One-Piece Construction Cuts Down on Rotor Runout

Separate rotors and hubs can trap rust or debris between mounting surfaces, which leads to uneven wear and brake pulsation once your trailer is back on the road. This 1-piece integral hub-and-rotor keeps both surfaces permanently aligned, reducing the chance of vibration showing up in your brake pedal or uneven pad contact during repeated stops.

Vented Rotor Handles Repeated Heavy Stops

Long downhill grades and repeated braking cycles build heat fast on loaded trailers. The vented 13-1/8" rotor moves airflow through the assembly to pull heat away during braking, which keeps pad wear more controlled and maintains more consistent braking feel on your hydraulic disc setup.

Drain Holes Reduce Moisture Buildup Inside the Rotor Hat

Water trapped inside your hub assembly after wet highway driving or boat ramp use accelerates corrosion where you usually can't see it. Integrated drain holes let moisture escape from the rotor hat section instead of sitting inside the assembly, which slows rust buildup and keeps your braking surfaces in better shape between service intervals.

Maxx Coating Holds Up Around Road Spray and Ramp Use

Road salt, standing water, and repeated washdowns wear through untreated metal fast on trailer brake components. The Maxx-coated finish adds corrosion protection across the hub-and-rotor assembly, giving your trailer more resistance to rust exposure during towing, storage, and repeated water contact.

Matches Common 7K Axle Bearing Combinations

Replacing a worn hub assembly gets complicated fast when bearing numbers and wheel fitment don't line up with your existing axle. This assembly fits 7,000-lb axles using 25580 inner bearings, 14125A outer bearings, and an 8 on 6-1/2" wheel pattern, which keeps your replacement focused on matching the hardware already under your trailer.
