This heavy-duty setup is built to take on big fifth wheels with confidence. Rated for 25,000 lbs gross towing weight and a 6,250 lbs vertical load limit, it’s made from sturdy steel with a durable carbide powder coat finish. Every part feels solid and secure, so long hauls stay steady whether you’re on smooth highway or rougher roads. It’s the kind of hitch you can count on when you’re hauling serious weight day after day.
The interlocking 2-jaw system wraps completely around the king pin for full 360-degree contact. That tight fit cuts down on rattle and movement compared to slide-bar designs and gives you a quiet, stable ride. The fully articulating torsion head helps the trailer move naturally with the truck, suppressing road shock and reducing clunking noise. It all adds up to a more controlled towing experience that feels smooth from start to stop.

No guessing or second-checking—just look at the color indicators to see where you stand. Red shows uncoupled, yellow means ready to couple, and green confirms you’re locked in for towing. The indicators are visible from the cab, and once you unhook, the handle automatically resets so it’s ready for your next hookup. This simple system makes it easy to confirm a secure connection before you pull away.

For slow-speed turns that need extra clearance, the built-in S25 slider delivers 12" of front-to-back travel. It automatically latches in both directions and slides smoothly without binding, keeping enough space between cab and trailer during sharp turns. That means better maneuvering when backing into campsites or navigating tight areas, all while staying securely locked in place once you’re straight again.
When it’s time to unload or store the hitch, the fast 1-pin head removal makes it easy for one person to handle. The design breaks down quickly without tools and includes base rails and mounting kit for simple installation. With 4" of height adjustment built in, you can fine-tune your setup for proper clearance and level towing every time.

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.

Rails work flawlessly. Between two hitches and a GN adapter all have fit without any problems.

Hi Sam, Thank you for your review! If your truck does not have the OEM gooseneck package, then I would recommend getting the B&W Companion 5th Wheel Trailer Hitch - Dual Jaw - 20,000 lbs Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches, part BWRVK3500-5W and Part BWGNRK1384 . This setup will give you a much more solid connection to your truck and should help eliminate the jarring you are talking about.

Great, easy installation, great instructions, a little time consuming but that was expected for a excellent hitch specific installation.
