the inner bearing rides, you have the small bearing spindle and will need to get a new spindle with this hub.
