This Curt A25 fifth-wheel hitch is engineered to handle serious hauling—rated for 25,000 lbs gross towing weight and a 6,250 lbs vertical load limit. The sturdy steel construction and durable carbide powder coat finish give it long-term strength for pulling heavy trailers. With this much capacity, you can tow large 5th wheels knowing the hitch underneath is built to take it.
The interlocking two-jaw system wraps completely around the king pin for full 360-degree contact. That design eliminates the loose fit and metal slap that slide-bar hitches can have. The result is a quieter, more stable ride that feels solid from hookup to highway speed. It’s the kind of secure connection that keeps both truck and trailer tracking smoothly together.


Before pulling out, you can tell exactly what your hitch is doing with just a glance. The color-coded indicators—red for uncoupled, yellow for ready to couple, green for towing—make it easy to confirm the jaw position from the cab or beside the truck. And when you disconnect, the handle automatically resets itself to the ready-to-couple position so you’re set up for next time.
The articulating torsion head self-aligns during coupling and cushions movement on the road. That built-in flex helps control shock and cut down on noise so towing feels smoother and more predictable. Backing in or pulling out, it reacts naturally to trailer motion and keeps things level across uneven ground.
When you’re not towing, removing this hitch is quick thanks to its fast one-pin head release that one person can manage. The included base rails make installation straightforward, and the plastic lube plate helps the king pin glide smoothly into place when you’re ready to connect again. It’s a setup designed for both heavy work and easy storage between trips.
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.

I like the fact that it is light to handle by myself when I take the head off the brackets. I find it easy to open the jaws when in no load, but to disengage the jaws when I take trailer off it is hard to open the jaws. From the above it is much more difficult than my experience with previous Reese hitch, but I like the fact it is so much lighter than the Reese. I guess I just need to get used to it.
Do you have a question about this 5th Wheel Hitch?
