Replacement Hub for 2010 Triton Jet Ski Trailer  

Updated 02/03/2026 | Published 07/01/2024

Question:

I have a 2010 triton LTWCI jet ski trailer. Hubs have 44643 bearings. Bolt pattern is 5 on 4 1/2. What pre greased hubs and bearings do you recommend. Also, there’s no washers between the castle nut and bearing. Is this acceptable??

Hey Glenn, the bearing numbers you mentioned indicate that you have a 2k axle so for a hub with that capacity and the correct bolt pattern you'd want the part # 8-258-5UC1-EZ which comes pre-greased.

Hey Glenn, how did the pre-greased Dexter hub work out on your Triton trailer? Did it fit well with your existing bearings and bolt pattern? Your update could make it easier for the next person with the same setup.
