This hitch is rated for 20,000 lbs gross towing weight and a 5,000 lbs vertical load limit, giving you the strength to pull large fifth-wheel trailers with confidence. The sturdy steel construction and carbide powder coat finish provide a solid, long-lasting base you can count on for the long haul. It’s built to handle real-world towing stress while keeping everything stable mile after mile.
The rounded, interlocking dual jaws wrap fully around the king pin for tight, 360-degree contact. That design cuts down on rattle and movement compared to slide-bar hitches, making the ride quieter and smoother. The solid connection also means better stability when braking or maneuvering, so the trailer tracks right where it should without unwanted chucking.
You always know where you stand before pulling away. The color-coded indicator shows red when uncoupled, yellow when ready to couple, and green when locked for towing. It’s easy to see from the cab or bed, so you can confirm the jaws are set correctly without second-guessing. After uncoupling, the handle resets automatically to the ready-to-couple position for quick setup next time.
For slow-speed turns or tight backing situations, the S20 slider offers 12" of front-to-back travel to create more space between cab and trailer. The non-binding mechanism moves smoothly even on uneven surfaces and automatically latches in both directions, so you only exit the cab once during setup. It’s an easy way to gain turning clearance when every inch counts.
When you’re done towing, pop a single pin and lift off the head for easier removal without tools. The included plastic lube plate helps the king pin glide smoothly into place during hookups while keeping maintenance simple with two built-in zerk fittings for lubrication. This modular setup makes it manageable to remove or reinstall the hitch whenever you need your bed free.

Hi everyone, Aiden here with etrailer. Today we're going to be taking a look at these Curt Adapter Rails on our 2022 Ram 2500. Now that's going to be an adapter piece from the factory puck system if your RAM came with that in the bed and adapt it so you can use your pre-existing Curt Fifth Wheel with Slider Base. So if you already have that from a previous truck and you just mounted it up to your ISR rails, then this is going to be the piece that lets you use it with your new truck that has the prep package for towing. So rather than getting a whole new fifth wheel that's designed to work with that factory puck system, you can use what you already have, drop it into this adapter piece and keep using it as normal. Let's check it out.
So this is going to come with all the pieces and hardware you need to get things up and running. Your slider base is going to drop in to these rectangular slotted holes in each corner. Those are going to look very familiar to those who already have a fifth wheel set up and it's going to be the same size slot as those rails you maybe had before. And then this does come with the pins and clips to secure underneath with the tabs. Of course, you can upgrade to locking pins as well as locking pins here at the corners where this adapter attaches to the bed.
But out of the box, it's going to come with pins and clips and you can upgrade them later on if you decide to. Those quarter turn levers at each corner are going to be how we actually attach this into the factory puck system, where we drop this down in, turn that lever to lock the tab in and keep this from popping back out, keeping it very secure in the vehicle. And then when we're done, that's exactly how we remove it too, leaving nothing behind so you get full unhindered access to your truck bed. Now if you're starting from scratch and you need to build a whole fifth wheel hitch set up from the ground up, no worries, we've got plenty of kits here available at etrailer that you can find to suit your needs based on what kind of weight capacities you need and what features you need. But in all this is designed to work with Curt Sliders.
So whichever option you go with or if you end up piecing together your own kit, just remember that it's designed to work with Curt Sliders not necessarily other brands. And this is designed to work with sliders. So for our truck right here where we don't have a long eight foot bed, that's going to be perfect. That extra clearance from the cab is what we want and this is the piece that can get us there. But that'll do it for our look at these fifth wheel adapter rails from CURT on our 2022 Ram 2500.
Thanks for watching.
