Dexter Trailer Hub Kit 008-393-91, 7,200 lb Capacity, 9/16 Inch Studs, Grease Lubrication with Cone Nuts

The Dexter 008-393-91 is a heavy-duty trailer hub kit rated for a 7,200 lb capacity, built for trailer axles using 9/16 inch wheel studs on a 4.75 inch pitch diameter. It is a grease-lubricated hub kit, meaning the bearing cavity is packed and sealed for grease service rather than an oil-bath design, and the kit includes the cone nuts needed to secure the wheel to the hub. This kit is compatible with hub part number 008-393-04, making it a straightforward match for trailers already built around that hub.

Because it is sized for 7,200 lb capacity axles, this kit suits mid-to-heavy tandem and single-axle utility, boat, and cargo trailers running 9/16 inch stud hubs. The grease lubrication design simplifies routine maintenance compared to oil-bath hubs, since service only requires repacking rather than monitoring an oil level or seal integrity for leaks. Installers replacing worn hub hardware or servicing a hub that takes 9/16 inch studs at a 4.75 inch pitch diameter can use this kit to restore the wheel-mounting hardware to factory-rated capacity.
