This heavy-duty 5th-wheel hitch is rated for 16,000 lbs gross towing weight and a 4,000 lbs vertical load limit, giving you the strength to haul large trailers with confidence. The sturdy steel construction and carbide powder coat finish hold up to long miles and heavy loads. Once hitched, everything feels solid and stable—exactly what you want when pulling serious weight.
The interlocking 2-jaw system wraps fully around the king pin for 360-degree contact. That tight grip cuts down on rattle and movement, giving you a quieter ride and a more secure connection than slide-bar models. The torsion head absorbs road shock and keeps everything steady through stops, starts, and turns, so towing feels smooth from the first mile to the last.
A quick look at the color-coded indicator tells you exactly what’s happening with your hitch—red means uncoupled, yellow means ready to couple, and green means locked for towing. You can see it from the cab or beside the truck, so there’s no guessing or climbing in to double-check. The handle locks for added security and automatically resets once you uncouple, ready for the next hookup.
For slow-speed turns in tight spots, the S20 slider gives you 12" of fore/aft travel to create needed clearance between your cab and trailer. It automatically latches in both directions and won’t bind under pressure, so maneuvering through campgrounds or backing into narrow spaces stays controlled and stress-free.
When it’s time to clear your truck bed, this hitch design lets one person remove it quickly. Just pull a single pin to lift off the head—no tools needed. Built-in zerk fittings make lubrication easy, keeping maintenance simple between trips while helping every hookup stay smooth and consistent.

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.
