Video Transcript for All About the Curt Reducer Bushing for Ball Mounts

Hi, everybody, Andy here with etrailer.com. Let's take a real quick look together at this CURT Reducer Bushing for ball mounts. Now, this bushing is going to reduce the one-inch diameter hole in your ball mount platform so that it can accommodate a three quarter of an inch diameter hitch ball shank. And on your screen, I am including a photo, showing you how this is going to be easily installed. And this is going to resist rust with a zinc finish. And you might be wondering about the height of this bushing.

We've had a few of our neighbors ask in our Q and A section on this product page. So on your screen, I am including a photo of this bushing with a measurement line, showing you that this is 0.551 inches, in case that was information you we inchesre looking for. But this is from CURT, and again, this will reduce the one-inch diameter hole in your ball mount platform so that it can accommodate a three quarter of an inch diameter hitch ball shank. Well, that's gonna wrap up our real quick look today. I do hope that our brief time together was helpful for you.

Again, my name is Andy, thank you for joining me.

I received my replacement receiver today. Sounds as though you received the one I sent back. The reducer for the ball worked great and the height for the trailer was just right. I tested it out and it works perfect with a level ride. Thanks for your knowledgeable help. Your company does a great job on finding the right solution for the hitch somebody would buy. Give them a try and you won't regret it.

the bushing worked perfect and the receiver is the perfect height. As I said in the original review it is still working great.

by:
My tow bar pins were too small for the holes in my bumper. I used them as reducers to fill the tow points on a steel aftermarket bumper of a Jeep. The OD was nearly correct. I drifted them in,then drilled them out to accept tow pins. Worked well for that purpose.
by:
Perfect fit . Solid strong part, one piece.

Bushing makes it possible to use an 1 7/8 trailer ball on the larger bore hole used for a 2 inch trailer ball. Perfect fit on a Curtis 2 inch receiver.
