Backed by our guaranteed-fit promise.
This premium kit pairs six threaded oil‑bath hubs with matching 12″ manual‑adjust electric brake assemblies to refresh or upgrade a triple‑axle trailer. Compatible with 5.2 K–7 K electric axles and 8 K hybrid configurations, it delivers smoother braking, longer service intervals, and cross‑brand interchangeability with Dexter, Alko, and Rockwell.
Verify hub/drum and brake sizes, torque wheel nuts to specification, and perform regular inspections for the safest performance.
