Question:
Do you make an over/under kit for 1-3/4” axles?

Hey Bob. I have a solution for you but they don't make a specific kit for a 1-3/4" diameter axle like they do with the 2-3/8" item # K71-384-00 you were looking at.
To make your own conversion kit for a single 1-3/4" diameter axle you will need one of the U-bolt kit Item # APUBR-10 and two of the spring seats item # TRSS175 you were looking at. The difference between these two parts and a kit like the Dexter item # K71-384-00 is that the spring seats will need to be welded to the axle tube as opposed to bolting.
What kind of trailer do you have and why are you needing to lift it?
