This adapter is specially designed to attach to the receivers in your Ford or Chevy/GMC's factory, underbed 5th-wheel towing prep package. The base then provides the attachment point for your Curt 5th-wheel legs or roller.

Had to replace my vehicle while on vacation. 2020 puck system was different than the 2025 puck system so I had to order a new base. Ordered the new base on a Friday and it was delivered the following Monday. Jacob was extremely helpful throughout the whole process. Package while extremely heavy arrived intact. Bolted rails together. Specs very tight on the 4 pins that hold the base to the hitch. Needed a little coaxing to get it pinned. Definitely a two person job. Would use e-trailers again in the future. Thank you for your speedy service.
I needed to move my in-laws 5th wheel trailer and didn’t have a 5th wheel hitch for my 2022 puck system. I wasn’t sure the new adapter would work on a 23 year old DrawTite hitch, It worked perfectly !!

Wow, I don't think I have ever seen a 23 year old hitch, before! That's awesome the rails worked for you. I'm impressed! You really had no issue and didn't have to finagle it at all?
Assembly and setup was super easy and quick. Seems super stout. I was worried the added 2 1/2 inches of height added by this would require some adjustments to the pin box. However once hooking up my trailer, no adjustments were necessary. Trailer is almost spot on level, and I am still maintaining 6.5-7 inches of bed side clearance to the trailer.

After a year of use, I have no complaints. It does its job just fine. I will also add for others in the market, my father and law has a 2025 Sierra 3500 that he upgraded to, and upgraded his standard 5th wheel hitch to a Andersen Ultimate for the factory puck system. I was able to compare side by side the puck style Andersen to the rail Andersenadapter I have. The height of the hitches are the exact same.

Easy assembly, easy installation , fit perfect, works perfectly. I have only used the hitch once. I don't see any issues going forward with this hitch adapter. Highly recommend it and e-trailer .

It's great to hear everything is working flawlessly for you Jon, and we appreciate your recommendation! Any fun upcoming adventures planned?
The Curt Adapter Rails were very simple to assemble and fit the truck perfectly. Brandon at etrailer was very helpful in answering my questions on would it fit my 2025 GMC 3500HD AT4, he was also able to tell me that it would work with my Pull Rite 2700 Super Glide hitch.
Thank you

Brandon will be happy to know everything worked out for you, Billy! Have you been on a trip with the new truck yet?
Easy to assemble and install. Love that it snaps into the puck system in the truck bed and allows me to remove the entire hitch using an electric hoist, easily.

Great product! Easy to install hitch and remove with this adapter. I no longer have to drive around with that heavy 5th wheel hitch in my truck.
Purchased a 2024 Silverado 3500 set up for 5th wheel with the PUCK connections. My previous truck had ISR rails and the PullRite SuperGlide 5th wheel hitch. The Curt adaptor is the perfect solution to avoid buying a whole new hitch.
The package arrived in good condition and on time. Upon opening the box I was extremely surprised how well it was packed, each corner had a metal bracket, there was a piece of plywood on the bottom and top and foam separating the parts.
The install was fairly easy, read the instructions, Chevy is one way, Ford another. The PUCK locking mechanism make a nice tight connection with very little adjustment needed. The rails fit in nicely and the bolts went in well, torqued as required.
I have not yet attached the PullRite hitch but if it fit the Curt ISR rails on the previous truck it should fit this one. With the Chevy 2500 I had, between the squat and ISR rail setup the 5th wheel was slightly lower in the front. With this Chevy 3500 suspension and the adaptor being about 2" higher I expect the camper to be level or slightly higher in front which works.
Very nice adaptor if you have the need, better than changing out a perfectly good hitch.
Well the package arrived on time but the box was damaged severly. Not sure if all the parts was in the box. After reviewing the items along with the instruction being ripped, all parts was present.
Like some other posts, followed instructions to the letter and hitch would not drop into rails. Loosened all the rails bolts, mounted hitch, and re-torqued everything. Puck mounting brackets were just off square a bit and twisted the rails when first installed. Either square ‘em up or alter instructions so it goes in first time. Installed in a 2022 Silverado 2500 6’10” bed. Loved the plan, set the rails first time in a few minutes (instead of waiting in a shop for four hours while someone else did the boring and cutting and such). Hitch has been in two other trucks with conventional rails and always fit. Coulda been a five star, but I am familiar with Curt and feel sure they will get it right.

Still satisfied, still recommend. Easy to move hitch in truck as one unit when I need more of the bed available, no further adjustments needed.
Definitely full fills the need of converting a GM puck mounting system to a previous std 5th wheel rail system mounted hitch. I currently have a Reese 20k 5th wheel hitch which is not compatible with the puck system. This conversion mounting system works well. Expect some additional noises from this until the parts fully mate. Also expect to lower your hitch ( via hitch or pin box) to avoid a nose up attitude on your trailer. Saved purchasing a new hitch, many $ savings. Happy with this piece of equipment ????
It was very easy to assemble and install. Maybe 10 minutes because I had to grab a wrench. It was also in question if it would work with other brands and in my case no problem working with my Reese hitch. It as able to email correspond and have my questions answered very quickly.
Well built. Using to adapt a Patriot 18k slider to Ford pucks. For this particular hitch, I did have to grind a small slot about 1/3 into the 2 front latching handles to clear a structural hitch component. Not Curt’s fault whatsoever.
Amy at etrailer is always great to deal with and curt packing was the best I've seen

She kills it here everyday! Thanks, Joseph :) I'll be sure she sees your review
Hello to all , I want to give a Big Thank You to Nick for his assistance in my 5th wheel hitch solution with my F-350 it has a overball style in it already....... problem was I already have a curt 5th wheel hitch that would'nt mount up to my truck So maybe a new hitch?? Nick listened to my problem and gave a solution with a Curt assembly that works for my application that work for my F-350 and the hitch I have already.... Installed it no problems and it worked out great for me so far..... Thx again

Thats awesome, Steve! I will be very sure to make sure Nick sees this review :) Thanks!
This rail set is awesome. It was packaged extremely well, went together perfectly and easily. This fit the pucks first time and only required minor adjustments to the castle nuts to snug the fit to the puck. Tip for others, When I put this together I left all the bolts finger tight until it was fitted to the pucks, torqued the bolts to specification and adjusted the castle nuts to snug. Easy. Curt Crosswing hitch dropped right in pins fit with ease.
Really wanted to give this 5 stars but it appears they didn’t try it with a hitch like mine. The flanges on the cross supports do not allow my hitch to seat down onto the support tubes. Thus the hitch holes will not line up with the tube holes and the pins cannot be inserted. I fixed it by taking a sledge hammer to the ears on my hitch until the holes aligned. I shouldn’t need to do that to something this expensive.

It is a shame that you had to use a sledgehammer to use the rails. I wanted to ask which brand of hitch do you have?
This rail adapter work like i wanted it to. Saved us from having to purchase a New 5th hitch
Good service and fast shipping, very good quality and no problems to install, thank you.
The adapter itself appears to be solidly built and if it were compatible with my B&W Companion Slider 5th Wheel Hitch I'd probably be giving it a 5 star review. The issue is I purchased a 2019 GMC Sierra 2500 HD Crew Cab Denali back in'19 and with the standard short bed truck I wanted a "Slider" style hitch For pulling our 38'Grand Design Solitude. I loved everything about the truck/hitch/trailer set up. With the new technology of additional torque, higher weight towing capability along with the camera array that makes your coach practically invisible. So, you guessed it, I purchased the 2025 exact truck and trim model but what I didn't know was the GM decided to change the truck bed OEM Puck system in 2020 to accommodate, well I don't know why they changed it but the pattern and dimensions were now no bueno as far as towing my rig without some kind of changes being to my system which meant a minimum of around $XXX for an adapter for the base of the hitch along with some additional hardware or $XXX+ for a new complete hitch. After doing my due diligence of researching the various options and reviews I opted to go with the Curt Base Rail Adapter, Model #16027 which is compatible with my '25 GMC/GM/Ford OEM Puck system (verified through numerous reviews as well as eTrailer's sales rep when I placed the order), or so I was lead to believe, that it would be perfect for my truck and hitch mounting problem. However once I installed it there were numerous issues. The keyway on the legs on my hitch were too big to fit in the puck holes (1" thick keyway vs. the 1/2" slot on the adapter rails), the slots for the legs were still off slightly and the handles on the hitch base would be off by 90 degrees when in the locked position.
solutions So I have now reached out to B&W for their suggested remedy to my issues. I'm expecting it to be one of the higher dollar resolutions i.e.- new base with the correct OEM puck orientation (around $XXX) or a new complete hitch ($XXX+). Hey, I only wanted to add a new truck to the equation... Sorry for the lengthy review but ask anyone that knows me, they'll tell you that's how I tend to roll. If you ask me what time it is , I'll tell you how to build a clock.
Easy to assemble only 8 bolts required. Puck attachments come pre installed.

That's awesome to hear, Adam! Thanks for including a photo of the install, it looks good.
Have not gotten to tow yet but everything went together fairly easy. One major disappointment was the shipping and the packages were dumped in my driveway. Also it was not clear if I should use the spacers on this while installing the A16 hitch. I tried to get them to fit but could not get the pins to fit so I removed the spacers.
Received my order went to put it together and the pin holes on the rails don’t lineup with the GMC three and five on both sides. Try to get a hold of my rep Cel but apparently she’s gone until after May 20 of 2025 called and left her a message so then I was transferred to another representative Nicole talk to her asked for videos pictures that she would get back to me called twice left two messages sent videos at this point I just wanted an RMA because I had a trip planned for this weekend and now I can’t even do that cause I won’t be able to haul my fifth wheel trailer so if somebody can just get back to me, I would appreciate it so I can return this and either get my money back, which is probably what I wanna do at this point since I’m having a hard time getting in communication with the people that are supposed to help me
Easy install, great fit. Haven't pulled the 5th wheel yet....but if it goes well,I will be completely satisfied. Easy ordering, and very quick shipping. Love your company
Arrived on time. Well packaged and easy installation
After purchasing a new truck, I needed an adapter for the Chevy puck system without buying the entire 5th wheel hitch, this fit the bill. Heavily built and easy to install. The only thing I would recommend is to use larger cotter pins because the ones that came with assembly would not engage the castle nuts.
Condition: Like New

Hey Paul. I'm glad that Jacob got you all hitched up. What kind of 5th wheel are you towing?
