Hey Sam! Thanks for the picture of your axle tag. The correct bearing kit is the 15123/ 25580 Bearings, 10-36 Seal # BK3-100. If you want the equivalent from Dexter it is the # DX26ER.

Are you getting your trailer ready for an upcoming trip?

bearing kit fit as it should, I replace bearings, races and seals every year, don't forget the RED grease. I also keep the best used set in my tow bag for emergency use. can't win the race if you can't get the trailer to the track, E trailer for the win...Robin noted correct bearing kit above.
