Question:
I have a Dexter axle on a boat trailer I need to replace. The Hub face is 72.5 and the spring center is 60.38. Tube diameter is 1 3/4. Hubs are 5 lug on 4.5 centers. Do you have a replacement with or without hubs?

Hey Edwin. The closest axle I have to those measurements is the Dexter Trailer Idler Axle w/ Hubs item # 20545I-EZ-72-10 or without hubs item # T20BTR-EZ-7258. These are 2,200 lbs axles, that have a 72" hub face, and spring seats mounted at 58". You'll be able to relocate the spring seats using two of the Spring Seat for Typical 2,000-lb, Round Trailer Axles with 1-3/4" Diameter item # TRSS175. These axles will be 1/4" shorter on both sides.
What happened to your axle?
