As a result of CURT innovation and engineering genius, Switch Balls offer the ultimate in convenience and reliability for a variety of light-duty and medium-duty towing applications. Essentially, a CURT Switch Ball is a trailer ball shank with a removable head. With its exclusive J-groove design, the Switch Ball trailer ball allows different heads or ball sizes to be places on the shank for accommodating different coupler sizes. This means there is no need to switch between ball mounts or even to own a second ball mount to fit an additional trailer. When you need to make the switch, simply twist the Switch Ball head, lift it off and twist on another. The J-groove ensures a solid hold on your trailer, while still allowing for easy removal of the trailer ball without tools or pins. This CURT Switch Ball trailer ball set comes with two ball attachments. Ball 1 features a ball diameter of 1-7/8" and ball capacity of 3,500 lbs. Ball 2 has a 2" ball diameter and a ball capacity of 6,000 lbs. Ball 3 has a 2-5/16" diameter and a ball capacity of 8,000 lbs. The shank measures 2-1/4" long and 1" in diameter. We construct these interchangeable hitch balls from premium-grade steel for strength and give them a bright nickel-chrome finish for a long life. To ensure your safety and provide you with a tow ball you can depend on, CURT Switch Balls are independently tested in accordance with SAE J684.

Update:So nearly two years later, this system still works great for me. Used it to haul a 18' trailer over 300 miles to move house, for hauling building supplies about a half dozen times or so, and to haul firewood about 2000lb at a time last winter.I had to take a little sand paper to the grooves because I let it sit out over the winter unprotected and the ball didn't want go back on, but it only took a minute to fix, and it was really my fault for not taking better care of it. All the balls swap on and off without a hassle. Just keep it greasy or oily and you won't have a problem.Original review:Background: I bought this for my 2000 Durango (aka Dr. Derango / The Dr.) because the previous owner(s) let the hitch rust-weld itself into the receiver. I'm sure I'll find a way to rip it out some day, but in the meantime I just wanted a quick change system to pull things without a lot of hassle.The good:No moving parts: The Reese system uses too many little parts that move (springs, ball bearings, etc) that are just asking to gum up. The Reese I bought before this was defective out of the package, and the locking bearings fell right out.Good design: It should be virtually impossible for the ball to pop off thanks to the clever groove pattern. The ball itself would have to break before it came off the post.The bad:Tight fit: Well, this isn't inherently a "bad" thing, really. There is little or no slop between the ball and the post. Good for stability, yes, but I could see it binding a little in a cold environment. Keep your spray lube handy and you should be good.The ugly:Nothing ugly: This set looks and works sharp.Other thoughts:Remember to take the ball off when not towing. It may be impossible for the ball to come off with a trailer locked on, but nothing stops it from hopping off down a bumpy road, or into a thief's pocket in a parking lot.

I had my doubts that this would work as advertised, but it really does - don't need to carry multiple hitches anymore. Solid, heavy duty design.

This is a great product idea and does save a lot of time as we have three different trailers with three different required ball sizes. However, make sure you lube both the inside and outside of the ball or it will friction fit onto the stud and it will be VERY difficult to remove/change. Due to the required grease, you need a good pair of gloves to grip and rotate the ball to remove it.

I like the versatility of being able to change hitch ball size so quickly.

This is a great kit to have if you tow with different trailers. Installs easily and the balls change out very easy.

Despite what you would think, you can totally leave a ball on when not towing, and it won't come loose. Even if it did, it wouldn't come up and off, it would actually lower itself on the shank and wouldn't easily be popped off due to the clever design.
