The Curt A20 5th Wheel Trailer Hitch is built from sturdy steel and rated for 20,000 lbs gross towing weight with a 5,000 lbs tongue weight. It’s made to handle large fifth-wheel trailers with stability and strength while keeping everything locked-in tight. The durable carbide powder coat finish helps protect against wear over the long haul so it stays reliable trip after trip.
A fully articulating torsion head gives you smooth, stable towing even when the road gets rough. It lets the hitch pivot naturally to control coupling and suppress road shock, cutting down on the clanking and jerking that can wear you out on long drives. The result is a quieter, more relaxed ride whether you’re cruising straight or pulling through uneven ground.
Before you tow, a quick look at Curt’s color-coded indicator tells you exactly what’s happening—red means uncoupled, yellow means ready to couple, and green means it’s locked and ready for the road. You can see the indicator right from the cab or beside the truck bed, so there’s no guessing or second-guessing your connection.
The interlocking two-piece jaw design provides 360-degree contact around the king pin. That tight wrap cuts down on movement and rattle compared to slide-bar setups and gives you a more secure feel when you ease forward or brake. It’s one of those details that makes every hookup feel solid from the first mile out.
When it’s time to open up your bed space, a fast 1-pin head removal makes it simple for one person to take off the hitch without special tools. The included plastic lube plate also keeps hookups smooth so you can attach or remove without fighting friction. Height adjusts from 13" to 17", giving some flexibility for a level setup while staying quick to handle when stored away.
This fifth-wheel hitch is compatible with rotating pin boxes, such as the first generation Reese Sidewinder, Reese Revolution, and 5th Airborne Sidewinder, only when used with a wedge (sold separately).

Today we're going to take a look at the Curt A20 dual-jaw fifth wheel trailer hitch with a 20,000 pound weight capacity. Now, this fifth wheel hitch will mount in your truck bed so that you can tow your fifth wheel trailer. It uses the interlocking two-jaw system right here, which provides a nice 360-degree jaw-to-kingpin contact, and because of that it'll give you less rattle, more security than your slide bar models. Also, on the front of each jaw, over here and over here, you can notice there's two built-in grease zerk fittings, which will give you easy lubrication of the jaws. This hitch does use a fully articulating torsion head for controlled coupling and a nice stable, quiet ride. It will self-align for easy hookup, and helps suppress road shock to reduce any bothersome towing noise. The handle right here is a lockable handle.
It's a very short-throw single-handle operation. The nice thing about it, also, it does self-reset to the ready-to-couple position after uncoupling. Now, when you put this together, when you mount the crossmember to the legs, there's three rows of holes on the crossmember, so it actually will give you a four inch hitch height adjustment. The hitch height would be measured from your truck bed to the top of the hitch head, and you want that to be as close as possible, so when you're towing your fifth wheel with your tow vehicle, you want those level. It gives you three choices, anywhere from thirteen inches of hitch height adjustment up to seventeen inches. One of the nice features on this is the three-point indicator system. It'll tell you what position the jaws are in.
What's nice about it is that it's color-coded. Let me just swing this around so you can be able to see. If you notice, right under the hitch head, right here, you'll notice right now it's showing solid green. That means the jaws are completely closed. If we had a kingpin in there, the green would mean you're ready to tow.
This color coding will tell you if the hitch is ready to uncouple, couple, or tow. What's nice about those colors and looking, if you're in the cab, the cab would be right here, you can turn around as you're hooking up or uncoupling and watch the color, and when it changes, it tells you the position of the jaws. Basically, the green, like it is now, the jaws are locked closed; it's safe to tow. If it goes to yellow, let me just unhook this and pull out the handle. You can see right now, because I opened the jaws, it's showing yellow. Yellow means the jaws are ready to couple.
It's safe to back in the truck to couple up to your fifth wheel. It if would show red there, that means the jaws are locked open, and it's safe to pull your truck away. When it's red, you do not want to couple. Also, this has a nice fast one-pin head removal, makes it very easy for one person to remove the hitch. Back here, there's a clip you can pull out, and then you can pull this large pin out, and that'll allow you to take the head out of the crossmember so you can take it apart in pieces, which makes it easy for one person to remove the hitch. Also included with this . Let me roll this around here. There we go. Included with this, I have laid out, comes with the plastic loop plate right here. This plastic loop plate will go onto your kingpin and lets the kingpin glide smoothly into the hitch during hookup. Also comes with, you can see, the pins and clips for attaching the legs to your base rails. This is a simple installation with base rails and an installation kit. Now, the base rails and the installation kit we do sell separately on our website. I would recommend to go to our website, use our fit guide, put in your year and model vehicle, and it'll show you the correct base rails and installation kit for your application. This fifth wheel hitch is compatible with B and W, Curt, Demco, Draw-Tite, Hidden Hitch, Husky, Reese, and Valley above-bed base rails. This is a sturdy steel construction with a durable carbide powder-coat finish. Again, the specs on this. The gross towing weight capacity is 20,000 pounds. The vertical load limit or pin weight capacity is 5,000 pounds. We had mentioned the hitch height adjustment from thirteen inches to seventeen inches. What I'm going to do now is, we already have the jaws open, ready to couple, showing yellow, so what I want to do is here's an example. This is what a kingpin would look like on your fifth wheel. When you go to hook up, your kingpin would slide in between the two jaws, just like this, and once you get it far enough, your jaws will completely wrap around the kingpin. You notice the handle automatically slides up. The holes line up, so you just take your pin and clip, drop your pin into the hole, clip it, and that'll lock the handle. Now, the hole is large enough, you could actually put a padlock on there if you wanted extra security. It does come with this attached pin and clip. With the handle locked, you look back here at the color, it's showing green. That means you're all ready to tow. Again, to uncouple, you just pull your pin out, open it back out, and go, be able to back right out. That should do it for the review on the Curt A20 dual-jaw fifth wheel trailer hitch with the 20,000 pound weight capacity.
Ratings & Reviews
Overall a great hitch. Couple of minor scratches. Like the easy disassembly to be able to install/remove from truck alone.
Love it. Easy to take apart and move! The instructions were very clear on how to assemble. I pull a 43ft camper and have yet to have any problems! Well worth the $$
Works fine
Easy to install with Basic tools .
Works well with my new hitch, Installation was not the easiest in the corner on the driver side closest to the cab due to the truck fuel tank.
Worked really well. Especially like the one piece mounting bracket. Secure and easy installation.
I ordered this to install in my 2020 Silverado 2500. The install was easy and took close to 2 hours. Have not pulled my fifth wheel yet so really no idea how this will hold up. Everything was in the box nothing missing. Shipping took 2 days to get to my house. Very happy so far with everything I have ordered fro you.
Very nice piece!Arrived sooner than expected. I have the A16 version,that I used for a 10k Lbs 5th wheel and that handle very well but now I'll be towing a 16k tow hauler so I know this a20 will do just fine. And I love the locking jaw versions. I feel these are most secured in any type of towing.
I installed myself on my 21 GMC Sierra 2500HD, Denali, Duramax. Took me around 3hrs to do with basic shop tools. Over all the unit itself is very nice. Heavy well treated metal, bolts are all good quality. Not one single alignment issue. Sucks that the truck manufacturers can’t make some sort of pre setup locations as it was some tight finger tip spots. But that’s not to the fault of This item at all.
Excellent hitch, took two of us 10 minutes, during a rain storm lol, to put together and install! As far as towing our Redwood 5th wheel it performed flawlessly, easy to hook up and the ride was super smooth and no noticeable bucking!
Fit perfect. Easy install if you’re han dy.
Put it in my self went great towed camper home today!
Easy to install and it works great.
Installed these bed rails on my 2020 Silverado Duramax 2500HD. Heavy duty rails and of good quality. Install time was around 3 hours. Definitely remove spare tire and heat shield. I did find it very difficult to torque 2 of the nuts on the driver's side front rail. Everything else no problem. I did spray some undercoating on the frame rail ends and nuts. Just did that for extra protection and it will make it easier to see if there is any movement when towing.
I already had a curt goose neck frame mounted in truck so I used the Curt adopter plate # 16220 an the A 20 curt 5 wheel hitch assembly was very easy with no issues looking forward to putting it to work with my G M C 3500 also purchased a curt bumper dual ball adjustable hitch
I purchased this rail kit for a camper we bought. It’s fits perfectly with the hitch that came with the camper. I also bought the spider gooseneck adapter which works great with these rails!
Hitch slid into existing rails after a very minor adjustment. Took my son and I about 25 minutes to assemble, torgue bolts and adjust rails in the bed of my truck. we have used it twice already and camper did not bang and pop like it did on old worn out receiver.
The ordering process was also very smooth. Kelsey took the time to explain the differences in the hitches before I made my decision!
I Would recommend both etrailer and this hitch if you are looking to change out!
Hitch came packed well even though the box looked banged up. Everything was still undamaged and in good usable condition, just minor scuffs. I think this unit will have more when I get done with it. Watched a you tube video from curt on installation and had little trouble installing the hitch following the enclosed guidelines. Everything lined up according to plan. I think the hardest part was getting access by the heat shield. Tough spot to work on but I had help from a younger, more adapt helper who was able to manage just fine. A creeper for underneath was super handy and a 6 foot ladder to climb in and out of the bed made it a whole lot easier. Really did not need to use a lift. Would have made it a bit harder to work in the bed. My truck is quite high which allowed nice working space underneath.
5 stars for the quality of the parts. Directions get you through but could be better. Video of installation makes it look way easier than it is. Took me 2 afternoons to complete the process.
This kit fit well and the installation instructions were very clear and easy to follow.
From start to finish the experience was very enjoyable. The customer service team was amazing and everything happened just as promised.
The same hitch at my local trailer store cost much more.
Would definitely recommend etrailer to anyone.
I have towed with the Curt A20 for a few thousand miles. I really like this hitch. The visual hooked versus unkooked indicator is awesome. It operates flawlessly. I do get some chucking over bridge expansion joints. However, it seems like most people have this problem. On normal roads it pulls great.
Installed on a 2021 GMC Denali DRW. The installation instructions and video need to be updated they are somewhat miss leading as to the difficulties of install. The driver side front rail nuts are almost Impossible to install because of gas tank. They will be impossible to torque without dropping the gas tank. Your will also have to remove the dual rear wheels to torque the frame plates Took almost 5 hours to install. Other than that have yet to use hitch.
Product itself is really nice, well engineered and extremely stable in the truck bed. It's not as scratch resistant as I had hoped, I moved an electric oven and it really scraped the rails.
It does hold the hitch in place perfectly while towing, the holes and pin placement slots are spot on exactly like they should be. Mates really well with my Curt Fifth Wheel Hitch. Overall, satisfied with my hitch rails.
The only drawback is the installation.... OMGH! Was going okay until we got to the bolt that's on top of the fuel tank, could barely reach it and only get one millimeter turn at a time, then the torque wrench got stuck....
Just an ass-kicker!
But perseverance pays off and we got it installed and torqued to proper settings. Hope I never have to do that again.
Very easy to use! It was a job to install though by myself!
If you don’t have plenty of of time wait until you do!
I had to drill holes in my brand new truck bed so I measured and measured over and over lol! Note: if when your unhooking trailer from it and the jaws do not open it’s no problem. When you try to pull away they will open right up no issues ! Don’t really know why they sometimes do not open when I disengage the handle do not open themselves! Great product though no other issues with it!
