Question:
I am looking for U bolts for a Dexter axle. The sticker has 2 part numbers, 358264 and 3631962. The axle is 3 in diameter. The bolt diameter is 1/2 and the length is approximately 7. I need 4 sets for 2 axles.

Hey Ron, thanks for the information! For replacement u-bolts you'll need the U-Bolt Kit for Mounting 5,200-lb to 7,000-lb, Round Trailer Axles - 7" Long U-Bolts item # APUBR-8. This will give you 4 u-bolts, plates, and bolts to get your axles mounted on your trailer.
I have linked an installation video below so you can see how to get them set up. What kind of trailer do you have?

Hey Ron, how did the U-bolt kit work out for your Dexter axles? Did the fit and hardware line up the way you needed for both axles? Your update could make it easier for the next person with the same setup.
