CURT 42225 1-7/8, 2 and 2-5/16-Inch Chrome Steel Switch Ball Set, Up to 8,000 lbs. GTW

This thing is amazing! Just a quick twist and you can change the ball size.

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.

If the ball is not under the weight of a trailer, it falls out of the groove. If I am not mistaken, this could lead to the ball coming off at an in opportune time.

But shows rust very quickly

Very nice to have interchangeable

Very awesome,so easy to make chang or ball size, very simple and quick

all item was received as described no missing item in side the box, missing item was inside the box

Simply ingenious! One shank, three balls - no more switching around between the 2" and 2-5/16" balls. The best part is, no tools, just greasy fingers :-)

Very slick set up , makes changing out the balls easy. I wish I would have had this years ago , a must buy if you have different trailers

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.

Arrived on time. Great price

Great for all different trailer heights and ball sizes

tres utile pour les gens comme moi qui a plusieurs equipement avec plusieurs grosseur d attelage
