Smooth Rolling and Strong Braking

Used two of these hubs for a heavy equipment trailer. They roll very smoothly and the braking power is excellent with the new brake assemblies. A very solid piece of equipment.

Solid Upgrade for My Trailer

Replaced my old worn-out hubs with these. The pre-installed races saved me a ton of time and hassle. The quality feels very heavy-duty and the fit was perfect for my 12k axle. Brakes work like new now.

Perfect Interchange with Dexter

Bought this to replace a Dexter hub on my trailer, and it was a perfect fit. The part numbers match up, and the quality is excellent. No modifications needed, just bolted it on and went.

Seems Durable, Time Will Tell

Mounted these a couple weeks ago. So far, they are performing exactly as expected. The brake drum has good mass for heat dissipation. Installation was straightforward.

Exactly What I Needed for a Flatbed

I ordered two of these for my flatbed trailer rebuild. They arrived quickly and were exactly as described. The 8 on 6.5" bolt pattern lined up perfectly. No issues with installation at all. Great value.
