This hitch was very easy to install. It did come missing one of the bolts to attach the head to the base. I contacted George at etrailer customer service and he sent the replacement bolt out ASAP and I got it in just a couple of days. Got the hitch completely installed and it seems to operate just fine. Haven't towed with it yet but it functions fine. I highly recommend etrailer.com for their outstanding customer service.

Ask the Experts about this Curt Accessories and Parts

  • Which Hitch for Ram Factory Puck Mount is Compatible with a Sidewinder Pin Box
    I may have a solution for you on this, but the Mopar hitch for the Ram OEM pucks is not compatible with a Sidewinder style pin box; it's really just a re-branded Curt Q20 head # C16530 so the spherical axial bearing that it has won't work with a rotating pin box. For this reason you'll need a hitch like the Curt A20 5th Wheel Trailer Hitch for Ram Towing Prep Package - Dual Jaw - 20,000 lbs # C16044, which is compatible with the Sidewinder pin box's rotating. If you just want the hitch...

  • Hitch Cover Recommendation for Curt A20 Fifth Wheel Hitch
    I suggest the 24 by 24 by 18 inch Classic Accessories Fifth Wheel Hitch Cover # CA80116. This will fit nicely on your Curt A20 # C16140. I've attached a picture of the cover on a Q20 so you can get an idea as to how it looks.

  • Is There a Curt A-20 5th Wheel Sliding Hitch for Ford Factory Prep Package
    Yes, in order to obtain the Curt A-20 5th Wheel Sliding Hitch for Ford you just need part # C16540 and part # C16020 which is the exact same as the part 16676 that you referenced. If you were to order 16676, it would still come in two separate boxes which is part # C16540 and part # C16020.

  • How To Upgrade from a Curt A16 to A20/A25 5th Wheel Hitch
    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 to a Curt A20 or Curt A25 you'd need 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.

  • Dimensions of the Curt A20 5th Wheel Trailer Hitch Head Part # C16540
    I went out to our warehouse and measured the Replacement Head Unit for Curt A20 5th Wheel Trailer Hitch part # C16540 for you. The base of the unit is 18" wide and the bolt holes are spaced 4" apart top to bottom on center. I have attached a few photos showing both of these measurements for you as well.

  • What Bolt/Size Do I Need to Attach My Curt A20 Hitch # C16540 To My Slider Base for Standard Rails?
    I went ahead and confirmed with my contact at Curt that the hardware that you need for attaching your Curt Replacement Head Unit for Curt A20 5th Wheel Trailer Hitch # C16540 to your 20k roller base are standard bolts (not Curt specific) that are 14mm x 2 mm per thread and 45mm long. If you need a set, Curt sells them. The bolts are the Replacement Head Mounting Hardware for Curt 5th Wheel Slider Hitches # C35UR. This set of 4 is all the bolts you need for the installation.

  • Curt A20 5th Wheel Hitch for 2020 GMC Sierra 2500
    If you were to purchase the Curt # C16540 A20 5th wheel hitch head/center section plus the # C16024 legs for the 2020 GM fifth wheel prep package, you would indeed have a complete hitch with everything necessary included. If you wanted to install a 7-way in your truck bed, you'd need part # 20110. I've linked to a video showing a typical installation of the # 20110.

  • Does Curt A20 Fifth Wheel Hich Only Need New Legs to go From GM Truck to 2018 Ford F-250?
    You are correct that with the Curt A20 fifth wheel hitch, the head unit # C16540 only needs hitch legs # C16017 to be used in a 2018 Ford F-250 with the puck system.

  • Difference Between # CU53FR and # C16024 Curt 5th Wheel Trailer Hitch Legs for 2020 GM Puck System
    The Curt # C16024 fifth wheel legs you mentioned fit the A series hitches from 20k and up; the A20 # C16540, A25 # C16580, and A30 # C16590. They're technically designed for the A30 because of the legs's 30,000 pound rating but they still fit the other two. With that in mind they will not, however, increase the weight capacity of the other 2 hitches. The # CU53FR legs fit all of the same hitches plus the Q Series and E Series hitches as well. These legs even fit the A30 however they...

  • Best Sliding 5th Wheel Hitch for 2019 Ford F-250 Super Duty With Ford Factory Prep Package
    You mentioned wanting a light slider, though I do have to say that all 5th wheel hitches are going to have some heft to them. That said, there are ways to make it more manageable to remove them from the bed, which you can do by removing the head unit first and then the base, though it will still take two people to remove. Having said that, I will give you a couple options, starting with what is absolutely the best sliding 5th wheel hitch for your 2019 Ford F-250 with the factory Ford...

  • Can Curt A16 Head Replace Curt M20 for 2017 Ram With Puck System, and Sidewinder for Lippert 1116
    Okay, there's quite a bit to unpack here so to make things easier I am going to take your questions one at a time. 1) Your Ram OEM M20 hitch is the same as the Curt Q20 Curt Q20 5th Wheel Trailer Hitch # C16530-16021; it uses the same legs so you can replace the head with the Replacement Head Unit for Curt A20 # C16540 or the Replacement Head Unit for Curt A16 # C16520. 2) The Sidewinder Wedge Kit for Curt A16 Fifth Wheel Trailer Hitch # RP31016 is correct for the A16 or you can...

    If you are trying to remove the head from the center section on the Curt Q20 5th Wheel Trailer Hitch w/ R20 Slider part # C16530-16020 then you will need to remove a pin, clip and cap from each side as you can see in the attached photo. If you have already done this then most likely you will just need to use more force in order to do so as they can be rather hard to remove. If you will be frequently removing the head then the Curt A20 5th Wheel Trailer Hitch part # C16540 would have...

    The 2020 GM rail kit actually changed from 2019 so the leg kit you'd need for your 2020 Chevy Silverado is the part # C16024 but it will allow you to do what you are wanting to do by connecting your A20 head # C16540 to it to give you a complete hitch.

    The Curt OEM 5th Wheel Hitch Legs for Chevy/GMC Towing Prep Package part # C16024 is designed to replace the legs of the Curt A20 # C16540, Curt A25 # C16580 and Curt A30 hitches to adapt the hitch to the 2020 and newer Chevy/GMC trucks with factory-installed, underbed towing prep package. The legs will not fit the A16 hitch head or center part. Instead you need # CU53FR for for the A16 in your truck.

  • Can the Curt E16 Head Be Swapped Out for the Curt A16/A20 Head
    Yes, the Curt E16 Hitch Head can be swapped out for the Curt A-Series or Q-Series. The A-Series is the new design and what I recommend using. It has a more secure locking jaw system than the Q-Series among a few other things. I recommend using part # C16520 or if you want to upgrade capacity, part # C16540 for 20,000 lbs.

    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.

  • Is Premature Wear An Issue with the Curt Q20 5th Wheel Trailer Hitch
    I have personally not heard of anyone having the same issues you are with the Curt Q20 5th Wheel Trailer Hitch after such a short amount of time. I even searched though some of our reviews and also was not able to find any other instances of said issue. That said, if you purchased this hitch from us then I will see what we can do to go about getting you a warranty replacement. If Curt stated they would not warranty the hitch due to what they said was caused by overloading then options are...

    The Curt fifth wheel slider part # C16020 does fit the factory rail kit of your 2020 Ford F-350 and it weighs 170 lbs. The A25 head part # C16580 would then be a really great option and would easily tow your trailer. The head weighs 97 lbs. The A20 head part # C16540 is actually listed as weighing more at 104 lbs.

  • Curt GM Leg Kit for Curt A16 Hitch on 2020 Silverado 2500
    The Curt A16 hitch heads # C16520 are narrower and have a different bolt pattern, so the correct GM leg kit to use is part # CU53FR. The GM leg kit part # C16024 is designed to fit the 20K and up Curt heads. Like the A20 hitch head # C16540.

  • Is Curt Q20 Head Compatible With Curt A20 Legs
    I checked with Curt for you, and the head unit of the Curt Q20 is not compatible with the legs of the Curt A20 as they mount differently. So what you would need instead is the head unit of the A20, which is the Replacement Head Unit for Curt A20 5th Wheel Trailer Hitch # C16540. I have added a link below to a video review for you to check out as well if you'd like to take a look.

  • Why is Reese Sidewinder Pin Box Not Compatible with Curt Q Series Hitch?
    The rotating pin boxes like the Sidewinder Fifth Wheel King Pin with Rotating Turret by 5th Airborne, 16K # ST400-5AS16K are not compatible with the Curt Q series hitches because of the hitch head design that had a unique spherical axial bearing. That system allowed too much movement for any of the rotating pin boxes to be compatible. If you already have a Q series hitch, I recommend simply changing the head of the hitch with the Curt A series 16K # C16520 or 20K # C16540. Either...

    If you are currently using the Head Unit for Curt E16 Fifth Wheel Trailer Hitch # C16515 with the Curt R20 Round Tube Slider # C16550 then yes, that is compatible with the Adapter Rails # C16023 which fits the OEM Pcuk System on your 2019 Chevy Silverado 3500HD. Please keep in mind that your weight rating is limited by your lowest rated component. So even though the adapter and the R20 slider are rated for 20K, the E16 is only rated for 16K so that is what you are limited to. If you'd...

  • Can the Slide Base On a Reese Elite 5th Wheel Hitch Be Replaced
    I do have an option for you but the Reese Elite Series Slider Base part RP30070 as you have come to find out is no longer available through the manufacturer or other vendors such as ourselves. That said, the cost of replacing this base if it were even available is going to be about the same as a new 5th wheel hitch so that should lighten the blow a bit. This is also an excellent time to upgrade. I recommend the Curt 5th Wheel Round Tube Slider Base part # C16020 with the Head Unit for...
