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 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.

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

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


Is an ok at best product in my opinion. I placed a brand new Reece 20,000 5th wheel hitch in the Curst Base Rail adapter to find that the holes for the pins did not line up the best. 3 of the 4 were close enough for the pins to go into, the last hole (front hole on right side) had to have approximately a 32nd and close to a 1/16th of an inch of metal removed for the pin to line up correctly and go through the hole. I have since purchased a different truck and installed a B & W gooseneck hitch and purchased a B & W rail system. The new B & W system is flawless and works great. I have attempted to sell the Curt X5 base rail adapter online with no success, currently it is simply taking up space in the corner of my shop.

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


Received the Curt X5 B&W turnover ball adapter yesterday. Would have been easier to drop in with two people but I was able to do it myself. Dropped right in, and in less then 15 seconds it was dropped and locked. Saved me lots of install time on 5th wheel rails. Set my RBW lil' rocker hitch on and pulled my 10,000 lbs 32' 5th wheel across town without issue. I feel that this is probably the strongest way to go when running a 5th wheel to turnover ball adapter, and its only about $*** which is a fraction of the cost for those other weird complex adapters that side load or flex. Customer feedback was great with optimal response time on my questions.

Managed to get my hands on a curt E16 5th wheel hitch and couldn’t be happier with the combination. The drop in weighs 100lbs and is honestly really easy to install. The hardest part is getting it from where it’s stored to the back of the truck.

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


The adaptor twists within the B and W gooseneck hitch causing at times a chunking noise that is rather unnerving although I am quite certain o am not going to lose the 5th wheel now that I know what is that's causing the noise ,it been very very difficult to convince my wife that there is not something drastically wrong.

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

Review from a similar X5 in Gooseneck and Fifth Wheel Adapters


This is just what I was looking for, already had Curt R5 slider hitch, put B&W hitch on new truck. Tried a gooseneck adapter, but too much flex. Went back to 5th wheel hitch. This adapter is built heavy, weighs over 100lbs by itself. I pull a 14,000lb toy hauler, with a F250 shortbed, needed the slider. I feel much safer with this product. Ordered from e.trailer, shipping was right on, only 3 days.

  • Gooseneck Hitch and Adapter Needed for Curt Q24 5th Wheel Hitch on a 2019 Ford F-350 Dually
    I do have a solution for you, but the Curt X5 # C16210 is designed for Curt Double Lock Gooseneck Trailer Hitches which have an existing slide bar that locks the gooseneck hitch ball in place. Since the Curt Gooseneck Hitch # C60700 is designed for a self-locking hitch ball, like part # C60629, it means that the Curt gooseneck isn't compatible with the X5. The only gooseneck hitch that fits your 2019 Ford F-350 Dually that you can use with an adapter is the B&W Turnoverball Underbed...

  • Does Install of Curt X5 Adapter C16210 Require Trimming of Bed Liner
    The Curt X5 5th Wheel Base Rails Adapter # C16210 that you referenced does require that the bed liner be trimmed out of the way so that it can fit properly. Since you have a bed liner and yours doesn't want to fit properly you'll need to trim it so that it can fit.

    The easiest way to determine whether you have the Curt X5 5th Wheel Adapter with Double Lock, Item # C16210, or the Curt X5 5th Wheel Adapter with EZr Double Lock, Item # C16220, gooseneck hitch is to look at the safety cable loops. If the safety chain loops are smaller than the ball hole and offset then you have the Double Lock, Item # C16210. If they are about as wide as the gooseneck ball hole and are centered with the ball hole then you have the EZr Double Lock, Item # C16220. See...

There are no custom fit adapter that we offer designed to specifically work with the Mor/Ryde pin box, but the # CAB-C5G should work well.

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...

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.

  • Can Curt X5 Adapter be Used with Automatic Sliding Fifth Wheel Hitch
    The Curt X5 5th Wheel Base Rails Adapter # C16210 cannot be used with any automatic sliding fifth wheel hitches since those hitches attach to the pin box and rotate as the trailer turns. You'd need to use a manual slider like the Reese 20k Slider part # RP30083. This has a round tube slider on it which will slide easier than a square tube and has a jaw design that holds the king pin tightly which allows for a very smooth and quiet ride quality.

    Sounds like you are trying to switch up your fifth wheel hitch setup so that you have more turning clearance.

    The Curt X-5 adapter # C16210 is designed to only work with Curt Double-Lock, Flip and Store gooseneck hitches and will not work with your Atwood gooseneck hitch. But we do have other adapters. Adapters such as the Pop Up you mentioned or the similar Convert-A-Ball adapter # CAB-C5GX1216 do not have a true offset. They will increase the distance between the back of the truck bed and the trailer but the pivot point remains the same meaning it will NOT help with clearance when turning.

I may have a solution for you however. Take a look at the Demco Recon Gooseneck to 5th Wheel Adapter, part # DM8550045. It clamps onto the gooseneck ball in the truck and provides a fifth wheel hitch. Please note that some trailer manufacturers will void a warranty if an adapter is used.
