Looking for Rebuild Kit for Blue Ox Ascent Tow Bar # BX4370  

Published 11/03/2026

Question:

Just wondering if you sell the rebuild kit for Blue Ox tow bars. I have a model BX4370 Ascent bar that is approaching 5 years old, and understand that at a minimum the nuts, bolts, washers, etc should be periodically replaced. TIA…

Hey Rick, welcome back! We do have the washer kit for your tow bar with the part # BLU46XR as well as a replacement swivel assembly part # BLU89ER but we don't have a complete rebuilt kit. Is there any play or movement in the arms that has developed over the past 5 years?
