Secure, Interlocking Two-Piece Jaw

A16 Two-Piece Interlocking Jaw

Unlike slide-bar models, the rounded, interlocking, two-piece jaw on this fifth-wheel trailer hitch inhibits rattle and movement by securely wrapping around your trailer's king pin, resulting in easier hookup and a safer, quieter ride.


Three-Point Indicator System

A16 Color Indicator System

Get peace of mind with Curt's color-coded lock indicator. Just look at the indicator - either the one on the handle or the one on the hitch itself - to determine whether the jaw is in the correct position to uncouple (red), couple (yellow) or tow (green).


R16 Slider

Most often used on trucks with 6' and 6-1/2' beds, this roller helps to eliminate clearance problems during slow-speed turns. When you are towing a fifth-wheel trailer, your hitch must be situated on the cab side of your truck's rear axle. However, at slow speeds you can use a roller to slide the fifth-wheel hitch (and the trailer) toward your truck's tailgate and past the rear axle, creating enough space between the cab of your truck and the trailer to permit less-restricted turning.


Non-Binding Design

The round-tube design of this slider allows for relatively uninhibited movement of your fifth-wheel hitch. Because your hitch can glide smoothly and easily along the rods, there is less chance of binding.


With straight, flat contact points, as found with square-tube sliders, tension can build between the slider and the hitch when your truck and trailer are somewhat out of line or are on uneven ground. As a result, it can be difficult to properly activate the slider when your truck and trailer are not in a straight line.


With a round-tube slider, there is more give between the contacting surfaces, allowing better mobility of the hitch system. Fewer corners means less tension buildup. Activating a round-tube slider is easier, and operation as a whole is smoother.


Curt rebranded this fifth-wheel trailer hitch by changing its name from Q16 to A16 in 2016. All features and specifications remained the same.

Like some other posts, followed instructions to the letter and hitch would not drop into rails. Loosened all the rails bolts, mounted hitch, and re-torqued everything. Puck mounting brackets were just off square a bit and twisted the rails when first installed. Either square ‘em up or alter instructions so it goes in first time. Installed in a 2022 Silverado 2500 6’10” bed. Loved the plan, set the rails first time in a few minutes (instead of waiting in a shop for four hours while someone else did the boring and cutting and such). Hitch has been in two other trucks with conventional rails and always fit. Coulda been a five star, but I am familiar with Curt and feel sure they will get it right.

Still satisfied, still recommend. Easy to move hitch in truck as one unit when I need more of the bed available, no further adjustments needed.

The Curt A16 5th wheel w/ R16 slider is a great looking hitch. I received the hitch on May 11, 2023, replacing an older Reese 15K hitch with a slider lock bar. It was easy to finish the assembly and install. I immediately took my fifth wheel out, using the new hitch with the dual jaw locking system. The ride was amazing. The RV, which weighs approximately 10,000 pounds, loaded, did not buck or rattle, and responded perfectly to the turns, acceleration and deceleration with no issue. It was if there was nothing behind me.
The only issue with the Curt A16 is the height. At its lowest setting, the nose of the trailer was up too high. However, by raising the tongue of the RV to its highest setting, I was able to remedy most of that issue. I am looking forward to my trips this year with the new hitch!

Great product. Bought a new F250 with puck system and this product adapted my hitch to the puck system. I did have to drop the head of my hitch because the adapter raises it 2.5 inches. Feet on my Curt A16 fit right into the rails on adapter.

Still doing a great job. I have an overhead hoist in my garage so I can remove adapter and hitch as one unit leaving me with a clean bed. unit into pucks in bed and turn four handles and we’re ready to go! Great product.

@Ron Hoists are lifesavers!


by: Floyd03/16/2024

Really wanted to give this 5 stars but it appears they didn’t try it with a hitch like mine. The flanges on the cross supports do not allow my hitch to seat down onto the support tubes. Thus the hitch holes will not line up with the tube holes and the pins cannot be inserted. I fixed it by taking a sledge hammer to the ears on my hitch until the holes aligned. I shouldn’t need to do that to something this expensive.

It is a shame that you had to use a sledgehammer to use the rails. I wanted to ask which brand of hitch do you have?



by: Paul04/25/2024

So far it works great. Only pulled in a short distance and backed it up into my driveway. Make sure you have help lifting this. Very Very heavy. Directions were average but got the job done. Love the extra turning radius on my short bed F250. Make sure all the parts are there. The handle to release the king pin off the hitch was not in the packaging. The box that the hitch and slide came in were all in tacked and looked good. Emailed etrailer and within a few hours they sent were processing the order for the handle. Arrived in 2 days. That's great customer service.

After purchasing a new truck, I needed an adapter for the Chevy puck system without buying the entire 5th wheel hitch, this fit the bill. Heavily built and easy to install. The only thing I would recommend is to use larger cotter pins because the ones that came with assembly would not engage the castle nuts.



by: Brian03/12/2024
2020 GMC Sierra 3500

Assembly and setup was super easy and quick. Seems super stout. I was worried the added 2 1/2 inches of height added by this would require some adjustments to the pin box. However once hooking up my trailer, no adjustments were necessary. Trailer is almost spot on level, and I am still maintaining 6.5-7 inches of bed side clearance to the trailer.

This is definitely a quality part. I've had it a year, easy to swap between my fifth wheel and gooseneck plate. It installs or comes out easily, it fits securely in my 2023 Silverado 3500. I've pull all of the 25000lbs it's rated for without issue. I highly recommend it. It allowed me to use my fifth wheel and gooseneck plate from my old truck that had rails in it.



by: Gilberto03/27/2024

Looks like a received a returned hitch. All my hardware is missing. And still waiting on one box. The sliding rails. Starting off to a bad start.



by: James 03/21/2023

Easy assembly, fit well. Works just like it should. Put the hitch at a good level to level 5th wheel.

Good as the day I installed it



by: Warner03/25/2023

Frist order was wrong. Not a happy camper as I was not able to bring my new fifth wheel home the day of purchase. Talked with Joshua at etrailer, he helped me with a new order, it arrived two days earlier than expected. Assemble was easy. waiting to bring new fifth wheel home. Thanks Joshua



by: Kevin L 09/14/2016

First off I just got done installing the hitch and I hooked on my 35ft fith wheel trailer and went for a ride with windows down sun roof open and not a single rattle , clank , or noise from the bed of the truck with this hitch . It was easy to assemble but I did have one spot where the paint got chipped on the slider during shipping so I just touched it up . Very satisfied with hitch it latches automatically when you back in to it and the slider part works like it should .



by: Kevin06/06/2022

Upgraded from TT to fifth wheel. Once I learned the basic operation I have had mo problems with this hitch. Rides a little high because of adapter for factory puck adaptor but still fits my tonneau cover which I also bought from etrailer.



by: Gwen 05/08/2024

Very happy with this hitch. Installed it myself with the installation instructions and trailer videos. Mush easier to operate than my old hitch.

GMC

I purchased a new GMC and didn't want the rails in the bed of my pickup. This worked great with the 5th wheel hitch that I had.



by: Ron C05/15/2017

The Curt system is really high quality. No issues at all putting the system in. One thing I do like is the position of the plate handle. It does not stick upward and is even with the plate. By designing the handle that way I can still cover my bed with my tonneau cover where other manufactures the handle was higher than the bed rail. The price was excellent and dealing with customer service was the same.



by: Daimon C. 06/25/2019

Great product. Easy to assemble and fits perfectly in standard bed rails on 22” center. I have coupled up with it but have not towed with it yet. Have a short trip of about 400 miles coming up in about 2 weeks. So far I am very happy with the way it couples and slides. Unlike my old square tube slider this one is very smooth and the price was right . Ordered late afternoon on Thursday and it delivered on Monday. Great shipping time. I like everything about it especially the fact that when you uncouple it is automatically set to recouple.

Fit right in my 2020 GMC Sierra and my Reese 16k 5th Wheel for directly on that with 4 pins.



by: Thomas 04/05/2023

Very easy install just as described allows me to use same fifth wheel in multiple vehicles.

It has been around a year since my purchase I haven’t had any problems. I’ve only had to remove the hitch once because I needed the full bed of the truck. I was able to assemble it back in the truck just as easy as the first time. The main reason for this purchase was it saved me from having to purchase another hitch and I can remove the hitch and use it in my other truck with standard rails.



by: Jody12/30/2022

Way to go etrailer, my order was received and with in two days my new adapter base for my new truck came in great condition and i installed in less than 15 minutes along with the spider insert I had from my previous purchase it fit like a glove Thank you for a great easy web site with all the info one needs to get the right product your company that has never let me down in my three orders that I’ve made

Ford F-350 Super Duty

Work great on my 2023 ford f350. And 38 ft 5th wheel very smooth when driving. Easy to hook up 5th wheel



by: Jared08/08/2022

Great hitch and great value. Our trailer is 2000lbs on the hitch and 12000lbs loaded, so not a huge rig. My favorite feature on this hitch is the locking jaw system, it makes coupling and un-coupling very smooth. The slider (when rarely used) is very smooth as well. Most of our towing is in the Colorado mountains and I feel very safe using this hitch. Lastly, I know this is just aesthetics, but it's a nice looking hitch.

Ram 3500

Received today and it was packaged very well. Install took about 20 minutes taking my time. I have not hooked up to my trailer yet but this mount is very stout and fit my 2024 Chevy 3500 HD perfect!



by: Mary07/07/2022
2022 Ford F-350 Super Duty

The holes didn’t line up had to Grid to make bigger and took out the rubber shims. When I watched the video it said the hitch rails would be 2 inches higher than the bed it is 4 inches

I reached out to the manufacturer and they said their product page says the height should be around 2.5 inches. It sounds like your bars were installed upside down or backwards.



by: Robert 09/06/2022

Super easy to build, locks in place. Towed my 310bh fifth wheel over 4,000 miles on it!!
