Heavy and doesn't fit flat on my truck bed, had to add some heavy duro rubber shims between this and the bed floor. I paired this with the C611-624 gooseneck hitch. 628760

Works great. The fifth wheel adapter has been used to tow my 19,000 gvw 5th wheel trailer from Wisconsin to Texas back and forth for 2 years.

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

The only problem i have had Is that I noticed the bracket dented my truck bed. ie: front to back pressure allows the rocking of the bracket, therefore putting a dent in the bed of the truck. 570068

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

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


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

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

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

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

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


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

Do you have a question about this Gooseneck and Fifth Wheel Adapter?


  • 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. The part # C16210 is for the...

  • Comparing Curt X5 5th Wheel Base Rail Adapters and Compatibility with Draw-Tite Gooseneck
  • The differences between the Curt X5 adapters is what they will fit. X5 adapter # C16220 fits Curt EZr Double-Lock gooseneck hitches. 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 System To Tow A Gooseneck Or Fifth Wheel Trailer With 2016 Chevrolet Silverado 3500
  • I do have a system that lets you tow either a gooseneck trailer or a fifth wheel. First, you will need the EZr Double Lock Underbed Gooseneck Trailer Hitch, part # C611-624. This system gives you a gooseneck hitch in the bed of your truck with a 30,000-lb capacity. You would then need an adapter, part # C16220 to install in the gooseneck ball opening in the bed of the truck. This gives you base rails for a fifth wheel hitch like part # C16245.

  • 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...

  • Curt Fifth Wheel Hitch Recommendation to Fit 2015 GMC Sierra 2500 with Curt Gooseneck
  • Sounds like you have the Curt EZr gooseneck hitch part # C611-624 installed in your 2015 GMC Sierra 2500 short bed based on what you described. To install a slider gooseneck hitch you'll need an X5 adapter part # C16220 so that you have a set of rails for the hitch to install in. Once that's in place you could then install the Curt A16 5th Wheel Trailer Hitch w/ R16 Slider # C16521 that you referenced which would be a great choice.

  • Will the Curt X5 5th Wheel to Gooseneck Adapter Fit a Truck with Spray-in Bedliner

However, there isn't a certain thickness that it has to be or can be. If you don't have a spray-in liner already then I would go with the minimum to be on the safe side.

  • The Curt X5 5th-Wheel Base Rail Adapter Plate # C16220 will fit your truck bed that has a Curt gooseneck hitch. What keeps the shank from twisting in the ball opening is the pin that inserts through the adapter. It's the same pin that holds the gooseneck ball in the hitch.

  • Will B&W Patriot 5th Wheel Hitch BWRVK3200 Fit Cut X5 Gooseneck-to-5th Wheel Adapter
  • The 16K B&W Patriot 5th Wheel Hitch # BWRVK3200 will fit into any industry standard 5th wheel base rails and all of the versions of the Curt X5 gooseneck-to-5th wheel adapters.

  • Gooseneck Hitch Compatible with Curt X-adapter and Curt Sliding 5th Wheel
  • The Curt EZr # C60611 you mentioned for your 2005 Dodge Ram 2500 is confirmed to fit your truck, but is not a confirmed fit with your adapter. That would require the Curt X5 5th-Wheel Base Rail Adapter Plate for EZr Double Lock Gooseneck Trailer Hitch # C16220. I reached out to my contacts at Curt Tech support to make sure we get you what you need and they confirmed that the hitch you need to be compatible with your components and your truck is the Curt Double Lock, Flip and Store...

  • Is there an Advantage to Going with the Curt A205th Wheel Hitch over the A16 for a 2016 GMC Sierra
  • I would not say that the Curt A20 5th Wheel Trailer Hitch w/ R20 Slider - Dual Jaw - 20,000 lbs Item # C16541 functions differently or smoother compared to the A16 # C16521. The advantage of going with the 20K hitch though is that if you ever plan on towing anything heavier than 16K you will be ready! The X5 adapter for your Curt EZr gooseneck hitch is # C16220.

  • Should there be 1 Inch of Play After Installing the Curt X5 Adapter
  • First, make sure that when using the Curt X5 adapter, # C16220, that you are putting it into a compatible Curt Gooseneck trailer hitch (Curt EZr double-lock gooseneck hitches). It is not designed to be used with any other hitch. If the locking pins are positioned properly and you get an inch of vertical movement then something is wrong and you would not want to use the adapter until the problem is fixed. One inch is way too much movement. The X5 adapter should only move vertically about...

  • Available Types of 5th Wheel to Gooseneck Hitch Towing Adapters
  • We carry many types of towing adapters for goose neck and 5th wheel hitches and trailers. Some of these adapters install in the goose neck ball hole, such as Curt X5 5th-Wheel Base Rail Adapter Plate # C16220 that fits their EZr Double Lock gooseneck hitch. This adapter provides the equivalent of base rails for any industry-standard 5th wheel hitch. Other adapters install on the ball itself, like the Demco Recon # DM8550045, which is a complete 5th wheel hitch, not just a rail adapter. You...

  • Availability of 5th Wheel to Gooseneck Adapter That Clamps to Gooseneck Hitch Ball
  • The Curt X5 Fifth Wheel Adapter you mentioned, part # 16310 isn't designed to attach directly to a gooseneck ball. The square shank of the adapter is meant to fit into the square hole where the ball would install into a B&W Turnover Ball Gooseneck Hitch. I've linked the instructions for you. If you currently have a B&W Turnover Ball Gooseneck Hitch, the # 16310 adapter would work great for you. You'd release and remove the gooseneck ball and insert the shank of the adapter in its place,...

  • Does Reese Goose Box Extend the Pin Box on a 5th Wheel Trailer
  • The Reese Goose Box # RP94720 doesn't add any length to the existing set up. The distance from the center of the coupler to the nearest bolt holes is approximately 18 inches. Any length added or lost is coincidental. What kind of gooseneck hitch does your truck have? You may be able to use one of the Curt X5 adapters and then use a sliding 5th wheel hitch such as # C16541 with it to get more clearance. X5 adapter # 16310 works with B&W gooseneck hitches with the exceptions for 2013...
