This hitch is rated for 25,000 lbs gross towing weight and a 6,250 lbs vertical load limit, giving it the strength for serious fifth-wheel towing. The solid steel build and carbide powder coat finish make it tough enough for big trips and heavy loads. It’s designed to stay solid mile after mile, keeping your setup stable and reliable when pulling large trailers.
The interlocking two-piece jaw wraps completely around the king pin for full 360-degree contact. That means less rattle, less movement, and more security compared to slide-bar hitches. Every time you hook up, it feels tight and well-connected—exactly what you want when towing heavy on long runs. The design helps cut down on noise so the trailer tracks smoothly behind you.
With Curt’s color-coded lock indicator, you can tell at a glance if the hitch is uncoupled (red), ready to couple (yellow), or locked for towing (green). You can see it right from the cab or beside the bed—no guesswork or extra checking. And once you unhook, the handle resets automatically so it’s ready for the next hookup.
The torsion head self-aligns as you back in, letting the king pin glide smoothly into place with help from the included plastic lube plate. It pivots to absorb road shock for a quieter, more controlled ride. When it’s time to store the hitch or clear your bed, pull a single pin to lift off the head—simple enough for one person to handle.
Fine-tune your trailer level with built-in height adjustment from 13" to 17". Those extra inches make it easier to dial in proper clearance between the trailer and bed rails. The design lets you get your tow height right from the start so your rig stays level and steady on the road.
This fifth-wheel hitch is compatible with rotating pin boxes, such as the Reese Sidewinder, Reese Revolution, and 5th Airborne Sidewinder, only when used with a wedge (sold separately).

Hello, everybody. This is Jeff at etrailer.com. Today we're gonna take a look at the CURT Universal Carbide Black Finish Fifth Wheel Base Rails. Now, these base rails will install in your truck bed. And they provide the necessary attachment points for your fifth wheel hitch installation. Now, when these rails are used with the CURT's Custom Mounting Brackets, which we sell separate on a website, these rails will cut in half the time it takes to install your fifth wheel trailer hitch.
We mentioned the finish on this. I'm gonna zoom in and sort of show it. It's a carbide black finish, sort of like a matte black finish, so it matches the finish if you use it on the CURT Q5 20K Fifth Wheel Hitch. Now, these rails are universal, so they will work with the following fifth wheel hitches. They work with the CURT brand, the Draw-Tite, the Hidden Hitch, the Reese, and even the Husky.
This part here will include the two base rails. Now, we mentioned the mounting brackets, the custom mounting brackets, the hardware, and an installation kit is all sold separately. The length on these rails, if we put a tape measure on them from one end to the other, right at 43 inches long. But that should do it for the review on the CURT Universal Carbide Black Finish Fifth Wheel Base Rails.
Ratings & Reviews
Haven't installed 5th wheel rails yet but the service and shipping was great. Thank you
Took me a month, but I finally got the Curt A25 fifth wheel hitch in my truck and took it for nearly 150 mile trip to see how it would work. My wife and I both were amazed at how quiet and the bouncing, snapping, popping and cussing were all gone. This hitch is absolutely amazing. Before, when I just pulled out of my driveway, the old fifth wheel would snap and pop loudly several times. It was so quiet with the Curt A25 (new one), both of us looked at each other and looked back to see if the trailer was moving with us. (It was) Thank you to Curt for building it so well and to all of the people at etrailer that recommended it and ensuring it was all right.
I have pulled a 16,000 lbs 5th wheel over 13,000 miles with this hitch and no issues. It arrived with the package damaged and the handle bent. Etrailer quickly replaced the part. The base will rust if not covered. If you remain hooked up for an over night stay, you will need to lower your jacks to stabilize and prevent rocking do to the hitch’s design. Great product.
Brackets and rails were of high quality and were a perfect fit on my 2015 Dodge Ram 2500 HD, using the factory frame 'jig' holes for attachment
.
INSTALLATION NOTES: I looked up eTrailer's installation Video on the Dodge-specific custom brackets (in this case on a 2014 Dodge Ram 2500 HD). It was invaluable! It stated the task would take 1 and 1/2 hours for an expert; 3 to 4 hours for a novice. I am NOT an expert but have torn down and rebuilt an engine, replaced clutches and transmissions, and done brake jobs on my vehicles. Being admittedly slow because I want to be thorough (I wanted NO mistakes in drilling the holes needed into my new truck's bed), the task took about 3 days.
THE ISSUE: Though the under-bed brackets were perfectly made, there are two differences between the 2014 Dodge shown in the video (which I suspect was Gas engine equipped) and my 2015 Dodge 2500 (Cummings Diesel).
- CLEARANCE BETWEEN DIESEL FUEL TANK AND FRAME appeared to be MUCH less on my 2015 Dodge than the fuel tank on the 2014 Dodge (Gas?). The front left (in front of rear axle) frame bracket installation was WAY more difficult than in the video due to this clearance issue. A standard Torque wrench head with socket could not be fitted over the forward-most bolt due to this clearance issue between the Diesel fuel tank and the frame. I finally broke down and used a 'breaker' bar/socket combo and a piece of pipe to get that particular bolt tightened within a reasonable range of the proper torque.
- The rear axle suspension in the 2014 Dodge installation in the video was different than my 2015 truck. A significant mounting bracket for the new torsion bar was attached to the right-rear portion of the axle. I was adamantly against temporarily removing it (not even sure if I could have -- I THINK it was welded in place). Again clearance issues made installation of the right rear bracket quite a challenge for me.
Still I applaud eTrailer for making a high-quality kit that fits the bill!
the no drill kit was just that,no drilling except the bed and that was not too bad. I would reccomend this kit to any one installing rail for a hitch.....
Took about 5 hours to install but fits great using factory holes. Take your time lining up bracket before drilling. Only issue so far paint did flake and rust where hitch locks into bed rails. Will need ocassional sanding and touch up.
This product worked perfectly on my truck, bolt holes lined up nicely and was easy to install.
I've pulled my fifth wheel travel trailer on it and with the gooseneck adapter I've pulled some serious weight on my 32' gooseneck trailer without issue, very pleased with it.
It fit my truck and’s was exactly what I needed
Perfect fit,easy installation I’m happy with the product.
Product was great, installation instructions were well written and easy to follow.
I think after using it for about 5,000 miles of pulling our fifth wheel there must be a better system out that reduces the expected jarring from the movement of the hitch due to needed clearance to use pins.
I might have the hitch welded to the rails or find one that is not removable.
If you have a solid mount hitch, please let me know.
Simple install, didnt have to drill frame ,seems to be very heavy duty
Before even starting the install I was sure to read the directions a couple of times to make sure this was something I wanted to attempt on my own. I hadn't installed a hitch before but had assumed since it was a custom kit it wouldn't be too difficult. The directions stated that the total install time for the diy'er was 180 mins. I read through and took note of all the tools I was going to need. What I would have REALLY appreciated was a "tools required" list at the top of the instructions. I thought I had all the tools needed but at the very end when you get to the rear rail you need a 7/8" bit for the bottom of the bed support. I advise you have one at the ready. I had to hone it out with my 9/16 which was a giant pain. Everything else went really smooth. On my particular application I had a real hard time torquing the front right bed bolt on the rear rail to spec (110ft-lbs) as the mount for a cross-bar makes it nearly impossible to fit a torque wrench in. (I ended up having to use 3/8" drive extensions to go up inside the bucket and torquing it from the bottom.
Total time:(including a couple of breaks, meltdowns, and a bunch of swearing and a 2yr old hiding dad's parts) 180 mins. Touche' Curt Mfg., touche'...
Experience level of installer: None
This is something that the average person can do. Make sure to watch all the helpful videos here on etrailer.com, read through the directions before starting, and make sure you have all the necessary tools to help ensure your installation goes as smooth as possible.
Haven't had a chance to use the hitch yet but I got it installed without too much trouble. It took about 4 hours to install, the frame mounting brackets and rails, at a leisurely pace. The unit seems to be very sturdy and it is certainly built heavy. I'm looking forward to testing it out soon.
I haven’t installed yet, but looks to be very good quality and good installation instructions
Smooth transaction,Celiese made it very easy to order .
Great fit and product easy install did it in the dirt on drive way with no issues on 2016 Ram 2500
Excellent product. It took about 6 hours to install. The customer service is second to none and is highly recommended.
It is well built. Directions could have better illustrations. Putting handle together was the most difficult part of process. It dropped right into my existing rails. Have not hooked my fifth wheel yet, but very satisfied with the finished product.
The installation Kit for the Ram Truck was great. Had it installed within 3 hours and ready to use. picture is attached.
the service from etrailer was just great. Order shipped the same day and I had it on the 2nd day.
Ive been using this fifth wheel set up for about 5 months now and I don't have any complaints. I pull a 2022 Heartland Cyclone 4006 toyhauler fifth wheel. Loaded down its usually weighing between 18 to 20,000 lbs depending on what we are hauling.
Easy to order from etrailer with fast shipping. Ordered on Mon estimated delivery on Fri but came in only 2 days for a deliver Wed. Curt A25 hitch packaged very well good instruction easy assembly on tailgate filling installed and torqued in less that 30 mins.
Ordering from etrailer was a great decision! I got a confirmation email for my order within minutes and an email it had shipped in just a few hours. I was given an expected delivery date and it actually showed up a day early. I’m super impressed with the customer service! I bought a fifth wheel hitch and found an [online] video for my truck and hitch that was extremely helpful, especially since all the RV dealers in the area were two months out to install it. All in all dealing with etrailer has been a great experience and I will definitely be going back for any of my other RV needs!
Great people, great service and great products. Installation went as smooth as one could wish for with no mistakes thanks to the helpful advice given in the videos. Etrailer will be my only source for my trailer and hitch needs. A special thank you to Katherina.
Thank you for such a fine product!! We installed the fifth wheel hitch in my 2015 RAM 2500 Mega Cab without any problems. It took us 5 hours to complete the installation and all the brackets and bolts went in without an difficulties!!
A little tight to get into but overall a pretty simple straight forward install. Great quality and heavy duty material.
