Very pleased with these hubs and bearings. Impressed with the quality. Packaging was great and included instructions. Installation was straight forward. In all honesty these could be priced much higher. Wheels now spin freely without wobble like the original harbor freight hubs. I have confidence now for highway trips (also upgrades the wheels).

I’ll update this in a year, but the hubs / seals / bearings all seem to be good quality. Would have been nice if there were a grease zerk on the backside of the hub, but no biggie. Everything went together great. On my particular install, I added bearing buddies and the fit was spot on.Edit - 6 months and still going strong.

Easy to install but the cap was thinner aluminum that dented during the install. Does the job though!

This was an exact fit for my Harbor Freight trailer. Everything you need at a reasonable price.

This product was fantastic because it comes with 2 sets of bearings for either a 1 inch or 1 and sixteenth axle! I was super unsure if this would work out but it worked perfectly! It makes it adaptation to you project specifically and it saved me so much time! The new pins they provide are expredinarily long and I couldn't get the silver cap to go on no matter what I tried so I just used my old cap and it worked great!

Was very happy with this product. The hub and accessories were exactly as described. Very good quality with excellent packaging (bearing sets were separated on separate cardboard tray with list of included parts right on the tray. Very nice! this was ordered when I had a problem receiving hubs on a previous order that got lost in delivery. ( from a different seller)
