Works great to reduce the hole size in your hitch to fit any size ball shank,good solid fit with these bushings,a must have,a lot cheaper than another hitch,really like them.

Great buy!
I've been looking for a receiver for months that had a 3/4 inch shank to absolutely no avail from any stores at all. So when I found this that allowed me to convert a 1 inch shank down to fit the ball I already owned. It is amazing how well it worked!

Excellent adapter to keep me towing.
Well, it's round, properly sized, seems to have an anti corrosion plating, and wasn't an arm and a leg.Works for me. I've had a Convert-a-Ball stainless for well over a decade on my truck. When I switched to a jeep and lifted it, I needed a drop hitch. This adapter let me use my 3/4 shank in the 1 inch drop hitch hole. Fit was perfect.
