This hitch is rated for 20,000 lbs gross towing weight and a 5,000 lbs vertical load limit, giving you the strength you need for big fifth-wheel trailers. Its sturdy steel construction and carbide powder coat finish create a solid base that stays steady under heavy loads. Whether you’re heading out for a long haul or just moving camp, you can count on consistent performance every time you hitch up.
The interlocking 2-jaw system wraps completely around the king pin for 360-degree contact, holding it tight with less rattle than slide-bar models. That full contact means less movement and a quieter ride down the road. The design gives you a strong, locked-in feel that inspires confidence while towing.
A quick look at the color-coded indicator tells you what’s happening at the jaws—red for uncoupled, yellow for ready to couple, and green when it’s locked for towing. The lock indicators are visible from the cab, so there’s no guessing or climbing into the bed to check. The handle also self-resets after uncoupling, so it’s ready to connect again when you are.
For slow-speed maneuvers or tight backing situations, the S20 slider moves the hitch up to 12" fore and aft to help maintain clearance between your cab and trailer. The non-binding design latches automatically in both directions and moves smoothly so you can turn without worrying about contact. It’s built to make short-bed towing more predictable and controlled.
When it’s time to clear out your truck bed, the fast one-pin head removal makes it possible for one person to lift off the top section without tools. Two built-in zerk fittings make lubrication easy, and the included plastic lube plate keeps the king pin gliding smoothly into place at hookup. It’s a solid setup that’s simple to maintain and take apart when needed.

Hi everyone, Aidan here at etrailer. Today we're gonna be taking a look at and showing you how to install this replacement fifth wheel head for the Curt A20. This is going to be just the head assembly here today. So if you already have a sliding base or the legs for it, and you're looking to replace a broken or damaged head, or maybe you're just adding it to a sliding base, like the S20 we're using today, then this is gonna be the one for you. If you need the full kit, be sure to check out one of those full kits on our website. But as for this replacement head, let's check it out.
This is gonna operate just like your standard A20 fifth wheel head with the 360-degree dual jaw design. It's gonna get full contact around the kingpin here and those jaws are controlled by this lever on the outside of the fifth wheel hitch. We can unpin this handle right here. The pin could be swapped out for a padlock, if we wanna keep it secured when you're not around. Pull the handle out and back to open up those spring loaded jaws, and then we can back up to our fifth wheel.
That will drop into place. The kingpin will slide in. And it'll snap into place and you can see that 360-degree contact. Repin that handle or relock it back up to secure it, and then we're ready to hit the road. Now as we're hooking up, you probably saw a lot of movement in the fifth wheel head here.
Now it's by design. It's got a torsion system built into it, which gives us front to back, side to side, and even diagonal movement, really all around in a 360-degree motion. It can move around and adapt. So what it's gonna do is a number of things. It's gonna help guide the kingpin in so if we're not perfectly backed up to our trailer, this can kind of move and meet the kingpin where it's at to make hookup a lot easier.
But then when we're driving too, that's gonna act as a shock absorber, helping to reduce the hitching and just any of that road shock we're experiencing going down the road, but also limiting noise. To keep things operating smoothly, we've got our Zerk fittings located on the jaws here, so you can apply grease and keep them operating smoothly for a long time. The indicator at the back, visible from the cab of the truck will let us know if we're properly latched and coupled ready to tow. So we right now, we've got it locked in ready to tow. I'm gonna pull the handle out and back. And you can see right now we're in the coupling mode. And as I bring that dummy king pin back in, it's not fully coupled yet. And when it finally snaps in, (wheel head snaps) you can see it's got that green indicator. We can pin it in place and then we're ready to tow. So it's nice that you have that built-in and then it's visible from the cab of the truck. As for your weight capacity here, the fifth wheel itself can handle 20,000 pounds of gross towing weight and 5,000 pounds of your vertical load limit. Be sure to check on if you're using a sliding base like this one that it can handle that weight as well as your truck and go by the lowest rating component in your whole system. All around, you got a very durable steel construction with a carbide powder coat finish on top to help it resist rust and corrosion over time. Now that doesn't make it immune to things like scratches because that can scratch away the finish and cause it to rust and corrode quicker. But your kit does come included with a grease plate here that will slide in between the head of the fifth wheel with your kingpin in the middle here and help reduce that metal and metal contact. Keeping the head of this hopefully looking new for a lot longer and keeping those scratches and scuffs away. If you don't wanna leave this in your truck bed all the time, getting it removed can be a bit of a pain because of how heavy it is, But the head will separate from the main body here with this pin and a very large pin running through the center of everything. That is completely removable so that we can take the head on its own and lift it from the main body. So it's a lot easier to get in and out of the truck bed on your own like this. And if we look a little closer there where the pin runs through, you can see those rubber isolators that help dampen that impact and act as shock absorbers when we're going down the road. Now whether you're upgrading or replacing your existing head, it is going to be a very straightforward installation process. You will need a torque wrench for it, but aside from that everything's pretty straightforward and easy to do straight out of the box. So let's check out that process now. It comes pretty much fully assembled in the box. You will only need to attach the handle to the head, but I chose to also separate the head from the main body here, just to lighten the load a little bit and make it easier to attach. For our application today, we're attaching it to our sliding base here, the S20. So I'm just gonna get it dropped in place. And then, loosely get these bolts installed, line them up through the outer holes at whatever height setting we want, (metal clanging) and then attaching the nuts on the inside. (metal clanging) And at this point, once you've got it set to your proper height, you can tighten it down and torque it to the specifications found in your instructions. (metal clanging) (wrench rattling) If you don't have a torque wrench at home, they are pretty easy to rent, or you can find them here at etrailer. And repeat that process for all your other hardware. And then the head simply drops in place in the center and secures with the large pin feeding in through the back to the front. And then secures in there with this pin and retaining clip at the front. Now you're ready to hook up. And as far as the replacement head for the Curt A20 goes, that's really all there is to it. It's a very simple installation process. It comes with all the hardware you need. So if you already had an A20 fifth wheel hitch and you're just looking to replace a broken or damaged head, this is gonna drop right into place and do that for you. Or maybe you've got the S20 slider like we do here and you've got one of the kits maybe with the A16 and you're looking to upgrade the head to really max out the weight capacity potential of the slider itself. You can do that too. Like you see it is dropped in place Bolt it in with the included hardware and you're good to go. But that'll do it for our look at an installation of this Curt A20 fifth wheel head replacement. Thanks for watching.
Ratings & Reviews
The product is great and if you put the puck rails together write the system goes together easy, my only complaint is with UPS my boxes where damaged badly and some of the bolts and one hitch pin was missing. I went to the local store and they had everything I needed so I was only out an extra $25.00 for the parts, considering I got the system for a lot of money and the dealers here wanted $2500.00 to $3000.00.
As always etrailer was a pleasure to work with. The box was damaged during shipping and a bag of screw fell out. One call to Etrailer and the problem was solved. Took about 30 minutes to install. (Half of that was finding my torque wrench).
Can not believe the condition of all items as they were received from shipping carrier. Boxes torn apart, bolts and nuts all scattered. Even 5th wheel hitch had rubber on handle cut. Found nuts and bolts on ground next to where the shipping carrier had unloaded items. Luckily found all nuts and bolts after searching area where it was off loaded from shipping truck. Even the cross brace for the hitch roller was bent.
After reading other reviews I kind of expected this however. I can't believe you would ship something like a hitch protecting in the cheap boxes used! You need to improve the packaging!
Other than that it did arrive quickly.
Very good product! Super easy to install. Took me less than 30 minutes to have my 5th wheel hitch set up and ready to pull. Only weighs 80lbs and is easy to take in and out of the bed of the truck. Shipping from etrailer was fast. This is my second purchase from etrailer. Great experience. Company very heart full.
This adapter for towing prep package on Chevrolet trucks was simple to assemble and install and I would recommend to anyone. For me, I did not mate a Curt hitch on the mount and consequently the design of the mount prevents my hitch's sliding feature from working (the slide can not be unlocked). The angle steel which is used to hold the two mounting point halves blocks one of the lock pins. I hardly ever used my slide so I am not concerned.
I'll post back after a 2000 mile haul with the 40 RV. Looks good so far...
Have a great day everyone!
The C16023 worked perfectly with my new Chevrolet silverado LTZ 2500 HD under the bed mounted fith wheel attachment. The only thing I recommend is to read the instruction before installation. It looked so simple to install I went ahead without reading the instruction and had to use a hammer to close the last locking handle. As it turns out there is a simple Castle nut and cotter pin adjustment to make. Luckily I did no damage and all went well during the installation. I would highly recommend this product.
Also etrailer.com was vary helpful over the phone helping me figure out what I needed for my truck.. They also emailed when package was shipped and when it was delivered. They have the best prices as well. A big thanks to there customer service team for all of there help.
Amazing product fit perfect with no issues whats so ever being that this kit is for a none fifth wheel truck option and was able to easily install with no problems, We have owned it over a year and still looks new and works perfect we tow a 44 feet RV very often with no issue and really recommend this product hands down !!!!!
First of all, the purchase procedure was painless and the product performed as listed. I purchased this fifth wheel hitch base for a 2018 GMC 2500HD with under the bed hidden puck fifth wheel configuration. After a few minor adjustments the base fit the truck and the 20K lb. fifth wheel hitch very well and performed equally as well. I would recommend this purchase.
This adapter allowed me to transfer my Curt E16 Roller Hitch from my 2013 GMC 1500 rail-mount to a 2019 Chev 3500HD with OE puck system. It raised the hitch height slightly but was easily readjusted on the E16 hitch body. I also adjusted the pinbox on my 10,000 lb trailer to compensate for the higher overall height of the 3500HD. This is a very well-made product that is working well for me.
I ordered my Curt hitch/adapter rails from etrailer and received a great price and prompt delivery. Everything arrived in good shape and has worked to perfection. Thank you etrailer.
Mostly awesome, just a few nudges and aligning and it was good to go. Took less than 90 minutes to open the box to putting the 5th wheel on the adapter. I also had to over tighten on of the mounting castle nuts to be able to get the cotter pin to go in.
I recently purchased a fifth wheel hitch for my new truck but wasn't sure I ordered the correct one after hitting the "enter" key! I called etrailer the following morning and found out I had, in fact, ordered the wrong hitch. The young man I spoke with was incredibly helpful - he canceled my initial order, explained what I really needed and why and then placed the order. I went on line the next day and found that the order had somehow been cancelled. I then spoke with LEAH G. She is the bomb. She corrected everything and did her best to expedite shipping including personally making certain that MY shipment was on the last truck of the day. What more can I say. Etrailer.com and Leah G are unbelievably awesome from beginning to end! Thank you for a great experience Conrad
Arrived fast works well
The hitch has worked very well. It is very sturdy, and I have had no problems. I would recommend this to someone with a short bed for the ability to slide the hitch.
Installed Curt A20 hitch w/slider rails in 2016 Chevrolet Z71 2500
Very heavy duty hitch. Initially had some concerns so ordered the 20,000 lbs. instead of the 16000. Very good service from the etrailer representatives. Had some concerns on how long the delivery was going to take, however they were able to get it to me in a very short time. Thank you to the individuals who helped with my order. Danny
I didn't want to buy a new hitch, this adapter product worked well for the puck system in my 2019 Silverado.
I had to adjust the hitch so that the fifth wheel trailer was more level when hooked up.
First, the is a very heavy duty hitch. I watch the etrailer videos and the installation was simple. No issues at all. Second, I order from Matt who was very helpful an knowledgeable on the product. He said it would be delivered in two days. I laughed but low and be hold it was delivered in two days and the packing was incredible. I Thank you Matt for all you assistance.
Easy to install and works perfectly!
This was an easy install. Very heavy and ready to pull my trailer!
An excellent experience with etrailer.com

Cammi, my customer support person was awesome. I told her what I needed and she recommended to perfect hitch. I was impressed with her knowledge of their products and how fast it was delivered. Installation was simple as long as you follow the very well written directions.

My hitch is working great still. Easy to use no issues.
I previously owned the Curt A16. We needed a larger tow capacity so we purchased the A20 and decided to buy the S20 slider base as well. Too many sharp turning issues with our 6’8” Chevy standard bed HD3500 during maneuvering. The S20 slider should eliminate this issue. Also I love the design of both the A20 and S20.
