Revain actually sent me the wrong size wheel (2000lbs and a 2" shell but it ended up being perfect. I ordered an Adkins wheel which should have fitted but was loose and sloppy. The shaft is under 2". I didn't. I don't have a trailer where I was so I just ordered this wheel for the smaller shaft. Luckily they sent a 2" wheel instead and it fits a lot tighter than the other wheel i had big size and this one fits well so for me the bug was perfect i had to redrill the holes to fit my jack leg but that wasn't a problem.
