works great

Finally received the correct products to install the 5th wheel hitch in my new 2020 Silverado HD. It went together easily and I did a test hookup to the trailer.
The mechanisms work easi I y and smoothly, unlike my previous hitch that was an absolute fight to disconnect.
Curt products seem to be a better quality than others I've had.
Service this time was excellent, she knew what I needed, and sold it to me.



by:

The A25 hitch is great; just as expected. But, havent to say something about the great, personal, pleasant and expert people that helped me. They were terrific! I highly recommend trailer for your needs.

  • Troubleshooting Curt A25 Fifth Wheel Hitch that Has Stuck Latch
    Hey Mark that is a bummer to hear. Have you been lubricating it at all this time? I know it's easy to forget to do that but if you do skip the components can get frozen up and hard to use. So I would go with your next plan and grease it up real nice like and I would be willing to bet it will work again. Worst case scenario we do have a replacement head unit for the A25 with the part #C16580.

  • B&W Companion or Curt A25 Which is Lighter and Easier to Remove from the Ram Puck System?
    You are correct the B&W Companion does weigh more then the Curt A25 at 42 lbs. Here are the break downs below of the individual weights. I recommend the B&W Companion over the Curt for reliability and it is made in America. I have linked a solution below that will help you offset the additional weight. The B&W also detaches with pins over the Curt which requires you to unscrew bolts. The B&W Companion OEM 5th Wheel Hitch for Ram Towing Prep Package item # BWRVK3600 weighs 226 lbs. The...

  • Can the Jaws Be Replaced On the Curt Q25 5th Wheel Hitch
    I spoke with Curt about the Curt Q25 5th Wheel Hitch and was informed that they do not offer the locking jaw mechanism as a replacement part. I know this is not what you wanted to hear but the fact remains. That said, if you want you can replace just the head and center section with the Replacement Head Unit for Curt Q25 5th Wheel Trailer Hitch part # C16565 but this would be a good time to upgrade to the Replacement Head Unit for Curt A25 5th Wheel Trailer Hitch part # C16580. The A-Series...

  • 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 are...

  • How To Upgrade a Curt A16 Hitch to an A20 or A25
    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.

    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.

  • How Much Does the CURT A25 Weigh?
    I would be happy to help you break down the weight of the Curt A25 5th Wheel Trailer Hitch for Ram Towing Prep package item # C16046. The entire unit weighs 184 lbs.

  • Does Curt A25 Head Attach To Curt OEM 5th-Wheel Hitch Legs With Four Bolts
    Hey Kevin! That is correct. Do you already have of these parts in hand? The A25 Head # C16580 only comes with four bolts for installation. The reason the # C16017 has the extra set of holes is for different heads. The A25 just happens to have an extra row of holes to fit different legs. If you look at the A16 head it is narrow and mounts on the inside holes which can be seen in the installation video below. Something like a Q20 head is wider and fits the outside holes. All of them are using...

  • Replacement 5th Wheel Hitch Head With 24,000 lb to 30,000 lb Rating
    Essentially all 5th wheel hitches now have articulating or fully pivoting heads, though we do offer replacement heads with the weight rating you are looking for, and I will list all of them for you below: - Replacement Head Unit for Curt Q25 5th Wheel Trailer Hitch - 25,000 lbs # C16565 - Replacement Head Unit for Curt A25 5th Wheel Trailer Hitch - 25,000 lbs # C16580 - Replacement Head Assembly for B&W Companion 5th Wheel Trailer Hitches - 25,000 lbs # BWRVC3006

  • Replacement 5th Wheel Hitch Head for Curt 25K
    If you have the Curt Q25 hitch head # C16565, there have been many people who have had a similar issue. Curt came out with another hitch head the A25 # C16580 which has a better latch system and a different pivoting system. This hitch head is able to fit all the same bases as the Q series 5th wheel hitch head. I don't believe there was any recall on these.

  • Is The Rota-Flex Pin Box Compatible With Curt Q24 5TH Wheel Hitch?
    You are correct the Curt Rota-Flex 5th Wheel Pin Box # LC328329 is not compatible with the Curt Q24 5th Wheel Trailer Hitch w/ Slider. This will require you to either change out your pin box or the Q24 head for the A25 Head # C16580. To determine the correct replacement pin box for your 2023 Dutchman Astoria 2993RLF I will need the Lippert chassis tag information to verify with Lippert what pin box bolt pattern your 5th wheel uses.

  • Is Curt C16020 Slider Assembly for Ford OEM Puck System Compatible With The C16580 A25 Hitch Head
    Curt has confirmed that their # C16020 slider for the Ford factory puck system is compatible with the # C16580 A25 fifth wheel head. However, be aware that the # C16020 slider has a weight capacity of 24K, so it would lower the capacity of the # A25 hitch head to 24K.

  • Does The Curt A25 Hitch Head Fit The Curt Q25 Legs For A 2022 GMC Sierra 3500?
    Yes absolutely! The Replacement Head Unit for Curt A25 5th Wheel Trailer Hitch # C16580 will work great with the Curt R24 Round Tube Slider for Q24 5th Wheel Trailer Hitches C16570. You will be limited to the 24K capacity of the slider base, however.

  • Can Curt A25 5th Wheel Hitch Head Fit Q20 Legs From Ford Puck System
    Yes, you can use your current legs; I verified with Curt that for the puck system on your Ford truck, the Curt Q20 # C16530-16017 and Curt A25 # C16036 5th wheel hitches both use the same legs, the Curt OEM 5th-Wheel Hitch Legs for Ford Super Duty Towing Prep Package # C16017. So you can use the legs you have now, and upgrade simply by adding the A25 head unit, which is the following part number: - Replacement Head Unit for Curt A25 5th Wheel Trailer Hitch # C16580

  • Will the Mopar M25 Head Work on a Curt S25 Slider?
    Yes, it will. The Mopar M25 head is the same as the Curt A25 5th Wheel Trailer Hitch Head item # C16580. The Curt S25 Slider for A25 5th Wheel Trailer Hitches item # C43DR is designed for the A25 Head item # C16580. You will also need the Adapter Rails for Curt 5th Wheel Hitch item # C47BR to attach it to your 2018 Chevy Silverado 2500's factory puck system.

  • Is Curt A25 5th Wheel Head Compatible With Legs of Curt A16 for 2020 Ford Super Duty Prep Package
    The answer to all of your questions is yes! They are compatible and you can buy the hitch head separately if you like. The Curt A16 5th Wheel Trailer Hitch with Ford OEM Legs # C16520-16017 uses the exact same legs as the Curt A25 5th Wheel Trailer Hitch for Ford Towing Prep Package # C16036, which are the Curt OEM 5th-Wheel Hitch Legs for Ford Super Duty Towing Prep Package # C16017.

  • Will the Curt A30 Head Fit Curt Q24 Legs/Base
    I do have an option but the Curt A30 5th Wheel Trailer Hitch Head part # C16590 will not work with Curt Q24 5th Wheel Legs due to the presence of a dowel pin that is only on the GM legs/base. However, you can use the Curt A25 5th Wheel Trailer Hitch Head part # C16580. Therefore, if you have a Curt Q24 5th Wheel Hitch you can simply swap out the Q24 for the A25. The A-Series is much better than the Q-Series so even though you won't get much added capacity you will still see ride quality...

  • Can Curt Q20 Legs be Installed on an A25 Hitch Head on a 2014 Ram w/Factory Puck System
    The Q20 legs are fundamentally different than the A25 legs. If you have the Q20 head you can use Curt base # C16021 for the factory puck system in your 2014 Ram.

  • Curt A25 Head Compatibility With R24 Sliding Roller Base.
    The Replacement Head Unit for Curt A25 5th Wheel Trailer Hitch - 25,000 lbs # C16580 has a compatible bolt pattern to the Q25 head # C16565. The A25 will absolutely fit on the R24 slider base # C16570 according to my contact at Curt. He said the 16K rollers don't fit because they are designed to not allow for the larger head but the larger rollers like the R24 are compatible.
