Upgrade your trailer's braking system with this complete 7,000 lb axle brake and drum kit from Trailer Supplies, combining high-performance self-adjusting electric brake assemblies with fully loaded 12"x2" hub drums. Each set includes one left-hand and one right-hand electric brake assembly, both pre-installed with brake shoes, magnets, and springs on a durable backing plate—pre-wired and ready to bolt on. The hub drums feature an 8 on 6.5" bolt pattern with 1/2"-20 studs and lug nuts already installed, and are finished with a protective black coating for long-term corrosion resistance. Each drum comes pre-greased and includes the 25580 inner bearing and 10-225 grease seal pressed in, along with the 14125A outer bearing sitting loose in the drum. All necessary hardware is included for a complete axle rebuild: dust caps with rubber plugs, 2 plastic hub covers, castle nuts, flat washers, D washers, tang washers, and cotter pins. This kit is compatible with Dexter, Lippert, AL-KO, Rockwell, and other major axle brands using standard 7K configurations. Ideal for utility, livestock, camper, and heavy-duty trailers, it's the all-in-one solution that saves time, parts-hunting, and ensures a safer, smoother ride.
