Good product, minor packaging issue

The hub was rattling around a bit in the box, but arrived undamaged. Functionally, it's perfect and a great replacement for my old one.

Solid and Dependable

Running a small flatbed hauling lumber. These hubs have been rock solid under load. No complaints at all.

Solid build, races are a good fit

The quality of this hub is impressive for the price. The races were well seated, and it installed without a hitch on my utility trailer. Would buy again.

Exactly What I Needed

My old hub was shot. This one was an exact match. The studs feel strong and the bearing races are pressed in tight. Quick shipping too.

Smooth Rolling, Zero Problems

Replaced both hubs on my boat trailer. They've held up great so far, no play or wobble. The 5 on 4.5" bolt pattern matched my wheels exactly.
