CZC AUTOHitch Clamp Anti-Rattle Stabilizer Heavy Duty Cross Clamp 2 1/2 Inch for Hitches On Trailers of Trucks SUV Vans RV, Hitch Tightener Clamp for Hitch Tray Cargo Carrier Bike Rack Ball Mount

My husband was excited to get it. Have not used it yet.

Great quality for price. They fit up to 3" wide and coated for weather resistance.

This is our second anti rattle clamp. The first developed cracks in the corners of the U bolt after several thousand miles of towing. No big deal so we purchased a new clamp. This one had a vinyl coated U bolt which we removed the coating because it just made the clamp loose from the vinyl compressing. Also noted is that the bolt seems to get loose quickly from stretching? We use it with a WDH and is mounted so the clamp provides the proper upward pressure for this hitch type. Not sure how long this one will last.

It's very weird and hard to put this on a ram 3500.

Surprisingly this works great for quitting down a rattling receiver hitch.

It does not work on a factory class V ram 2500 hitch, not enough room to install. It looks very sturdy

Grabs tight and is very sturdy

I liked it was easy to install and performed as expected to prevent the “bouncing” of a loose rack to hitch connection. I needed to reduce down a couple sizes and this took the stress off the rack equipment. Plus it allowed me to put the bikes on the back of truck instead of the bed which always took two people plus I have a 5th wheel hitch to work around.

Used it the first time this weekend and my trailer hitch did not move at all.

Perfect for GM 2-1/2 hitch. Works with 2-1/2 to 2 inch hitch reducer. Deducting one star for thick vinyl coating, not needed and will just split first time the clamp is tightened.

Good quality product. Definitely stops the annoying clunk of the hitch while pulling trailer when installed correctly. And the manufacturer DOES NOT have correct instructions. The manufacturer shows to pull the hitch to the top of the receiver vs pulling it down. Compare their instructions to my attached pictures. IT MUST BE PULLED DOWN!!!! When it’s pulled up any weight on the hitch puts pressure onto the clamp and it stretches and bends the clamp which makes it comes loose! When it’s pulled down any weight on the hitch puts the weight onto the receiver instead of the clamp and the clamp does not come loose.

Bought this and used it for a year. By the end of that, the U bracket was distorted completely out of shape, as it's clearly made with cheap steel. As well, even with a locking washer, the nuts just loosed off, requiring a constant tightening. Ended up having to use blue loc-tite every time I used this. At the end of the rv travelling year, I threw it away and got a better quality one made with better metals. Sure, I paid more, but what a waste of money this one was.
