If you're into trailering, you know the struggle of mismatched hitch ball sizes. The CURT 21100 reducer bushing is a game-changer, letting you adapt a 3/4-inch shank ball to a 1-inch hitch hole. No more buying new balls just because your hitch changed!
The yellow zinc finish isn’t just for looks—it adds serious durability against rust and weathering. I’ve left mine exposed to rain and road grime, and it still looks brand new. Plus, CURT backs it with a limited lifetime warranty, so you’re covered if anything goes wrong.
Installation is stupid easy. Slide it into the hitch hole, insert your smaller ball, and tighten everything down. Some reviewers mentioned slight slop, but I paired mine with flat washers (as one savvy user suggested) for a rock-solid fit. Zero wobble during my 200-mile haul.
Real talk: This $10 part saved me from buying a whole new ball mount setup. It’s now a permanent resident in my trailering kit—because you never know when you’ll need to borrow a buddy’s trailer with different specs.
Downside? It won’t magically fix severely worn hitch holes (that’s on your equipment maintenance). But for standard use? Absolute gold. Pro tip: Buy two—they’re small enough to lose in your truck bed toolbox.
