CZC AUTO Hitch Tightener 304 Stainless Steel Anti-Rattle Stabilizer for 1.25 2 Inch Hitch Rust-Free Lock Down Hitch Stabilizer for Hitch Tray Cargo Carrier Bike Rack Trailer Ball Mount 2 Pack

If you’re looking for something to keep your inserts from rattling/ making noise every time you’re pulling your trailer, this is something you should consider. I purchased two of these one for myself and one for my son in law. Both of us are pleased with the result/ quality.

Very easy to install. Used some never sieze on the threads to help not to gawl the threads. Makes my hitch stable and not move.

Editing to respond to those complaining about seized threads! DO NOT OVER-TIGHTEN. This is stainless steel so, yes it's softer than normal steel. This item is made to be rust-proof so it's a trade-off you decide on. Only lighten until the split washers are fully compressed. <end of edit> Easy to install and very sturdy for a cargo tray (hitch hualer). This item comes with standard stainless nuts. While the split washers should prevent the nuts from backing off, I'm paranoid so I replaced them with stainless nuts with nylon inserts. It might not be necessary but this would be my only recommendation to the manufacturer. All-in-all, I'm very pleased with this product.

Oh my, what a noise / ride difference. This thing locked my receiver down and improved my towing ride by at least 90% !!

I have finally had a chance to install this Hitch Tightener on to my hitch bumper that I also purchased from Amazon, so far I am not hearing anymore noises and the hitch bumper is so stable I can literally push the bumper and the car shift without any shifting of the metal against each other.

Another reviewer warned that the bolt stripped out after one use. I didn't even get that far. I installed this product to test it out and it went on fine and seemed to firm up my trailer. I then tried to remove it and found one of the nuts very difficult to loosen. Afterward - as you can see from my photo - I discovered the bolt threads completely mangled. I can't think of any reason why this would happen. The nuts went on smooth as can be. I tightened it with only an 8" ratchet - not very much torque and definitely not too tight. I think they must be using some *very* soft "steel" here. Who knows... setting up a return now. If you plan to buy one of these I suggest searching for grade 8 steel and nothing else.

Good quality and fits perfectly. Having one made of stainless eliminates the rusting issue.

I installed this bracket to stop the vibration on my bike carrier which it did. After 3 weeks I tried to remove it and one of the nuts was frozen/stripped threads on the U-bolt. I eventually broke one side of the U-bolt trying to get it off and it isn't usable until I can find a replacement U-bolt and nuts.
