According to Dexter, this is a 3,750 lb torsion axle with a 90.3" hub face measurement. More than likely your axle uses # L68149 and # L44649 bearings with a # 168255TB grease seal. You will need to verify this information since Dexter did not have it available. Assuming that is correct, we have the following parts available depending on what you need:
-Trailer Idler Hub Assembly # AKIHUB-545-35-K
-Trailer Hub and Drum Assembly # AKHD-550-35-K
-Electric Trailer Brake Kit # AKEBRK-35-SA
-Dexter Disc Brake Assembly # T10HREKITBB
I'm not sure if you don't have brakes, have electric drum brakes, or disc brakes so I included replacements for all possibilities. If you were looking for different replacement parts please let me know and I will see what we have available.
