I replaced all my original bearings and seats with this set and it came out fantastic! These are the very best bearings made in the USA. The grease seals are the finest I have ever seen and will order more then I change out the grease every 2 years. I highly recommend this full set. I put them on my Vanleigh Beacon 5th wheel with 8K axels. A perfect fit!
