10K 9-123 Hub/Drum Oil Bath

Miller Auto Tech 99-86510-43 (or 99-86510-123) hub and drum assembly is built for 9,000-10,000 lb general duty trailer axles after July 2009. This post-2009 version uses 9-123 bearings with an 8 on 6.5 inch bolt pattern and 5/8 inch studs. Designed as a direct replacement for Dexter axles, it offers superior stopping power and durability for utility, cargo, and boat trailers. Oil bath design promotes even lubrication and longevity in heavy use.
