A little tight on the bearings

The bearing fit was a little tight, but it worked out fine. The rest of the hub is great. The steel is very thick and strong.

Fits Dexter System Perfectly

I needed a replacement for a Dexter hub and this one was a direct swap. The pre-installed races and studs were a huge bonus. It’s well-made and durable.

Exactly What I Needed

I was looking for a replacement hub for my 12K axle and this was the perfect fit. The specs were accurate and it installed without any problems. The pre-installed studs are great.

Heavy Duty and Reliable

I'm hauling a skid steer almost daily and needed hubs I could trust. These are super solid and the 8 on 6.5 bolt pattern is spot on. Very happy with the performance under heavy loads.

Great Quality and Price

The buy 4 for 15% off deal was fantastic. The hubs arrived quickly and the quality is excellent. I'm using an oil bath system, and these were ready to go. Can't beat the value.
