Seems to Work Fine, Time Will Tell

Replaced a worn-out set with these. Everything installed without a hitch and the hub spins freely. The quality seems good, but the real test is how they hold up over time.

Excellent Kit for a Hub Rebuild

The 387A and 25580 bearings were exactly the right ones. The BLK seal is a quality piece, much better than the generic seals I've used before.

Solid Bearings, Decent Price

Used this for a 9k axle on a flatbed trailer. The bearings are definitely heavy-duty. The seal seems to be holding up well so far.

Perfect for a 10K Axle

The bearings were the correct size and the seal has been holding up perfectly after several hundred miles. Great all-in-one kit.

Solid Bearings, Confident Performance

Used this kit to rebuild my axles before a long cross-country haul. The bearings felt substantial and the seal went in without a fight. Peace of mind for the long road.
