Fits a little loose but all in all ez install great solution to utilize all Towing capabilities 752655

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

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. 825239

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.

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


Received product 4 days after ordering with free shipping. Seems really well made. No noises or clunks when towing. It dropped right in to my b&w gooseneck and my Reese 5th wheel dropped directly into it. Good product. 515924

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


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

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

It took about 10 minutes with a lifting device or two people could install easily. The best is it's made in the USA . The fifth wheel hitch fit perfectly. GREAT product. 665744

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


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

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


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

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


Works great. I would rather install a B&W gooseneck hitch and use this easy conversion for the 5th wheel than install the fifth wheel hitch. 602731

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


Fit is very tight and took some effort for B&W rod to slide through. May take an extraordinary effort to extract from mount. I'll try some day and let you know. For now it will stay. Needless to say, simply installing and uninstalling is not easy. I think if the hole for the B&W rod were slightly larger it might be easier to install and uninstall. 582599

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


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
