This setup is designed for big fifth wheels that demand strength and steady control. With a gross towing weight of 20,000 lbs and a vertical load limit of 5,000 lbs, the solid steel build gives you confidence pulling serious weight. The carbide powder coat finish helps protect against scratches and rust over time, while the fully articulating torsion head smooths out road shock for a quieter, more stable tow.
The interlocking two-piece jaw wraps completely around the king pin for full 360-degree contact. That design cuts down on rattle and movement so the connection feels tight and controlled from the start. A glance at the three-point color-coded indicator tells you what position the jaws are in—red for uncoupled, yellow for ready to couple, and green for towing—so you always know you’re properly locked before hitting the road.


For tight maneuvering at slow speeds, the S20 slider gives you up to 12" of front-to-back travel. That extra space helps prevent the trailer from contacting the cab during sharp turns. It automatically latches in both directions, meaning you only need to step out once to set it. The non-binding design moves smoothly even under pressure, giving you reliable clearance and a solid, quiet sliding motion every time.
When you’re done towing, clearing your bed is simple. The fast one-pin head removal lets one person lift off the top section without tools, while the hitch base drops right into puck receivers and locks in place with quarter-turn anchors. The modular design makes storage easier on your back and keeps your truck ready for whatever comes next.
Keeping this hitch in top shape is straightforward thanks to two built-in zerk fittings that make lubrication quick and clean. The included plastic lube plate helps the king pin glide smoothly into position during hookup. Combined with its sturdy steel frame and limited lifetime warranty, this setup is built to last through countless miles of towing.

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at this Curt 5th Wheel Adapter Rails for your Chevrolet and GMC trucks that have the factory 5th wheel prep package. Now, this is a custom fit part, it is designed to fit the 2016 to 2019 Chevrolet Silverado and GMC Sierra 2500 and 3500 trucks with the OEM prep package, and on a custom fit part like this, I do like to recommend for you to go to our website, use the fit guide, put in your year and model vehicle, and it'll show you if this will work for your application. Now, this will let you easily transfer your existing 5th wheel hitch from a previous truck to the new factory underbed puck equip trucks. This will convert the factory underbed system to the standard 5th wheel base rails. Now, they do use a quarter-turn anchoring system for quick installation and removal, wanna zoom in to show you a close up of that.
We're just gonna do one corner, but you'll do this at each corner, there's four corners. But basically, when you go to install this, what you'll do is pop off this clip, and then you'll rotate this handle out a quarter of a turn, and when you do that, if you noticed right down here, this tab is rotating also, so that'll open it up. You'll do that at each corner, and now, you're ready to drop this whole system right into the underbed factory system. Once you drop it in, the tabs will drop into place, you'll rotate this handle back just like that, and it rotates that tab to lock it in, and again, you'll do it at all four corners. Once you get it locked in, put your pin and clip back in, and that locks the handle in place, you're all ready to go.
You can also adjust the anchors right here, these can be adjusted to help eliminate any chucking between the legs and the underbed platform, right here you can put a wrench in here, there's a cotter pin that you can pull out, put a wrench in here, and tighten it up or loosen it, whatever you need to. Now, this does also include the four pins and clips that'll allow you to secure the 5th wheel to these adapter rails. Again, the specs on this, it is designed to fit the Chevrolet and GMC trucks with the 5th wheel prep package, capacity on this is 30,000 pounds gross towing weight capacity, and it has a 7,500 pound vertical load limit. But that should do it for the review on this Curt 5th Wheel Adapter Rails for the Chevrolet and GMC trucks with the factory 5th wheel prep package..
