Curt X5 5th-Wheel Base Rail Adapter Plate for EZr Double Lock Gooseneck Trailer Hitch

by: Chris H07/07/2017

Everything arrived in perfect condition. With a little trim of the bed liner the adapter fit perfectly as described. My Curt A-16 hitch looks great paired up with the gooseneck adapter. Ready to hit the road! 402615

Great product, so easy to install and works great. 400983

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.

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

I recently purchased a used '08 Ford F-350 with a B&S turnover gooseneck hitch. I wanted to use a Reese 16k hitch that I already own and put it in this truck without doing the typical bed rails to attach the fifth wheel hitch. I contacted Etrailer and they quickly identified the Curt X5 adapter to solve my issue. Ordered new adapter and in 3 days I had the unit and everything fit perfectly. This is the second time I have dealt with Etrailer in the last 6 months and I continue to be impressed with all aspects of this company. I'm glad I found Etrailer 6 months ago when I was looking for trailer hub and brake parts. I knew just who to turn to with my latest needs. Thanks Etrailer! 208661

Great. Works well to allow me to go from goose neck to fifth and back again with ease. Very satisfied!

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

Ordered Curt X5 Fifth Wheel Adapter for my B&W Square Shank Turnover Ball Hitch and received it in two days. Had it installed in my trucks in a matter of minutes. Just pulled out the ball and inserted the adapter, no holes to drill in my truck bed and simply unpin it and remove it to have full use of my bed. Love it! 192930

It is great! Just got back from a 4800 mile trip and unhooked my fifth wheel and pulled the pin and removed everything from my truck bed. The only way to go!

Review from a similar Curt 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. 266615

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

Nothing fancy, strictly utilitarian and simple. Built like a bomb shelter and shows no signs of wear. I pull a Keystone Laredo 298BH almost bi-monthly and this gives me the flexibility I need to switch hitch styles between trailers. If you need a completely flat bed for hauling then you still have it versus bolted on bed rails. Much safer than a 5er extension and doesn't void the warranty on your travel trailer if there is a failure. I shimmed mine off of the truck bed to take out the slop with 2 sections of round baler belting from a tractor supply store attached via industrial adhesive and it works beautifully. It weighs a lot so swap outs are a bit of a chore but i wouldn't want it to be built any lighter. Bravo on a great product 357271

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

After reading numerous favorable reviews on the goosseneck to 5th wheel adapter #16310 I decided to purchase one from etrailer.com. My entire experience has been truly outstanding. I ordered the adapter on Sunday night and Monday morning I received a phone call confirming my order and address. The order shipped on that same day and arrived on Thursday. I installed the adapter in my truck within minutes and installed my HUSKY slider hitch within minutes with absolutely no problems. I picked up my new 5th wheel and the adapter and hitch worked perfectly. I highly recommend etrailer.com and the Curt X5 Fith Wheel Adapter for B and W Square Shank Turner Ball Hitches-16310. 170741

I just wanted to say the people at etrailer are some of the best people to do business with. Me being someone who always seems to get broken or flawed items when i order online can with all honesty say i feel they went out of their way to make sure my adapter arrived in time for my trip and in excellent working order! I have looked thru their site and seen all the stuff they carry and if they have or can get it i will do business with nobody else. If you want a company that does business they way it's supposed to be done than you can't go wrong with these guys! Thank you so much and it's all my pleasure to give a 10star review.... 192401

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

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. 134542

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

I just purchased a used pickup that had a B&W square shank ball set up in it. I really was not looking forward to the headache of installing a rail kit, what with the drilling etc. that is required. I kept searching until I found this product. For a comparison: frame rail install with all drilling that's required, several hours; installing this, 30 seconds. It's definitely the way to go if you already have a gooseneck ball set up in your truck. I was also very impressed with how quickly the item arrived. I was expecting a week or so, instead it arrived in three days. I am very happy all the way around. 158746

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 261579

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

Have a truck with a goose neck hitch but needed an adapter to haul a 5th wheel trailer. This hitch is very easy to use, fits well in my bed (truck bed is very banged up and uneven from years of demolition/ remodel work and fire wood hauling), and is quick to place and remove. The adapter lays flush enough in the truck bed that it wouldn't affect most loads or cargo (i.e. Lumber, mulch/bark, fire wood, etc.) My 5th wheel hitch (Reese) fits perfectly with the hitch. I am incredibly pleased with all aspects of this product. Worth the price for the ease of use. 262334

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 Curt X5 in Gooseneck and Fifth Wheel Adapters

The X-5 is a heavy built, nicely finished adapter. It literally took me longer to open the box than to install it. I slipped it into the opening myself. I owned a Pro 15k which slipped right into the rails. I had assumed when I purchased this product (as it was advertised to fit a B&W turnover) that there was a built in offset to counter the typical 6" install towards the cab. After measuring my trailer it's appearant that a slider is now needed. It would be ausome if there was an option for an offset especially for the price. 336435

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

Heavy duty. But it does not drop into B & W under bed hitch far enough for the capture pin to engage the hole in the Curt adapter. I am not going to modify my spray in bed liner to solve this problem. Curt should make the hitch work without the need to modify a spray in liner. ( A larger hole in the Curt drop in shaft?) Maybe when I am able to drop the trailer onto the hitch it will engage the B & W under bed pin due to the extra weight. At this point I'm not satisfied . 345043

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

What a deal, much lower price then anybody else, extremely fast shipping! Just drop it in, set the hitch, good to go. When done, take out the hitch, take out the adapter and have a perfectly smooth bed for whatever. Appears to be heavily built, very solid and how much simpler can you get, drop it in the gooseneck hole, throw the lock lever and you're ready! Like everything else I've order from etrailer, top notch stuff at great prices! 420637

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

Excellent product, good build quality, it didn't work for me as a drop in and use it but etrailer was willing to make it right. My fifth wheel hitch bolted right in with no issues. Excellent how all pieces can be removed leaving a flat bed surface. Do not expect this to fit in 2017 F250 with B&W turnover ball (bwgnrk1117) as it will not lock in place since the ridges in the truck bed are different height than previous year trucks. 389696

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

5th wheel adapter plate fits perfect in ball socket. The hitch which I'am mounting to the adapter has a solid bottom, it will not allow the hitch to mount to the rails. I was wondering if you sold a 2" spacer kit # 46250 for a ts3 Trailer saver hitch? If so how much is it. Rubber Pads were put on backwards so the stuck to the box instead of hitch. can I get 4 pads?

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

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.

Etrailer did a great job of shipping very very fast received in just three days. The X5 it's built very sturdy and it is very heavy it seems to be very strong. The only issue that could be with this product is when you use it with a B&W hitch it seems to set it a little deeper in the bed maybe about 6 inches behind Center axle. If you don't have a slider hitch this could be a problem 245646

Great product and easy to install. etrailer staff was great. Shipping was fast. One note: if your goose neck pin doesn't fully engage due to a spray in bedliner, connect up to your trailer and the weight of the trailer should allow the pin to fully engage. After my first trip the adapter settled enough and the pin engages easily without the trailer weight. 230906

Received product very quickly within 4 days with the free shipping option. The adapter dropped right in. The only issue I had is two of the small rubber pads came off the bottom of the adapter and we're stuck to the cardboard so in useable. I put the 5th wheel hitch on the rails and everything lined up except the two pins on the cab side will have to be hammered in. 209303

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

Shank was too long. It bottomed out in the gooseneck hole an inch and a half at least before the rails touched the linex. Some modification was needed to make it work. Can't just drop it in and go.

This is so much better than having the rails permanently in my truck. The installation went well. Having to cut the heat shield is one of those moments on a brand new truck but it needs to be done.
