Video Transcript for Curt X5 5th Wheel Base Rails Adapter Review

Today we're going to be reviewing the Curt X5 gooseneck to 5th wheel rails adapter plate, part number C16210. Here's what it looks like once it's installed. It's a nice black carbide finish that's going to protect against rust and corrosion to make it last a long time. This adapter plate is ready for 20,000 pounds of gross trailer weight, and 4,000 pounds of tongue weight. It's a simple pin and clip installation for the 5th wheel hitches that include multiple mounting points to accept either a 5th wheel with legs, or a 5th wheel with a roller. Another nice feature about this adapter is that you can use it with just about anyone's 5th wheel hitches that fit on rails. Where some of the plates require you to use their brand of hitch, just check the weight ratings and make sure they are the same or less.

A great reason to get a plate like this is because you can easily convert your goose neck hitch into a the wheel set up without having to drill any extra holes. Now that we've gone over some of the features, let's show you how to install it. To begin our installation, I'm going to remove our rubber dust cap. We already have the arm released, so we can slide out our ball and set it aside. Now, we'll take our adapter and slide it into the hole. Next you can release your lever and let your dual pins lock it into place. Now let's show you how easy it is to use.

You simply drop in your 5th wheel, install your pin and clips, put those in place. We are ready to go hook up our trailer and hit the road. Now, that's going to do it for a review of the Curt X5 gooseneck hitch to 5th wheel adapter plate, part number C16210.

I use this on a 3500 Silverado which come with an original spray on bed liner. This makes my fifth wheel adapter very hard to hook to the goose-neck hitch. I virtually have to undo the main bolts and then torque them again after the adapter is hitched. Upon my complaint, I was told to simply cut out the bed-liner???? Imagine!!!! Once mounted, the fifth wheel hook up work just fine. I am lucky to own a pneumatic impact gun though.... 568126

Love my Curt C615-632 under bed rail kit, and Curt C16210 5th Wheel adapter. This is easy to use, and I can maximize the use of my box when not towing. The installation is clean with a small 4" cap when not towing. I was so happy with the product, I have purchased another C615-632 for my new truck also 473564

Fits perfectly into curt goose neck hitch. My reese 5th wheel hitch fits on the rails perfect. I haul dirt bikes in my truck so being able to take the rails out is perfect..... nothing in the way of loading or unloading 99283


Comments

Will the Curt gooseneck to 5th wheel rails adapter work with a Pro Series Slider 5th wheel? That is, will the slots match up?

-- comment by: Mike - 05/11/2014

Yes. The tab slot spacing is pretty universal amongst most manufacturers including Curt and Pro Series. Your Pro Series slider will drop right in to the the Curt X-5 adapter.

Took a bit of work removing pieces of the truck bed liner to get it in place, but it has worked wonderfully since then! We are "full time" 5th wheelers this year, and the hitch and adapter has been great. 625363

The product itself is great! Easy install into the B&W and a quick wiggle or two and my Reese hitch dropped right in. Very sturdy. Shipping beat their expected delivery by 2 days. The exterior box was a bit beat up, but the adapter was fine. Not even a scuff on the finish. etrailer.com has done right by me in all four of my major item purchases. Definitely recommend to others!! 628649

Excellent product that solved my issue of needing both a gooseneck & fifth wheel hitch in the same truck. Drops right in & fits perfect even with a spray in bedliner. Just towed our 20,000 lb toy hauler with it this past weekend- it performed flawlessly. It actually felt no different than our other truck with the fifth wheel rails bolted in, plus it can be removed & you can be back to pulling a gooseneck in minutes. 494852

etrailer priced matched to best the competition. The hitch was delivered a day earlier in great shape and ready to use. Exactly what I needed! Great job! The Curt 16310 hitch allows me the flexibility of using a B&W gooseneck hitch to pull a stock trailer. I can then install the 16310 hitch, drop my 5th wheel hitch on top and go camping. Thanks to everyone at etailer Corporation 547937

Works well with 5th wheel hitch. I was hoping to be able to remove adapter fairly easily to access flat bed when not using 5th wheel hitch, but that's not happening. It's a very tight fit in my gooseneck receiver, so not able to remove adapter very well. I'm disappointed in that, but otherwise pleased with your product. Thank you. 554188

Works great, I had a Reese hitch left from my old 5th wheel and two pickups with the turnover ball in the bed. This is easy to install and solid when pulling. Just what I needed.

I think this is great very handy and easy to operate just drop it in and go. The one thing I found out when I first used mine was there is a only one way to put it in and pin it properly. I had to take it out and turn it 180 degrees and drop it in, then the pin went in all the way. It's a very tight fit and that's important to me. Great product! 475630

Review from a similar Curt X5 in Gooseneck and Fifth Wheel Adapters


I was so happy to discover this adapter. I had to have a gooseneck hitch and wanted it to be hidden. I was dreading the fifth wheel rails sticking up in the bed again (bed replacement). This does the trick. Only reason for 4 starts is that it is a bit tight with no bedliner. Not even a spray in. But, I guess the maker has to build to a certain spec and not everyone would have a bedliner... 438660

Review from a similar Curt X5 in Gooseneck and Fifth Wheel Adapters


Excellent product, well made and fits as it should on both sides. A device like this, to be worth making and selling, has to have certain assumptions as to fit and function. Curt has done a great job of giving the customer flexibility in fitting up. In my case the (turnover ball) pin went part way in and stuck tight. I thought that removing the rubber shims on the underside of the adapter would be too much downward movement, so, with 5th wheel hitch installed, I found some washboard road to drive on. Problem solved; pin works perfectly. By the way, I call this thing a "spider". After all it has 8 legs. 426799

I recently purchased a 2015 Denali HD to pull our Rockwood 5th wheel. This truck had the B & W goose neck already installed. Instead of removing the hitch from the previous truck, I decided to try the B & W with the Curt X5 5th Wheel adapter. After reading the reviews, I was anxious to see if it fit as some said it did and others not. I ordered it on Wednesday and received it the following Monday. It was so easy to install and fit perfectly. Thanks etrailer. 424867

  • How to Tell Difference Between Curt EZr and Double Lock Gooseneck Hitch
  • Easiest way to tell which gooseneck hitch you have is by looking at the safety cable loops. If they are about as wide as the gooseneck ball hole and are centered with the ball hole it's an EZr, if the safety chain loops are a smaller and offset then it's a double lock. Take a look at the pictures of the EZR part # C611-624 and the # C607-604 and compare your safety chain setup to both of these. Let me know which yours matches and we can go from there.

And X5 adapter # C16210 fits Curt Double Lock, Flip and Store gooseneck hitches such as # C60720. The biggest difference to note is the shank from the bottom of the adapter is a different length. The # C16210 has a shank that is 4.41 inches long and the # C16220 has a shank that is 4.66 inches long. So the difference in the length also means the hole...

  • Recommended 5th Wheel Hitch for 2002 Chevy 3500 with Gooseneck Hitch Installed
  • When you already have a gooseneck hitch in your 2002 Chevy 3500, you unfortunately won't be able to add base rails as they will interfere with the gooseneck hitch mounts. There are adapters for some gooseneck systems that allow you to use more standard hitch options. For instance we have the Companion 5th wheel hitch # BWRVK3500 if you have a B&W gooseneck hitch or the Curt X5 # 16310 for that same system. If you have the Curt Double Lock, there is the X5 adapter # C16210 or # C16220...

  • I do have a solution for you, however the B&W Companion 5th Wheel Trailer Hitches like the Sliding # BWRVK3400-5W are not compatible with the Curt Gooseneck Hitch installed on your 2015 Chevrolet Silverado 2500. As you noted, the B&W uses a square shank while Curt gooseneck balls use a round shank and there is no current shaft or adapter available to allow the use of the two systems together. I recommend using the Curt X5 5th Wheel Base Rails Adapter # C16210. This will work with Curt...

  • Will the CURT Gooseneck-to-5th-Wheel Hitch Adapter Work with a Bedliner on a 2011 Ford F-350
  • I spoke with my technical contact at CURT Mfg. and he said that they have had no complaints about using the CURT X-5 Gooseneck-to-5th-Wheel Hitch Adapter Plate, # C16210, along with the CURT Double Lock Gooseneck Hitch on the 2011 Ford F-350. He also stated that the hitch and adapter plate have built in tolerance so they will work with spray in bed liners. On trucks with plastic drop in bed liners, the bed liner must be trimmed for use of the X-5 adapter.

  • How to Tell the Difference Between the Curt Double Lock & EZr Gooseneck Hitch
  • If you could send me a picture of the gooseneck hitch you have installed in your 2017 GMC Sierra 2500 then I would be able to make a more educated guess but based on your description you have the Curt Double Lock Gooseneck Hitch part # C607-604 and the correct adapter would indeed be part # C16210. However, if the gooseneck hitch was installed at the dealer then you would have had the Curt EZr Gooseneck Hitch part # C611-624 and the correct adapter would be part # C16220. I have attached...

  • Compatibility of Curt Gooseneck Hitch with B&W Companion 5th Wheel Hitch
  • To install a fifth wheel hitch that would be compatible with your existing Curt gooseneck hitch, I'd recommend using Curt X-5 adapter, part # C16210. This adapter will lock into a Curt Double-Lock, Flip and Store gooseneck hitches (C-60 and C-600 series). The adapter provides bed rails for a fifth wheel hitch that uses industry standard bed rails like Reese, Curt, Draw-Tite, Valley or Husky. The Curt Q20, part # C16130 would be a good choice. The hitch has a 20,000 lb capacity and a...

  • Gooseneck Adapter For Sliding 5th Wheel Hitch
  • There is not a square shank adapter for the B-W Companion Sliding Hitch # BWRVK3400 for any other underbed gooseneck system. It is only compatible with the B&W gooseneck system. You may be able to use the Curt X5 5th Wheel Base Rails Adapter for Curt Double Lock Gooseneck Trailer Hitches - 20,000 lbs # C16210 although this is not a confirmed fit. If that adapter fits, you could use it along with any standard sliding hitch like the Curt Q20 5th Wheel Trailer Hitch w/ R20 Slider -...

  • Solution for Towing 5th Wheel Trailer with Curt Double Lock Gooseneck Hitch
  • I do have a solution for a more secure setup to tow a fifth-wheel trailer, however the B&W Companion # BWRVK3500 that you referenced is not compatible with your Curt Double Lock Gooseneck Hitch. The Companion is designed specifically for the square ball hole that the B&W Turnoverball Gooseneck Hitches provide and cannot be adapted to fit your Curt system. I instead recommend using the Curt X5 Base Rails Adapter # C16210. This is designed to fit your Curt Double Lock Gooseneck Hitch...

  • Installing Fifth Wheel Hardware Over Existing Gooseneck Plate on a 1997 Dodge Ram 2500 8 foot bed
  • According to my technical contact at Reese it is not recommended to have both a gooseneck and fifth wheel hitch installed at the same time and to have both useable. The reason for this is exactly as you have indicated that the mounting hardware that secures both of the hitches to the truck uses the exact location on the truck frame. If you were to drill through the existing hardware in order to mount the fifth wheel hitch it could compromise the integrity of the gooseneck hitch. These hitches...

  • Under Bed 5th Wheel Trailer Hitch Installation Kit for a 2015 GMC Sierra 1500 Short Bed
  • Reese does not offer an under bed 5th wheel installation kit for your 2015 GMC Sierra 1500. The least expensive under bed and hitch option is going to be from Demco using installation kit # DM8551008 and HiJacker hitch # DM8550022 for a short bed. Another option is to use Curt gooseneck hitch # C615-632 and X5 adapter # C16210. The X5 adapter fits in the gooseneck ball hole for this gooseneck hitch and provides standard rails to mount a hitch. If you do not already have a hitch you can...

  • Gooseneck to Fifth Wheel Hitch Adapters Compatible with Round Shank Curt Receivers
  • We have a solution that will give you the ability to use a fifth wheel adapter with the Curt gooseneck hitch you have in your truck, but there is nothing that will allow your B&W Companion hitch to fit into the round ball hole on your gooseneck hitch. We do carry the Curt X-5 Hitch Adapter Plate, part # C16210, that is designed to work with your Curt hitch. This adapter comes with the round shank needed for the gooseneck hitch you have installed in your vehicle. Once this adapter I installed,...

  • Gooseneck to 5th Wheel Adapter Needed for a 2016 GMC Sierra Denali 3500 with Curt Gooseneck Hitch
  • From the pictures that you sent in it looks like you either have the Curt Double Lock # C607-604 or the Curt EZr Double Lock # C611-624 installed on your 2016 GMC Sierra Denali 3500. If you have the Double Lock # C607-604 then you can use the X5 Adapter # C16210, but if you have the EZr Double Lock # C611-624 you will want to use the X5 Adapter # C16220 instead. Either one of these options will provide you with a standard base plate kit for you to use a 5th wheel hitch with standard...

  • Fifth Wheel Hitch Adapter Compatible w/ Reese Hide-A-Goose Under Bed Gooseneck Hitch
  • My Curt representative tells me that they don't offer an X5 adapter model that would be compatible with your Draw-Tite # 9465-54 under bed gooseneck hitch. If you have a long bed truck, the Draw-Tite Hi-Rise Gooseneck to 5th wheel hitch adapter, part # 9480 would work well for you. Another option would be the Reese Goosebox, which would replace the existing 5th wheel's pin box. The Goosebox will allow the 5th wheel to connect directly to the gooseneck ball, without an adapter needed....

  • Can a 2016 Ram 1500 with Air Suspension Package Tow a 5th Wheel Trailer
  • There is a way to tow a 5th wheel trailer with a 2016 Ram 1500 that has the air suspension package. To do it you will need to start with a gooseneck hitch, # C607-658. Then you can use the X5 adapter # C16210 and place a 5th wheel hitch on it. I recommend the Curt A16, # C16120 for a long bed or # C16521 for a short bed. Manufacturers have not yet figured out a way to install 5th wheel brackets on a Ram that has the air suspension package. It has been out for awhile now but still no...

  • Towing a 5th Wheel Trailer with a Factory Gooseneck Hitch in a 2016 Chevy Silverado 2500
  • The Curt X5 adapter # C16210 is designed to fit Curt aftermarket Double Lock gooseneck trailer hitches. I know Curt makes the OEM setup for GM but the adapter is not for that setup. There are other adapters that you could use though. First, if you don't have the factory ball you can add one using # C60692. Then you could use the Andersen Ranch Hitch # AM3100 which clamps around any 2-5/16 inch gooseneck ball. This is the only adapter that offers true offset (moves the pivot point of...

  • Available Gooseneck to 5th Wheel Hitch Adapters for 2008 Ford F-350 Short Bed
  • The gooseneck-to-5th wheel adapter you need depends on which gooseneck hitch setup you have installed in your 2008 Ford F-350 short bed. All gooseneck hitch fits for your truck are shown on the linked page. Some use a round ball hole while others use a square hole. For example, if you happen to have Curt gooseneck hitch # C60720 or # C640-644, both of which have a round hole for the gooseneck ball, you can use the X5 Adapter # C16210 that provides the equivalent of industry-standard...
