The Curt Anti-Rattle hitch clamp has worked very well once installed. I could not give five stars because it is quite sensitive to get adjusted to work properly and is not convenient to remove regularly when not needing a trailer hitch on my truck. I will be removing the clamp after I have no need for the snowmobile trailer in spring. It has not been needed for the weight distribution hitch on the travel trailer. 2021 Chevy Silverado 2500HD.

The device worked as promised but I am quite disappointed with how quickly it started to rust which then made for difficult adjustment or removal to change hitches for my various trailers.

This will not work on a 2022 Ram 2500. The Receiver hitch is tucked up tight against the bumper and recessed. No way this can work.

Since the hitch receiver is recessed then the only anti rattle device that I can recommend would be an anti-rattle lock part # SHP2040-XL
XL Anti-Rattle Trailer Hitch Receiver Lock for 2-1/2" Hitches - 3-1/2" Span
. This would work with hitch accessories that have a hollow shank versus a solid shank.
-- Etrailer Expert Rebecca N - 07/13/2023


I bought this with semi-low expectations based off other reviews, but I am surprised so far with how tight of a fit it is, and has taken away the movement in the hitch. I haven't towed a heavy load yet, but so far seems to be holding up great. Customer service was top notch, I ordered this ans it got lost in transit, so I reached out and the quick sent me another right away! Definitely worth the money for a quick fix.


This product may work well but it did not fit on my 2019 RAM 2500 due to the hitch receiver design (bumper in the way) on the RAM so I can not recommend it for that vehicle.


Works great.


Very disappointed with this product. It's supposedly made for 2 1/2" receiver hitches and it won't hold up to a heavy duty truck. I have a tow bar rated for 1,400 tongue weight and it broke on the first use. I complained to Curt and attempted a refund and all they would do was replace it, and that took 8 months. So I compliment them for standing behind it and replacing it, but that does me no good since it's under rated for my use. I would avoid this unless your tow equipment is very light, which is unrealistic for a 2 1/2" tow bar.

I do have an alternate more robust anti rattle device part # BX88225 to offer. Please take a look at the video link below.

This item doesn't fit a Ram 2022. You all are charging me return postage! You should tell buyers that this item doesn't fit some hitches.

This fits a 2.5 inch hitch with a collar.

Not super thrilled- after checking it going down the highway it had shifted and I was still getting jerking motion. Did not have a wrench so I had to deal with the bouncing. Super tight fit trying to screw the nuts onto the U-bolt. 3500 Ram Dually 2018


Great experience!


Item crumpled / broke under towing stresses. The crossbar is a “pot metal” material - not a good selection.


Tight fit on my ram 3500 but it installed with no issues


2020 Ram 2500 21/2” receiver. Device. doesn’t fit. Not enough clearance between bumper and receiver to slide U BOLT into position I will return to etrailer. Curt or etrailer should have known this, and stated so, in the product details before selling. Put me down as a frequent, but unsatisfied etrailer customer.

I will have Customer Service reach out to you.
-- Etrailer Expert Thomas M - 01/08/2022


Real fast shipping, and a competitive price. Easy to follow directions and simple installation. This is a great product.


Exactly what I needed. Easy to install and stopped the rattle perfectly.


Feels like cheap pot aluminum. Difficult to get tight on hitch. Not easily taken on and off.

You mentioned that it was difficult to tighten on the hitch and to remove. I wanted to see if you could send a picture of it on the hitch?
-- Etrailer Expert Jenny N - 03/23/2022
Unfortunately, I threw it away months ago. After reading some of the reviews, it see,s to be a common problem for the Dodge Rams.

I recommend taking a look at the Blue Ox Immobilizer part # BX88312
Blue Ox Hitch Receiver Immobilizer III for 2-1/2" Hitch with 2" Adapter
as an alternative.
-- Etrailer Expert Jenny N - 03/23/2022


Keeps my ebike hitch from rattling and rocking.


I’m very pleased. Works like advertised.


looks like it would do the job, but it absolutely will NOT work on my 2022 ram ...
sending it back


I was installing this on a 9017 ford f250 With a 8 inch ball mount. The way the handle works I could not get the clamp to tighten enough to stop the rattle. I could only turn the handle 1/2 turns on the flat side of the handle. The only way I could make is work is to remove the handle and install using a nut and lock washer on the handle side.


did not work comes loose after a few miles would not buy again


Does not fit on my 2021 F350. What a piece of junk.

You mentioned that it did not fit on your 2021 Ford F350 and I have a question that I wanted to ask. Does your hitch have a ring or collar?
-- Etrailer Expert Jenny N - 07/07/2022


This clamp would not work on my 2012 Nissan Pathfinder with factory hitch.


good product


Had to over tighten so much needed to use hammer to close and of course beat it to death and it broke


Worked great to harden up the hitch.

  • Recommended Device to Remove the Excessive Play and Rattle Between 2-1/2" Receiver And Hitch
    I do have a solution to help you get rid of the excessive play that you have with your current Equal-i-zer shank as you are always going to have play in any receiver that you use. Excess play in the parts is required as the steel can expand and contract at different intervals and if corrosion develops inside the receiver you will still be able to remove the hitch. The Curt Anti-Rattle Hitch Clamp # C87UR is a no tool clamp that I recommend using on your 2015 Chevrolet Silverado 2500HD....

  • Recommended Anti Rattle Device for a 2 1/2" Hitch with a 2" Reducer
    The best option for your set up will be the Blue Ox Immobilizer III # BX88312. This is specifically for a 2 1/2 inch hitch being used in unison with a 2 inch reducer.

  • Recommended Anti-Rattle Device for a 2 1/2 Inch Hitch
    The Curt Anti-Rattle Hitch Clamp # C87UR is a good option, but I personally an not a total fan of the clamping handle piece. If the point where the handle should be snapped down is 1/4 turn too much, you would either have to back it off that 1/4 turn, or try to over tighten it to get the handle in the correct spot. It does, however, have a very nice feature. This is a tool free install and removal process. The nut can get a little tight while in use, but generally, once the snap handle...

  • Recommended Hitch Anti-Rattle For A 2021 Ram 3500
    Assuming your 2021 Ram 3500 has the OEM 2-1/2" receiver, I recommend the Roadmaster Quiet Hitch # RM-062. This is a u-bolt style anti-rattle device, which is known to be very effective for reducing play in the hitch. The u bolt is tightened manually so you will need to carry a wrench with you, but this will allow you to put plenty of tension on the hitch. Please note that the hitch receiver must have a ring or collar around it for Quiet Hitch to attach to. If there is very little clearance...

  • Can The Reese RP45018 Extension Be Used To Flat Tow A Jeep Wrangler Behind A 2021 Ford F-350?
    As you Jeep Wrangler weighs 4,200 pounds and you will be using the Reese Titan Hitch Box Extension # RP45018 at the 41" length, there will be no issues using it on your 2021 Ford F-350. You are getting pretty close to the 5,000 pound max capacity though, so I do not recommend adding any extra weight to the Jeep when you are towing it. With that said, I do recommend a couple add on parts to go with this. The Curt # C87UR (for 2-1/2" hitch) and # C27UR (for 2" hitch) anti rattle devices...

  • Long WDS Shank For 2-1/2 x 2-1/2 Trailer Hitch
    We do have a version of the Equal-i-zer Weight Dist Shank # EQ90-02-4600 you mention, however it is 6" shorter. The Equal-i-zer Weight Dist Shank # EQ90-02-4800 offers the same rise and drop as # EQ90-02-4600, has a maximum tognue weight rating of 1,600-lbs, a maximum towing capacity of 16,000-lbs, and will fit into a 2-1/2" x 2-1/2" trailer hitch receiver. Alternatively, you could use a hitch reducer sleeve # C45405 which would slip into your receiver and allow you to use # EQ90-02-4600...

  • Can The Thule EasyFold XT Bike Rack Be Used On a Class V, 2-1/2 Receiver?
    The Thule EasyFold XT Bike Rack # TH903202 will only fit a 1-1/4" or 2" receiver directly. You can use a Brophy Hitch Reducer and Extender # HR26 that will allow for the stinger to fit on your vehicle. The stinger that holds the rack into the receiver will not work on a 2-1/2" or 3" receiver. The Curt Anti-Rattle Hitch Clamp # C87UR will take the rattle out of the extender and allow for the entire bike rack to be solid as it has its own built in anti-rattle for the 2" or 1-1/4" receivers....

  • Class IV Weight Distribution Hitch With Sway for 2019 Venture SportTrek 38 Travel Trailer
    First you will want to confirm what your tongue weight is that you will be towing with. You can do this with a tongue weight scale like the etrailer scale # e99044. This will ensure that you have a weight and sway distribution hitch that is correct for your 2019 Venture SportTrek travel trailer. This device will plug into the OBD II port on your 2017 Ford F-250 and will tell you the tongue weight of your camper as well as help you setup the new weight and sway hitch. For tongue weights...
