Received these in record time...Thanks
installed. I replaced the R16 slider rails. As it turns out I never used them in the slide position. Installing the Base Legs eliminated a good amount of weight making it much easier to handle. It also gave me more room in the bed.
I did have to file a little on the feet and rails as it fit slightly different. Just a little adjustment though.
Big improvement and etrailer came through with fast shipping.
Thanks John F


I had a slider hitch with the Curt A16 head. I replaced the slider with these legs since my 5th wheel is equipped with a Turning Point pin. Perfect fit on my 2012 Ram 2500 !!



Still working great after a year and 10,000 miles towing with it


The A16 Slider hitch mounted on 2018 ram puck frame was too tall for my new ram 4500 flat bed, I installed the A16 fixed legs to the A16 slider head mounted it to a curt gooseneck adapter plate, it made a significant drop in the height of the hitch. Thanks etrailer for providing multiple options for various hitch challenges.



I used these legs to convert a slider hitch that was mount on a ram puck system to a fixed hitch mounted on a flat bed truck to make a long haul across country. Worked great


these legs were an exact fit for my fifth wheel hitch. I have used them several times and they solid .


I ordered these to lower my reciever in the bed of my truck. Originally I had a slider hitch when I owned my 2012 Ram but found that when I changed to my 2016 Ram with a Rambox I needed to go to a Sidewinder turret on my 5th wheel. The combo of the Sidewinder and slider hitch putched the front of my 5th wheel too much for my comfort. These fixed legs were the perfect solution. Etrailer got them to me quickly!


This product worked exactly as advertised. The etrailer team of customer service reps have always gone out of their way to provide the best service possible.


I replaced a R16 roller assembly with the Q16 leg assembly because I no longer needed a roller hitch. Everything bolted right up with no problems. The hitch height adjustment on the roller was a low as it could go for my setup, on the leg assembly the hitch height adjustment was in the middle position for the same hitch height. The leg assembly is probably about 100 pounds lighter than the roller assembly. Removal and installation of the hitch is now much easier. As always, customer support at e-Trailer was great.


This company put together my order the same afternoon I purchased it and it was at my house in record time!
Thank you Etrailer


I would like to thank etrailer for the outstanding service. Your tracking system is outstanding, fREE SHIPPING, it took less the 36 hours from when I ordered it to show up on my door in DETROIT. The next time I need something you will have my order. THANKS FOR ALL YOUR HELP.


The C16920 legs matched up very nicely to my C16515 Head Unit. I found I no longer needed the original slide mount and these legs are much lighter, making removal and installation much easier.


Outside box had some damage on delivery, but arrived super fast. No damage to the product. Great price and product.


Part was exactly what I needed. Fast shipping and Great service. Thanks etrailer....


The item was very to install and works perfect. Thanks Tim ! great job..

  • How Far Apart Do the Rails Need To Be To Install the Curt A16 5th Wheel Hitch
    In order to install the Curt A16 5th Wheel Trailer Hitch part # C16120 you'll need to position the base rails 22" apart on center. That is the distance between the center of the legs front to back. I have attached a photo with the dimensions of the above bed base rails that will fit the Curt A16. The correct base rails are the Curt Universal Fifth Wheel Base Rails part # C16204.

  • Parts Needed To Use Curt A16 5th Wheel Hitch In 2019 Ford F-250 XLT without Factory Puck System
    If the 2019 Ford F-250 XLT does not have the OEM Pucks, then they can still use their old Curt A16 5th wheel hitch as long as it is for ISR (Industry Standard Rails), they'll just need to install rails in the bed. If they don't have and ISR hitch they can replace the legs with # C16920 to convert it to ISR. I'd go with the Curt Installation Rails # C79BR. These are custom fit for the truck so install will be pretty quick compared to the cheapy universal kits, and will work perfectly with...

    In regards to a Curt 5th Wheel Hitch, the weight capacity comes from the head not the base so in order to upgrade from a Curt A16 Hitch like part # C16521 to a Curt A20 or Curt A25 Slider you'd a new head, the Curt A20 Head part # C16540 or the Curt A25 Head part # C16580. These will both work with the base for a Curt A16 Hitch. Please note, the base does max out at 24,000 lbs.

  • Replacement Legs to Convert Curt A16 5th Wheel Trailer Hitch Slider to be a Stationary Hitch
    Technically, you can still use the slider and just keep it locked in the forward position since you'll have a long bed. If you prefer to convert the slider of your Curt A16 5th Wheel Trailer Hitch # C16521 use # C16920 for the legs. If the old Ford F-250 and new Ford F-350 are both model year 2006 then you can use the same rail kit # C16448-204. If they're different let me know the year of the new truck and I'll be happy to suggest the correct custom install kit.

  • Can A Curt Fixed 5th Wheel Hitch Be Used On a 2020 GMC Sierra 2500
    It is possible to use a fixed fifth wheel hitch on a 2020 GMC Sierra 2500 but it all comes down to the trailer. If you were using the same trailer on another short bed truck without issue the odds are you will be fine with a fixed fifth wheel hitch. I recommend the Curt A16 5th Wheel Trailer Hitch because of the dual jaw design which is very secure and works well to reduce chucking/jarring and the easy to remove head with only one pin. If you have the factory prep package then you need...
