I have seen that reference to 2.25" in a chart (I think that was a typo... should be 2.125"), other listings say 2.125, but if you check the Tekonsha site, the 5606 is listed as 2.08".

The proof will be in the pudding! I will definitely report what I find.

Be sure to check actual outer bearing numbers that are already installed on your trailer before ordering new ones. On mine, I found that two of the half-axles were the heavier 6K hubs, as compared to the listed 5.2K hubs. For the 6K hubs, they need outer bearing 15123 and race 15245.


The inner bearing/race numbers are common between the two hubs. (bearing 25580, race 25520)

And, the National 413470 grease seal works nicely.
