The Curt E16 5th Wheel Hitch with S20 Slider is rated for 16,000 lbs gross towing weight and a 4,000 lbs vertical load limit. Its sturdy, steel construction with a carbide black finish gives a strong, no-nonsense feel when you’re hitched up and on the road. This heavy-duty build provides a solid connection that’s ready for long hauls and big trailers, giving you the confidence to tow securely every time.
Once the king pin slides into place, the auto-locking slide-bar jaw secures it automatically. A rear steel tension bar clamps around the king pin to minimize rattle and movement, creating a quieter, more stable connection. That firm grip means less play between truck and trailer, so you can tow smoothly without the constant clunking or shifting that can wear on both rig and driver.
The dual-pivoting head makes lining up on unlevel ground simple. With 10 degrees of side-to-side movement, the head follows the trailer naturally as you back in, helping the king pin glide into place without binding. The anti-rattle skid plate helps keep things quiet during travel so each hookup feels controlled and consistent.
For those slow turns where clearance matters most, the non-binding S20 slider provides 12 inches of front-to-back travel. Sliding the hitch toward the tailgate gives extra space between cab and trailer at low speeds, reducing worry about contact during sharp turns. The S20 anchors to any industry-standard rails for reliable strength and stability when repositioned.
With four height positions ranging from 14 inches to 17 inches, this setup lets you dial in the right level for your towing setup. That flexibility helps achieve proper bed rail clearance and keeps your trailer running level behind you. The included base rails and installation kit make mounting straightforward so you can get on the road sooner.

Hey guys, this is Jake here with etrailer. Today we're gonna be going over the CURT E16 replacement 5th wheel head. This is designed to replace your E16 5th wheel head. If you've already got one and you're wanting to replace it. If it got damage or if it's old and rusty this is gonna be a perfect fit. It's also gonna come with the replacement bracket.
If you'd like to swap out the head on the S20 which is their new slider base, you can put this in, mount it to the correct height and then put this hitch head right in the top of it. You are gonna get all the replacement parts that initially come with the kit so you'll get new hardware, new pins, a new handle, and this bracket. The best way to get this set up inside the S20 base is to set your head height with the bracket first and then set the head on top of it. Now with our new hardware, we can set the height of our hitch a lot easier than a lot of other hitches out there. A lot of 'em are gonna have to set it with the head attached but this bracket only weighs about 10 pounds so it's really easy to get it in place.
Now to get your new head in place, it's as simple as setting it on top of the bracket. And again, it will come with two new pins. And that's, I think that's kind of nice 'cause when you're replacing you know, new parts you'd like to put new hardware in too 'cause chances are these are gonna be pretty wore out. So some of the reasons why you would need to replace your 5th wheel head is if it's got a lot of rust on it it's gonna start to affect the integrity of the strength of the hitch itself. So if it's got too much rust you might think about replacing it.
If you've not been using enough grease or any grease at all this head can start to score and once it starts scoring you can't really go back 'cause it needs a smooth surface to slide on your kingpin base. Another reason is your grease gets dirty that can cause scoring. If you're not using a lube plate. There's a lot of different reasons of why you would need to replace this head. If your mechanism isn't working correctly anymore.
But it's good to know that you can just replace the head. But with that being said, a lot of people what they'll do is they'll, if they have an A16 or an E16 head and they have the traditional base but they get a new vehicle and they'd like to switch to the slider, you can keep your old head, get the slider, and then later on you can replace the head. So there's several different options and reasons of why you would need a new E16 head. Well, with all that being said, we've got it all installed it's ready to go, and it's ready for our next trip.
Ratings & Reviews
Deliver was on time, arrived in good condition, all material ordered seems to be complete and in place.
I would give it a 3 star review. The product itself was perfect. The package arrived in tact, but 2 parts were missing. Upon contacting you, I was told they would send out replacements. I was hoping they would overnight them since I had an appointment 2 days later for the installation of the 5th wheel rails. But they were sent standard usps mail. So I had to cancel the appointment. I ended up installing them myself, which took more than 6 hours, which the directions said 1 1/2 hours for a novice. Also, the measurements on the directions said 28 15/16" from the tailgate to the front edge of the rear rail. I drilled the pilot hole, and it wasn't even close. It ended up being 28 1/2" and I even have spray in bedliner. So I have mixed emotions about the purchase. They are installed, and seem very sturdy.
Great install! Had no issue with the installation of this unit. Directions were easy to follow. Great product and will be trying it out real soon 3975CK Crossroad Cameo 5th wheel!
E-trailer has detailed instructions and videos for anyone to install there on hitch.
The hitch looks strong enough but the installation was difficult for a man over 65 with big hands installed on my 2021 Chevy 2500.there were some very hard to get at places to get spacers and nuts on bolts took me 6 hours by myself probably would have been quicker and easier with two people.haven’t tried it yet will let you know how well it works.
No directions, but I’ve mailed them for directions. Fast! Excellent looking and heavy duty appearing parts with a hardware kit included! Excellent! Now let’s get some directions and get it put in.
The hole in frame that was supposed to line up with was about a 1/2" toward the back of the bed using the 28and 15/16" plus the liner on the instructions to the bed frame. I moved it back. Using the 1/8" to see where you will be is how I figured it out. Good idea.
I wanted to have the full side brackets (just my own insecurities) and didn't want to drill the frame. Instructions were good.
EVERYTHING LOOKS GOOD AND CAME IN A TIMELY MANOR. VERY RESPONSIVE RO CHAT MESSAGE
The time for install on the instructions is way off 40 min (professional) 80 min (DIY) I installed this kit on a 2025 3500 silverado long bed. It also has the factory overload springs whis also contributed to some of the issue. The left front cross rail bolts are on top of the fuel tank so it's a bit tight. The right side bolts are between the heat shield for the exhaust and the bed. I had to remove the shield to get access to the cross rail nuts. The U bolt was another issue as they were about 1/2" to long and would contact the springs when loaded. The last thing is I was shorted 1 carige bolt. Out side of that it's inatalled and seems to work as designed.
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.
Fit perfect. Easy install if you’re han dy.
Put it in my self went great towed camper home today!
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.
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.
Easy to install and it works great.
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!
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.
This kit fit well and the installation instructions were very clear and easy to follow.
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.
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.
