    made an easy change
  

*by P***N on Reviewed in the United States on November 24, 2020*

Since my camper only needed a 2 inch ball this bushing meant I didn't have to buy a new hitch.

### ⭐⭐⭐⭐ 







  
  
    Fits Loose
  

*by W***R on Reviewed in the United States on April 25, 2019*

Quite a bit of slop between bushing and hole in hitch.  Didn't have time before trip to do anything but use it.  Didn't have any problems.  YMMV
