Let me tell you, this little yellow zinc-plated bushing is a game-changer for anyone who's ever struggled with mismatched hitch ball sizes. I was about to buy a whole new hitch setup until I discovered this $10 lifesaver.

The moment I slipped it into my 1-inch hitch hole, it transformed into the perfect adapter for my trusty old 3/4-inch ball. No more wobble, no more sketchy towing situations - just a secure fit that had me hauling my boat trailer with complete confidence.

What surprised me most was how durable this thing feels. That yellow zinc coating isn't just for looks - after several rainy trips and muddy roads, it still looks brand new. I keep one permanently in my trailering kit now, along with some flat washers (great suggestion from other users!) for extra security.

Sure, there's a tiny bit of play if you really look for it, but in actual towing conditions? Zero issues. Saved me from buying a new hitch system and let me keep using my favorite ball. For the price, this might be the most cost-effective trailer accessory I've ever bought.
