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


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.

Has to much side to side play. Unit doesn’t lock down for a solid pulling experience. I had to go another route.


Comments
I will have our customer service team reach out to you. I do have a few recommendations for you. Bed liners and bed mats may affect the fit of the adapter and trimming may be necessary. This system will not work with fifth-wheel hitches or pin boxes that rotate, nor auto-slide fifth-wheel hitches.

Overall 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

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.

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.


Comments
As long as you do not have a B&W Patriot or a thick bed liner this should be compatible. I would just be sure that every fastener is tightened down and you should be good to go.

Review 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
