Video Transcript for Curt Fifth Wheel Rail Sound Dampeners Review

Hey everyone, how's it going Today, we're going to be going over and showing you how to install the Fifth Wheel Rail Sound Dampeners. So, this is a rather simple product. It's not necessarily something that's going to be required for your setup. But if you towed many trailers before, had a couple of different fifth wheel hitches, you're probably aware of that some of them have some movement within the base rails of our truck. Now, there's a lot of different variances that have this. It comes down to which fifth wheel rails we have, which fifth wheel hitch we have, the tolerance, tolerance stacking of the two or improper installation of our fifth wheel rails.

There's a lot of different reasons and factors that can come into play when we have movement of the fifth wheel hitch in our rails. Now that's certainly not something that we want to hear each time we get in, couple our trailer, we come to a stop at a stoplight hearing that fifth wheel hitch rock back and forth on our rails. Therefore, installing the sound dampeners here we're going to help improve that overall ride and cut down on the sound of our hitch moving inside the rails. So these are what our dampeners look like. It's a pretty simple design.

We have four of them, one for each attachment point on our fifth wheel legs. These are made of rubber, so they're nice and durable, but they also have some give to them, which is what allows them to have that dampening property. So they are rectangular shape. And we also have that rectangular cutout here, which is sort of going to mimic the shape of the attachment to our fifth wheel rails. So basically how these dampeners work is, this is going to be a rubber pad that installs between the bottom of the fifth wheel hitch and the top of the rail.

And it's going to provide sort of a cushion or a barrier between the two so we don't have that metal on metal contact. Now in order to install these, it's very easy. You're going to want to do one side at a time. We're going to pull out the two front pins. So we have one here and then we have one we need to pull out over here.

Now, once we have the front two pins out, we're going to lift up on our fifth wheel hitch assembly here. You are going to line up the rectangular slot there with our dampener. You may need to readjust the dampener when we have the fifth wheel hitch down. But that's pretty much how they're going to install and may or may not sit flat depending on how well they are aligned. You can sort of play with them a little bit to get them perfectly centered on that rectangular hole. But once we have one side in, we'll go ahead and repeat that same process on the other side. And then we'll just simply reinstall our pins. Now with both of our rear pins out, you can just come back here pretty much just do the same thing. And that's going to do it today for our look and installation of the fifth wheel rail sound dampeners..

Fifth Wheel Rail Sound Dampeners - 16900

Average Customer Rating:  4.5 out of 5 stars   (143 Customer Reviews)


Fast order processing and fast shipment. Product works good but would be better if the material was more impact resistant.



They tear too easily. They need to be made of a harder rubber or neopreneplastice material that will hold up better. Something similar to a 5th wheel lube plate but all the dimensions and thickness same as the damping pads.

@Roger That's a nice idea. We'll pass that along to Curt!


Great service and fast shipping. I have a home office and was working on a Sunday afternoon. I received a call from George to inform me of the status of my order. I thought I was the only one working on Sunday lol. I was sure wrong. I am very impressed with their customer service. I will browse their site and will buy from them.

John W.


I still love it. It is working great. Your service was as great as the product.


It works great.



Easy to change hitch types. Works great


Worked as expected. I like the flexibility being able to use it on the Ford or Chevy.


Box was destroyed and missing parts, called and notified E Trailer told them I needed the missing parts by Friday so I could pull my 5th wheel. Operator acting as though she couldn’t care less and told me she would just wait on an email


Although they do the job in removing slack and dampening any sound from the slack, they simply do not last. The rubber starts to tear very quickly. My current ones Tire after just 3 camping trips. I typically go through st least a couple sets of these per camping season.

I am sorry to hear that you are needing to replace these so soon. I see that this item has a one year warranty. I have sent your information over to our customer service department for them to contact you about a possible warranty.


These neoprene "spacers" are each 1/10th of an inch thick, are very flexible, and are designed to keep the Curt hitch quiet and to stop the Curt slider rails from contacting the bed. Instructions refer to these as "spacers" and that they may not work with all mounting applications.
I bought these for my Reese/ProSeries hitch to keep it quiet and they are a snug fit, but they fit ! Hopefully they will hold up to my 17K lb 5th wheel, but if not they are cheap enough to replace, depending on how much life I get out of them in the torturing southwest desert sun.


I was trying too eliminate the clanking of my hitch, so I ordered these Curt rubber spacers, and after waiting for the order, they don't work. The problem is that when they are installed they raise the base and you are unable too slide the pin in too secure the hitch too the rails. Waste of my money since I purchased 2 set's.


these actually do work as they do dampen the sound by cushioning between the rails and the 5th wheel hitch. I am satisfied with this purchase.


I bought these for a reese hitch, they do not actually fit the mount for my 5th wheel, i actually installed 2 pads on each corner and it seems to have worked.
I had ordered 2 sets so I had them on hand. we will see how this goes once we start traveling soon


Product is OK, does not last long, poor design of hitch mounting. If rubber had metal backing on one side it would last longer.

Douglas M.


Hitch is good. The noise suppression rubbers need designed better as I have previous stated. Made my own metal pieces to go with the rubbers and they last a lot longer.


I adapted these with a piece of sheet metal to fit under a set of Reese legs that were shaped like a channel.

They have virtually eliminated the clanging noise of the hitch legs banging around in the rails.

We are VERY pleased with them!


Was a tad shocked when the item arrived due to the size as I was expecting something thicker after all the reviews about trouble installing pins after installation of rubber pads, that aside I am happy with it as I don't hear the fifth wheel while going down the road but as for longevity we will have to wait and see. If your 5th wheel clanks going down the road you need this product.


Anderson hitch has made things very easy to hook up and go as we do multiple times a year. The locking cable froze during extreme cold one time and had to take it off and warm it up for a few minutes, but then worked fine.


As already mentioned they do initially make it hard to put hitch pins in. I had to use a rubber mallet. I think once they get bedded in it will be easy though. Does isolate hitch from rails nicely. It's a thin but dense rubber and at least when initially installed has taken whatever slight play the hitch had in the rails right out.


Worked as advertized. Adding these took out the little bit of wobble I had in fifth wheel hitch where it mounted to the rails. Easy to install. Just put them over the tab on the hitch that goes into the rail.


This item is orignal part I needed to take metal to metal noise and slack from my curt 5th wheel rails. Delivery was fast. I will definitely use again


Installed these on my new Curt A25 hitch, hoping they isolate and reduce some metal to metal "clanking" between the hitch and the rails.


I actually could not get my hitch pins to go into place with these washers/spacers in place. To be honest, I did not spend a lot of time trying to push down on hitch to make them work, because I was in a hurry.


Shipping was fast and these will help with noise and wear on 5th wheel mounting rails. Tracking of shipping was so easy .


These little rubber snubbers are great. They quiet the noise from the play in the hitch when changing direction, forward, reverse, of starting from a stop. They also keep the rails from getting chipped and rusting!


Used with my curt 5th wheel to gooseneck plate. Highly recommend this. Stops rattles and makes the fit super tight.


Good service is the reason why I buy from every time.

Dennis R.


The Curt Hitch is working out really well.I bought the dampers for the rails they do the job.


Cannot believe we ordered this just last wed. And it was delivered this Monday morning. So excited to get it on the truck and see how it pulls the gooseneck trailer. Will send pictures when we get it in. Thank you for such a fast delivery. And no damage to box. Kathy want to say thank you. You answered everything. You were a big help. Lana


So far, so good. Installed them yesterday. They certainly tightened up the connection between my rails and the hitch. I have not towed my camper yet but they cannot help but reduce the rattling at the hitch. I hope they hold up.

  • Help Reducing Play Between 5TH Wheel Hitch and Rails Allowing Hitch To Rock And No Longer Sit Flat
    Something that may help you is by placing some spacers or Dampeners # 16900 between the hitch and the rails. This will reduce the amount of vertical play your Curt 18K 5th wheel hitch has and prevent it from rocking around inside your rails.

  • Excessive Noise When Using Curt A16 Fifth Wheel Hitch On 2015 Chevrolet Silverado 2500
    There is not an actual adjustment that can be made on the A16, part # C16621. The hitch has a pivoting head that is cushioned so a bit of movement may be present when towing. If you can find the source of the noise it can help. It may be caused by the slider or by the jaws on the king pin, or the large pin that is in the middle of the hitch. You may want to check out the Curt Fifth Wheel Rail Sound Dampeners, part # 16900. These are neoprene pads that fit between the hitch and the rails...

  • Troubleshooting Curt Fifth Wheel Hitch Where the Sound Dampeners fit Very Tight
    You will want to put the rubber spacers on the mounting tabs of the Curt Hitch part # C16541 before you drop the hitch into the rails that are installed in your bed. The first few times you install the hitch the cushions will make the pin pretty tight, but after a few times they will install a bit easier. Some people like to replace these every year, for that you would want part # 16900.

  • Troubleshooting Play Between Curt Hitch Legs and Curt Bed Rails
    This is normal behavior for a 5th wheel trailer hitch. Considering the amount of weight involved and all of the steel components there is going to be some play. In fact, where the hitch fits in the rails has to have some play. If it was tight you would not be able to easily get the hitch in and out of the rails. You can try using dampeners like part # 16900, to fit between the hitch and rails. They are made to stop rattle and might be all you need.

  • 5th Wheel Slider Hitch Makes Excessive Noise when in the Towing Position on a 2014 Ram 2500
    I am not sure which 5th wheel trailer hitch you have. It sounds like a Curt hitch with a round tube slider. Sliders are going to be noisy since there are more places on them for movement compared to a fixed hitch. In addition, on 5th wheel hitches that have a head that pivots on a center bolt, there is usually some back and forth movement at the head hitch is normal. There are supposed to be rubber O-rings at the ends of the round tubes the hitch slides on, front and back, so 4 total....

  • Cant Insert Pins to Secure 5th Wheel Hitch in Adapter C16023 if Using Rail Sound Dampeners 16900
    Fifth Wheel Rail Sound Dampeners # 16900 were originally designed to fit on industry standard above the bed rails. The adapter you mentioned, # C16023, has the slots in it to emulate industry standard rails so if the dampeners were compressed enough (with enough weight pushing down on them) then that should allow you to use the regular pins. You definitely want to use the regular pins and nothing smaller because a smaller pin would not carry the same rating. If you just cannot get the...

  • Reducing Noise from B&W Patriot Slider 5th Wheel Hitch when Not Towing a Trailer
    Fifth wheel trailer hitches, especially sliders such as # BWRVK3270, can make some noise when there is no trailer connected just like you said. Since a slider has extra components and other moving parts there are a lot of places for potential movement. To reduce the noise between the hitch and the rails it mounts to you can use sound dampeners # 16900. They will go between the hitch and the rails and will reduce the sound at those points. Movement in the slider parts or other hitch parts...

  • Can the Curt Above-Bed Gooseneck Trailer Hitch Part # 16055 Install Both Ways
    Yes, the Curt Above-Bed Gooseneck Trailer Hitch for Fifth Wheel Rails part # 16055 can be installed where the offset is closest to the cab or where the offset is closest to the tailgate. In order to reduce rattling, I strongly recommend using the Fifth Wheel Rail Sound Dampeners part # 16900 between the gooseneck hitch and base rails. You may also want to consider using the Curt Safety-Chain Loops for Gooseneck Hitches on 5th Wheel Rails part # C16000 as some states require that safety...

Where the hitch fits in the rails has to have some play. If it was tight you would not be able to easily get the hitch in and out of the rails.

  • What is the Weight Of The Curt Spyder Gooseneck Trailer Hitch for Fifth Wheel Rails?
    The 30K Curt Spyder Gooseneck Trailer Hitch for Fifth Wheel Rails # C35HR weighs 76.2lbs. If you feel this is too heavy we do have their 25K Spyder # 16085 which only weighs 50lbs. I do recommend using the Fifth Wheel Rail Sound Dampeners # 16900 with either hitch to help reduce the amount of noise the hitch makes in the rails, both with a trailer connected and without.

    Yes, the Curt Custom Fifth Wheel Installation Kit # C79BR will allow you to install the Pull Rite 5th wheel hitch in your 2017 Ford F-250. The Pull Rite fits inside these Industry Standard Rails. You will want to add the Fifth Wheel Rail Sound Dampeners # 16900 to help quiet the noise. Be sure to install the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # 41157 so you will be able to connect the 7-way for your 5th wheel inside your bed.

  • Fifth Wheel Hitch Experiencing Back and Forth Movement While Towing
    The 1/2" pin is pretty standard with fifth wheel setups because they have to fit through the rails in the bed. All of the fifth wheel pins we carry are 1/2" options. If you are just concerned about rattle I recommend to use Curt Fifth Wheel Sound Dampeners part # 16900. They install between the hitch and mounting rails to eliminate some of the rattle while you are driving. These will work with any industry standard fifth wheel rail in the bed. You may be experiencing chucking or jarring...

  • Troubleshooting A Clunking Noise Between A Fifth Wheel Hitch And Base Rails While Towing
    It's totally normal for a bit of movement between any fifth wheel hitch and the base rails. The feet on the hitch are typically a bit smaller than the slots they slide into for mounting otherwise you'd have a hard time getting your hitch in or out of the base rails. This does cause a bit of noise and would allow you to pull up on the hitch slightly. If you're getting a lot of movement then it leads me to believe that either an incorrect sized pin is being used to mount to hitch into the...

  • Will The B&W Patriot 5TH Wheel Fit On Demco Adapter Rail For a 2024 Ram 2500?
    Yes, the B&W Patriot 5th Wheel Trailer Hitch # BWRVK3255 will attach directly to the Demco 5th Wheel Rail Adapter # DM6099. Do understand the rail adapter will add 1-3/8" of height to the hitch giving you a height range of 17-3/8" to 20-3/8" from your truck bed mounting points on your 2024 Ram 2500. Do remember to use a Lube Plate # RP83002 on your 5th wheel king pin to help reduce noise and increase the life of your hitch head. The Rail Sound Dampeners # 16900 can also be used to reduce...

  • Curt 3" Offset Above-Bed Gooseneck Compatibility With Curt 5TH Wheel Rails On 2014 Ford F-350
    Yes, the Curt Above-Bed Gooseneck Trailer Hitch # 16055 will fit the Curt Custom 5th Wheel Installation Kit # C16424-204 that you installed in your 2014 Ford F-350. You will not have to make any alterations. The Fifth Wheel Rail Sound Dampeners # 16900 will cut down on the rattle from the plate when you are not hauling. And I do find the Curt Safety-Chain Loops # C16000 are much easier to use for securing the safety chains than the small holes in the gooseneck plate.

  • Loose Connection Between Curt A20 Hitch and Curt Base Rails
    Since you mentioned the cotter pins which are used to secure the feet inside the rails, that makes me that you are referring to the connection point between the rail and foot on one of the four corners of the Curt A20 5th Wheel Trailer Hitch part # C16140. If that is the case then you will want to inspect the hole on the foot, the hole inside the rail, and the pin that connects these together. If these holes have become misshapen then this could very well cause the loose connection that...

  • Curt 5th Wheel Rails to Offset Gooseneck Ball Adapter With Reese Goose Box
    Yes, the Curt Above-Bed Gooseneck Trailer Hitch # 16055 can be used with a Reese Goose Box # RP85FR. Be aware that the gooseneck ball will sit a couple inches higher that a typical bed mounted gooseneck ball. I recommend using a set of Fifth Wheel Rail Sound Dampeners # 16900 as well as Curt Safety-Chain Loops # C16000 with the hitch adapter. This will help quiet a bit of the noise and give you an easy location to connect your safety chains.
