This hitch is made for serious towing. Rated for 25,000 lbs gross towing weight and a 6,250 lbs vertical load limit, the Curt A25 gives you the strength and stability needed for large fifth-wheel trailers. The sturdy steel construction and durable carbide powder coat finish hold up under heavy use while keeping the setup looking clean. It’s a solid foundation that feels secure every time you hitch up.
The rounded, interlocking two-piece jaw design completely wraps around the king pin for full 360-degree contact. This minimizes movement and cuts down on the rattle common with slide-bar models. The result is a quieter, smoother ride and a hitch that feels locked-in as you travel. It’s a noticeable difference in stability and towing comfort mile after mile.
You can tell exactly what’s happening with the jaws before you hit the road. The color-coded indicator shows red when uncoupled, yellow when ready to couple, and green when locked for towing. It’s visible from the cab or beside the truck, so there’s no guesswork or extra climbing around in the bed.
The fully articulating torsion head helps the king pin line up naturally as you back in, making hookups easier and more forgiving. It also suppresses road shock and reduces towing noise for a more controlled ride. The included plastic lube plate lets the king pin glide smoothly into place without extra grease messes.
When it’s time to clear your truck bed, you can pull one pin to lift off the head—easy enough for one person to handle. The hitch adjusts from 13" to 17" tall to match your trailer setup and includes two built-in zerk fittings for quick lubrication. It’s practical design touches like these that make setup, towing, and teardown straightforward every trip.
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.
