aka The Wedge No Rattle Hitch Stabilizer

I got this to take up the slack between my car's receiver and my Kuat bike rack. It keeps it nice and solid, although I now get rattling from the rack hinge instead of the receiver. This is much cheaper and easier to fit than the other designs that clamp around the receiver insert.

I tried to use this item on my 1 1/4" receiver hitch and it was a complete fail. It seems like it should have worked in principle. But it was obvious within the first few seconds of the install that it was simply NOT going to fit the receiver, and even if it did the physics (lever arm, vector of force etc.) of the design are so poor that there is no hope that it could do the job at hand. I bought this U-Bolt style hitch tightener: http://www.amazon.com/gp/product/B0001CMUV4/ref=oh_o03_s00_i00_details and it works GREAT.

Item didn't work for me. There needs to be 1/16 or so space between hitches to work. I did not have that much space, and the bevel is not thin enough to get in between and exert any leverage. I can see how it would work OK if there was more space.

Product works exactly as advertised when used with a SARIS Thelma bike rack. No more swaying when going around corners. Very stable now. Added a lock washer to make sure vibration does not allow the nut to come loose. Made very well with sturdy materials.

I was hoping this would make a good stabilizer for a new bike rack, and I figured it was at least worth a few bucks to try. Boy, was I ever wrong.There are two main problems with this alleged stabilizer. Problem number one is that for it to have any hope of working, you have to have a hitch with such huge amounts of play that the hitch was likely made by actual monkeys on their very first day on the job. The fat-fronted steep wedge just doesn't fit in the minuscule gap left in even a bottom-of-the-line hitch set, and even if the tip *did* fit, the wedge is not long and thin like a wood shim -- it's short and thick like a 45-degree miter cut. The thinner the wedge, the more mechanical advantage, i.e. the more stable the stabilizer.Problem number two is that the bent metal bracket (i.e. the black part in the image) is about as strong as a stick of refrigerated butter (or so it seems when it bends the first use). It is not even remotely strong enough not to bend when you're trying to tighten the stabilizer to get the chunky leading edge of the wedge into the not-nearly-made-by-monkeys gap in the receiver.If they remade this with a machined block instead of the bent sheet steel, the bending problem would be resolved. If the wedge were far sharper (i.e. at a far shallower angle -- thinner, if you will) so it could fit in the gap and slide in while tightening the machined block, the intended function would actually be realistic. As it is made, however, it is designed for failure -- and fail it did on each and every hitch and rack I tried.

Used to cut down slopp on a massive vertical 6 bike rack. I’ve got it tighten down pretty hard with no issues. They accidentally sent 3 in the package. May not work for all applications, but it did for me.

I attached a Pro Hoists brand extra-large cargo carrier to the back of my truck. I use it to haul my power chair around, because I am unable to walk well. I attached it to a Curt brand Class IV hitch receiver which I had installed myself. The carrier wiggled side to side as well as up and down while I drove. I installed this Boone Wedge hitch stabilizer to stop/minimize the side to side motion. It worked like magic. I installed another piece of hardware to eliminate/minimize the up and down motion. Now it rides like it's part of the truck, even with the 300-lb. power chair on it. I am thrilled with how this small piece of hardware eliminated such a big problem!

I liked the price for "The Wedge", so even after reading many of the negative reviews; I decided to try it out for a bike rack on the back of my Jeep Wrangler. Well, I guess my Wrangler's receiver was super tight on the sides and a little sloppy on the top and bottom. When I tried to wedge "The Wedge", even pounding away could not get the blade between the rack and the Wranglers receiver. Now if the "The Wedge" could somehow come in from the top or bottom of the receiver, it might have done some good. So, I guess I've got to go along with those negative reviews I read and am returning this to Amazon. I suppose that if you really have a ton of all-around slop between your rack and the receiver, this might do some good. So, make sure that you really need to tighten up the sides before you buy this.
