Description
Older GMC 3500 pickup trucks may have the GM 10.5-inch Full-Float Rear Axle, which uses a four-piece double nut/double washer system for wheel bearing adjustment. In 1980, a newer single spindle nut was introduced with a solid key and retainer ring, and this design was used for all GMC pickup truck spindles in the years that followed. Both of these designs are compatible with this spindle model.
Manufactured from high-strength 1040 steel, this spindle is built to support heavy loads and towing. It features a precision-machined bearing surface that ensures a proper fit with wheel bearings and hubs. Whether you are using this for commercial fleet trucks, small pickup trucks, or GMC midsize trucks, our spindle provides the durability you need while supporting proper wheel positioning and reliable drivetrain performance.
