This Curt A25 fifth-wheel hitch gives you the strength and stability you want when pulling big trailers. It’s rated for 25,000 lbs gross towing weight and 6,250 lbs vertical load, so it’s ready for those long hauls with heavy campers or toy haulers. The hitch mounts above the bed rails and has a durable carbide powder coat finish that stands up to tough use. With a solid, heavy-duty steel build, it feels planted and secure every time you hook up.
The interlocking two-piece jaw wraps fully around the king pin for 360-degree contact that locks the trailer tight. That design cuts down on rattle compared to slide-bar hitches, giving you a quieter, more secure towing feel. Each trip feels steady from start to finish since the jaws hold firm without extra play or noise. The built-in lube plate helps the king pin glide smoothly into place during hookup, adding to that easy, consistent connection.
Before hitting the road, you can see at a glance whether you’re ready to tow. Curt’s three-point indicator uses color coding—red for uncoupled, yellow for ready to couple, and green for towing—so you always know where things stand. The indicators are visible from the cab or at the hitch itself, helping you confirm your setup before pulling away.
Hooking up is easier with the self-aligning torsion head that naturally centers under the trailer and flexes for smooth coupling. The torsion head also helps control movement on rough roads for a quiet, stable ride. When it’s time to clear your bed, pull a single pin to lift off the head—light enough for one person to manage. It’s a straightforward design that keeps setup quick and teardown simple.
Getting your trailer level is simple thanks to the 4" range of height adjustment built right in. You can fine-tune clearance between your bed rails and trailer overhang so everything stays balanced during travel. With its sturdy construction and straightforward adjustability, this hitch stays consistent trip after trip without fuss or rework.

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.
