Install this adapter in the round ball hole of your Curt Double Lock gooseneck hitch to get above-bed base rails for your fifth-wheel trailer hitch. Universal rails provide attachment points in your truck bed for a standard fifth-wheel hitch.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
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.

Has to much side to side play. Unit doesn’t lock down for a solid pulling experience. I had to go another route.
Jenny N - 01/07/2022Overall the adapter works excellent. I did have a couple problems at first. First I had problems installing it. Not the adopters fault. My gooseneck receiver was too low. I had to loosen all the bolts then get a port of power underneath and push it up as far as I could, to get the adapter to lock in place. Then I retightened all the bolts. Then my hitch would not work with this Curt adapter. When sliding my hitch it hit the center dome of the adapter. Very fortunately I had a friend who had a Curt slider hitch. He sold it to me very reasonably and then everything work perfect. The first time I tried to remove the hitch and adapter assembly I could not get it unlocked. Had to put down pressure get the Bucket of my tractor, turn it unlatched. Had to do the same when installing to get it to latch. After pulling the trailer a couple times everything works excellent. And I actually like my new/used Curt fifth hitch over my previous Fifth wheel hitch.
Works great, lines up perfect, and when the rails get in your way trying to use your truck bed; you just pull it out.
After using this adapter for a year it's proven to be durable and easy to use. It's nice not having those rails in the bed of my truck! If there is a draw back it would be weight as far as installing it when you're ready to use it but you can't expect it to be light weight when it has to perform a job like handling a heavy fifth wheel. I recommend it highly!
Fits a little loose but all in all ez install great solution to utilize all Towing capabilities
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....
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
Very prompt service placed my order two days later my hitch arrived,no hidden costs,put hitch adapter in my truck in minutes and am ready to go. The sales person was very knowledgable and professional not pushy like some internet sales sites. Will definitely be my go to place for parts in the future.
I like Curt products this adapter was ez install I also bought the E16 5th wheel assembly now I can move my 5th wheel camper without worry Very fast free shipping
Great service
Charles was very helpful in answering my question promptly and saved us a lot of money another company led up to believe was necessary to spend. Shipping was fast and overall great experience. Will look here in the future when the need arises. Thank you!
Adaptor works great! Unless you have a bed liner the holes don’t line up. Have to use weight of trailer to pull pin and insert pin.
Great design great price all works as it should.
Review from a similar X5 in Gooseneck and Fifth Wheel Adapters
I love this hitch adapter. I mostly pull gooseneck trailer, but occasionally I need to pull a fifth wheel. Easy to get in and I haven't had any problems getting it back out when I was done with it.
Review from a similar X5 in Gooseneck and Fifth Wheel Adapters
Product fit perfectly with no problems. The 5th wheel assembly I already had fit on the adapter plate. Saved me from having to buy a new and expensive 5th wheel hitch. Great product.
Review from a similar X5 in Gooseneck and Fifth Wheel Adapters
The rails are well made. But on the heavy side I’m reluctant to pull it out. I would like them to stay put also, they tend to move around some with the B&W hitch.
Sierra K - 01/26/2022Review from a similar X5 in Gooseneck and Fifth Wheel Adapters
Great product! Ive pulled a 42' to Hell and back not one problem. It is heavy, but it's very solid. My fifth wheel hitch fit straight in. Way cheaper than having to put rails in if you have a factory ball hitch in the bed. Its It's also nice that it's removable so you can haul furniture, or things that can't sit crooked ect. Great product, should last forever. Definitely would recommend
