This heavy-duty hitch is rated for 25,000 lbs gross towing weight and a 6,250 lbs vertical load limit. The steel construction and carbide powder coat finish give it the strength and durability needed for serious fifth-wheel towing. It provides a solid connection that feels stable mile after mile, ready to handle large campers or toy haulers without flexing or shifting on the road.
The interlocking two-jaw system wraps fully around the king pin, creating 360-degree contact that cuts down on rattle and movement. Compared to slide-bar models, this design keeps the connection tight and quiet while improving safety and control. The secure fit also makes coupling easier since the jaws self-align smoothly with the trailer’s king pin.
A quick glance tells you exactly what the hitch is doing. The color-coded indicator shows red when uncoupled, yellow when ready to couple, and green when locked in for towing. It’s visible from the cab, so you don’t have to guess if you’re properly latched. After disconnecting, the handle automatically resets itself to the ready-to-couple position so you can hook back up without fuss.
For tight turns at slow speeds, the non-binding S25 slider gives you up to 12" of front-to-back travel. That extra room helps prevent contact between your cab and trailer while maneuvering into campsites or driveways. It locks securely in both directions and moves smoothly without sticking, making it simple to use when conditions get tight.
When it’s time to clear your truck bed, pull one pin and lift the head off—it’s designed so one person can handle removal without special tools. Two built-in zerk fittings make lubrication quick, and the included plastic lube plate helps the king pin glide into place during hookup. With adjustable hitch height from 17-1/2" to 21-1/2", you can fine-tune your setup for a level, comfortable tow.

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.

One-year update: weve now put over five thousnad miles on our eleven-thousand pound fiver, and have had zero issues with the hitch. thats with numerous hitch-unhitch cycles, and a few long, steep grades to pull. The hitch works just as well as the day we installed it. The only shortcoming is its shear weight when lifting it out of the bed. Fortunately, the hitch proper lifts out of the spider mount by simply pulling one pin. That way, it can be removed in two pieces. Its still a two-person job, but is manageable. Thanks again, etrailer!

Tracking is showing that it has finally arrived. Can you please let me know if the tracking is correct or not? Sometimes, packages will deliver to the wrong address, so I also recommend you contacting your neighbors if you still have not received it to see if they got it in your place.
