How to Measure Pop Up Camper Axle Diameter to Pick Out an Over-Under Axle Kit

Question:

Hi, I am trying to do a spring over conversion on a little pop up that I have. I think this is the correct kit that I need but I cant find the axle diameter for my camper anywhere? Its gross weight is only like 1250#, would this be the correct size to use? Thanks

The Dexter Trailer Springs Over-Under Conversion Kit # K71-384-00 that you referenced is designed for 2-3/8 inch diameter axles which is normally used on 3,500 lb axles.

You most likely have a smaller axle diameter than this like either 1-1/2 inch or 1-3/4, but you can get under your trailer to measure to be sure. I attached a picture that shows where to measure.

Feel free to email me back with the diameter of your axle if not 2-3/8 inches and we can piece together an over-under kit for your axles.
