Dexter Nev-R-Lube Trailer Hub & Drum 008-385-82. I have a number of New Old Stock Dexter Nev-R Lube Trailer hubs for sale. They are 12" drums with 1/2" studs. 8 lugs an a 6.5" bolt circle. They fit a 50MM axle. I believe they were often used on Air Stream Trailers with the never lube system. The have the bearings & snapring installed but do not include the outer dust cap. Price is for one hub/bearing assembly. (I may have one hub with 9/16" studs or no studs as well, but most are 1/2" )
