This hitch is made for serious towing. With a gross towing weight rating of 25,000 lbs and a vertical load limit of 6,250 lbs, it’s built from sturdy steel and finished in a durable carbide powder coat to handle tough hauls. Whether you’re pulling long miles or loaded heavy, the solid build gives you that rock-steady feeling every time you hitch up.
The interlocking 2-jaw system wraps fully around the king pin for 360-degree contact. That design keeps the connection tight and cuts down on rattle compared to slide-bar models. It’s quieter, smoother, and feels locked in when you pull away—just the kind of connection that gives you confidence towing big fifth wheels down the highway.


Curt’s color-coded indicator tells you exactly what position the jaws are in—red for uncoupled, yellow for ready to couple, and green for locked in and ready to tow. The indicator is easy to see from the cab or the side of the bed, so you can double-check at a glance before hitting the road. The handle is lockable with a padlock (sold separately) and resets itself after you unhook, so it’s ready for the next trip.

The torsion head moves with your trailer for controlled coupling and a stable, quiet ride. By suppressing road shock and reducing towing noise, it helps keep things steady on uneven pavement or long stretches of interstate. Paired with the included plastic lube plate, hookup stays smooth and consistent every time.
When it’s time to clear out your bed space, just pull one pin and lift off the head—no extra tools needed. The fast one-pin head removal makes it easier for one person to handle without special equipment. With 4" of height adjustment built in, you can also fine-tune your setup between 13" and 17" for proper trailer leveling before you hit the road again.

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.

I have pulled my 5th wheel over 5k miles since installed. The plates and bolts have not rusted and still look great.

Easy to install, excellent product. My 14Yo son and I removed the bed, replaced the bed struts and installed the new hitch. Perfect fit

I think it is impressive and tells you that CURT HITCHES are confidant in there products, that they reach out after a year and ask how it is performing. How time flies. Its been another year and my hitch is still in the box it came in. I sold the truck I was going to put it on and have not replaced it with one that I plan to hang onto long enough to bother installing it on. I will have another F series truck though as my forever truck, that this will fit. At that time I will proudly install this hitch. I cant wait!

For clarification according to the installation instructions the fit note regarding 2003 and earlier models was in reference to competitors 5th wheel systems, and not in reference to the vehicle fit. For this kit the passenger side frame hanger will need to have holes drilled for complete installation.
Do you have a question about this 5th Wheel Hitch?
