This hitch is rated for 20,000 lbs gross towing weight and a 5,000 lbs vertical load limit, giving you the strength to pull large fifth-wheel trailers with confidence. The sturdy steel construction and carbide powder coat finish provide a solid, long-lasting base you can count on for the long haul. It’s built to handle real-world towing stress while keeping everything stable mile after mile.
The rounded, interlocking dual jaws wrap fully around the king pin for tight, 360-degree contact. That design cuts down on rattle and movement compared to slide-bar hitches, making the ride quieter and smoother. The solid connection also means better stability when braking or maneuvering, so the trailer tracks right where it should without unwanted chucking.

You always know where you stand before pulling away. The color-coded indicator shows red when uncoupled, yellow when ready to couple, and green when locked for towing. It’s easy to see from the cab or bed, so you can confirm the jaws are set correctly without second-guessing. After uncoupling, the handle resets automatically to the ready-to-couple position for quick setup next time.

For slow-speed turns or tight backing situations, the S20 slider offers 12" of front-to-back travel to create more space between cab and trailer. The non-binding mechanism moves smoothly even on uneven surfaces and automatically latches in both directions, so you only exit the cab once during setup. It’s an easy way to gain turning clearance when every inch counts.
When you’re done towing, pop a single pin and lift off the head for easier removal without tools. The included plastic lube plate helps the king pin glide smoothly into place during hookups while keeping maintenance simple with two built-in zerk fittings for lubrication. This modular setup makes it manageable to remove or reinstall the hitch whenever you need your bed free.

Hi everyone, Aiden here with etrailer. Today we're going to be taking a look at these Curt Adapter Rails on our 2022 Ram 2500. Now that's going to be an adapter piece from the factory puck system if your RAM came with that in the bed and adapt it so you can use your pre-existing Curt Fifth Wheel with Slider Base. So if you already have that from a previous truck and you just mounted it up to your ISR rails, then this is going to be the piece that lets you use it with your new truck that has the prep package for towing. So rather than getting a whole new fifth wheel that's designed to work with that factory puck system, you can use what you already have, drop it into this adapter piece and keep using it as normal. Let's check it out.
So this is going to come with all the pieces and hardware you need to get things up and running. Your slider base is going to drop in to these rectangular slotted holes in each corner. Those are going to look very familiar to those who already have a fifth wheel set up and it's going to be the same size slot as those rails you maybe had before. And then this does come with the pins and clips to secure underneath with the tabs. Of course, you can upgrade to locking pins as well as locking pins here at the corners where this adapter attaches to the bed.
But out of the box, it's going to come with pins and clips and you can upgrade them later on if you decide to. Those quarter turn levers at each corner are going to be how we actually attach this into the factory puck system, where we drop this down in, turn that lever to lock the tab in and keep this from popping back out, keeping it very secure in the vehicle. And then when we're done, that's exactly how we remove it too, leaving nothing behind so you get full unhindered access to your truck bed. Now if you're starting from scratch and you need to build a whole fifth wheel hitch set up from the ground up, no worries, we've got plenty of kits here available at etrailer that you can find to suit your needs based on what kind of weight capacities you need and what features you need. But in all this is designed to work with Curt Sliders.
So whichever option you go with or if you end up piecing together your own kit, just remember that it's designed to work with Curt Sliders not necessarily other brands. And this is designed to work with sliders. So for our truck right here where we don't have a long eight foot bed, that's going to be perfect. That extra clearance from the cab is what we want and this is the piece that can get us there. But that'll do it for our look at these fifth wheel adapter rails from CURT on our 2022 Ram 2500.
Thanks for watching.
Ratings & Reviews
The hitch has worked very well. It is very sturdy, and I have had no problems. I would recommend this to someone with a short bed for the ability to slide the hitch.
On time shipping and delivery rated 4 stars for the fact of package was damaged and torn
Worked great took about 15 min to install happy with product shipped on time and received a day earlier than expected I staled on 2013 dodge Laramie longhorn 3500
Great hitch but even better service and shipping. Thanks for getting this to me in such a short time frame!
Great customer service and quick shipping. Showed up 5 days Early.
Easy install, did most myself but I needed my wife’s help with the plate mount. Took about an hour for install. Everything arrived in good condition, and all the hardware was accounted for.
Fast shipping
Exactly what I ordered and works perfect! Here is the A16 Curt attached in the photos. Easy and quick installation into the RAM puck system.
Looks great, Easy installation, Good quality.
I had a problem with ups losing one part and etrailer sent out another one. All the staff that I spoke with was great.
Product went on easily and looks great! Didn't even need to use the instructions really. Only complaint I had is with the shipping. It looks like the box was tossed from the truck of the shipper and between all the shipping hubs the box got trashed because of the heaviness of the product. I'd suggest a better means of securing the product in a heavier duty box as any shipping company won't Handle with care. Overall very satisfied!
This was an easy install. Very heavy and ready to pull my trailer!
An excellent experience with etrailer.com
Purchased and installed adapter rails for my Curt 5th wheel hitch. These adapter rails are rated for 24,000 lbs., and are "beefy". I could not be more pleased with the ease of installation and overall heavy duty construction of these adapter rails.
The product arrived 1 day earlier than promised. The instructions were decent, they could of been more inclusive of the different setups, the hitch and sliders didn’t reference how to interface with the Ram puck base. The rubber gaskets for the slider base didn’t fit with the Ram base due to their thickness. You need a 100lbs torque wrench(I rented one from Orielys). All the parts were present. The bad may not of been etrailers fault, but the boxes arrived like they were dropped out of an airplane. Amazingly, nothing was damaged.
Works very good and gives the extra space needed to back the camper in with out worrying about the cab of truck
Great products, excellent price, speedy (3 day) delivery and easy step by step installation instructions for my sliding fifth wheel hitch for my 2016 Ram 2500 short bed truck w/ factory tow prep package. I would highly recommend any of these products as well as the excellent customer service at etrailer.com
I bought a 5th Wheel camper on May 13th. On the 14 I started shopping for a 5th Wheel Hitch. I landed on etrailer’s site. I found what I wanted in no time. When I went to check out it said I should have the unit it 3 days. Which would be Friday. I needed to pick up my Camper on Monday. I called because I wanted to be sure it would deliver on Friday. They assured me I would have it Friday. I placed my order at 11am and by 3 pm I had an email saying the Hitch had shipped. To my surprise it arrived on Thursday. I’m very mechanically inclined and it took me about 2 hours to put the Hitch in my 2017 Ram 2500 with the in bed puck system. I did have to remove my bed liner which I will put back in at a later date. The installation went pretty smooth. I found it helpful to watch the videos on the installation. I picked up my camper on Monday and drove 100 miles home. So far so good. It’s going on 600 mile journey over the Memorial Day Weekend. I was very impressed with the customer service when I called and the very quick free shipping. Great Job etrailer.
I love the way it sits and fits in my truck. The instructions and installation were very clear and easy to follow and assemble. And there is still room to have my tool box’s and a chain between the 5th wheel and my tailgate. My tank cover fits perfectly over the top and my support bars don’t touch the 5th wheel either.
I am very happy with this 5th wheel.It works just like all the descriptions said it would. It will make pulling our camper a breeze.
I would recommend this hitch very highly. And will be recommending all my friends to this company for all future hitches.
First, the is a very heavy duty hitch. I watch the etrailer videos and the installation was simple. No issues at all. Second, I order from Matt who was very helpful an knowledgeable on the product. He said it would be delivered in two days. I laughed but low and be hold it was delivered in two days and the packing was incredible. I Thank you Matt for all you assistance.
Easy to install and works perfectly!

One year and zero issues after many trips pulling our 43ft toy hauler.
Curt A20 5th Wheel Hitch Fifth Wheel Hitch 2018 Ram 2500 This was not easy choice to make as I tend to try top save money. But with my truck and the puck system this has been an excellent purchase. The removable pin let's me pull the top of the hitch off while leaving the rest in the truck. This allows me to store it in front of the adapter rails. Then my roll up bed cover clears the top while the rest is still mounted. Dry, secure out of site out of mind while shopping or parked at RV park overnight. The slider allows the extra clearance to give you peace of mind you will not damage your truck while backing into tight spaces on a serious angle. Then of course the top comes off with that pin making the entire thing lighter to remove when taking the entire assembly out of the truck. IT is manageable but still better to use the tractor bucket or hoist as it is heavy duty. No issues and very happy with this purchase and the continued great service from etrailer! I pulled a 34 ft 5th wheel 1800 miles at average of 75mph. Did not even know the trailer was back there when the wind was not blowing. Thanks again for helping me put this package together and having the lowest price while doing it!
Easiest item I have ever installed on my truck. 4 bolts to set it up then dropped the entire assembly into the Ramming bed puck system. Plan to haul our 5th wheel rv with this. The slider will help if we get into tight area at the rv park. Simly to use. Love it
Cammi, my customer support person was awesome. I told her what I needed and she recommended to perfect hitch. I was impressed with her knowledge of their products and how fast it was delivered. Installation was simple as long as you follow the very well written directions.

My hitch is working great still. Easy to use no issues.
The hitch assembly is put together very well, heavy and rugged. Instructions did not match installation process needed to mount the slider to the ram oem roller adaptor. The angle cross supports are not needed on the roller adaptor as the roller assembly mounts on the adaptor directly. Other than that it is an awesome well made hitch.
This hitch was simple to install, easy to connect, easy to engage the slide mechanism, and easy to un-hitch. My review was originally lower, due to some poor packaging, which caused some minor damage in shipping. But the great people at etrailer.com were fast to respond and definitely made it right. Excellent customer service.
I previously owned the Curt A16. We needed a larger tow capacity so we purchased the A20 and decided to buy the S20 slider base as well. Too many sharp turning issues with our 6’8” Chevy standard bed HD3500 during maneuvering. The S20 slider should eliminate this issue. Also I love the design of both the A20 and S20.
