Upgrade your trailer's braking system with this complete 7,000 lb axle brake and drum kit from Trailer Supplies. This set combines a pair of high-performance 12"x2" self-adjusting electric brake assemblies with two fully equipped hub drums featuring an 8 on 6.5" bolt pattern and 9/16"-18 pre-installed studs and lug nuts. Each brake assembly (left and right) comes pre-wired and fully assembled with premium brake shoes, magnets, and springs on a heavy-duty backing plate. The drums are pre-greased and factory-prepared with a 25580 inner bearing and 10-225 grease seal pressed in, while the 14125A outer bearing is included and seated loose inside the drum for quick final assembly. Additional hardware includes 10 brake mounting nuts and lock washers, 2 dust caps with rubber plugs, 2 plastic hub covers, 2 castle nuts, flat washers, D washers, tang washers, and cotter pins. Finished with a durable black coating for enhanced corrosion resistance, this kit is compatible with most 7K trailer axles from Dexter, Lippert, AL-KO, Rockwell, and more—ideal for utility trailers, livestock haulers, campers, and heavy-duty towing needs. OEM Cross-References: Brake Assemblies replace Dexter part numbers K23-464-00 (Left) and K23-465-00 (Right). Hub drums are equivalent to Dexter 008-219-04 and 22004K.
