Fits Q20 perfectly


Delivery was fast the packaging was bad not heavy enough cartoon for parts to be sent in. It was all broke apart by the time it got to me. . No parts where missing though, Thank god. Brackets were little scratched up, we touched them up a little with black paint. I would rate the service at a 4 though. BETTER PACKING NEXT TIME

Hi Paul, Thanks for your feedback! Our customer service team will be reaching out to you.

  • Can Slider Unit on Curt C16536 Q20 5th Wheel Hitch Be Replaced with C16904 Leg Kit
    Absolutely. The Curt # C16904 Replacement Base Legs are fully compatible with the Curt # C16536 Q20 5th wheel hitch center section/hitch head. You don't mention the length of your truck bed, but be aware that the Curt Q Series isn't compatible with rotating pin boxes like the Reese Revolution/Sidewinder or Lippert Turning Point. I've linked to a product description video that explains the features of the Curt Q20 5th wheel hitch.

  • Best Way to Tow a 5th Wheel with Flat Bed Truck
    I have a solution for you, but the Curt Q legs # C16904 that you're looking at are only going to come in one size and the Curt Q head when attached to any of the available legs is always going to sit between 13-17" tall. With that being said, the best solution to tow a 5th wheel trailer with a flatbed truck is going to be using the Reese Low-Profile Hitch # RP30054, which is adjustable between 9-1/2" and 12-1/2" tall and will provide you with a way to compensate for the added height of...

  • Is Curt Q20 Sliding 5th Wheel Hitch Compatible With 8 Foot Truck Bed?
    The Curt Q20 sliding 5th Wheel Hitch # C16536 can absolutely be used in your long bed Ram. The sliding base isn't needed for a long bed, so it is a little heavier to install but will have no other issues. If you want new base legs for an easier installation you can use the Replacement Base Legs for Curt Q20 5th Wheel Trailer Hitch # C16904. This swap out will make a 93 lb difference as well as give you a more solid hitch because there won't be as many moving parts. You may also want...

  • Curt Fifth Wheel Hitch Recommendation that Smoother Than E16 Slider
    The Curt E16 slider hitch has a lot of play in the slider assembly like you noted but also quite a bit in the jaw system as it's a slide bar style that allows the king pin to move around quite a bit when latched. If you wanted a much smoother Curt fixed hitch your best option is the Curt A16 hitch part # C16120. The jaw design of this hitch provides a 360 degree contact with the king pin which holds it very tight and minimizes noise. Now the head will be located right over the rear axle...

  • Replacement Legs for a Curt Q5 5th Wheel Trailer Hitch
    For your Curt Q5 5th wheel trailer hitch you will need legs # 16125-SK13. Even though you have a long bed truck you can still use the slider hitch. You would just keep it locked in the towing position since there will not be a need to slide it back.

  • Replacement Base for Mopar M20 5th Wheel Hitch to Fit Standard Base Rails
    It sounds like you have a Mopar M20 5th wheel hitch that is designed to fit in the 5th wheel prep package on Ram trucks but you have standard base rails in your 2014 Ram 1500 like the Curt # C16306-204. If this is the case the solution is actually pretty simple because the Mopar M20 is just a re-branded Curt Q20 hitch and what you'll need is to replace the base of the hitch so it fits standard base rails. For that you'll need the Curt R20 Round Tube Slider for Q20 5th Wheel Trailer Hitches...

  • Will a Curt 5th Wheel Hitch From a Chevy Silverado Fit a 2010 Ford F-250
    The Curt 20K 5th Wheel Hitch will work on your 2010 Ford F-250 but I would need to know what base that 5th wheel hitch has in order to see if additional parts are needed. If it installs via pucks like the Curt Q20 5th Wheel Trailer Hitch part # C16530-16025 then you can reuse the head and center section but you will need a new base along with above bed rails for your truck. If it installs via above bed base rails like the Curt Q20 5th Wheel Trailer Hitch part # C16130 then all you will...

  • Compatible Legs For A Curt Q20 Fifth Wheel Hitch
    No, the legs of a Curt A16 # C16120 are only rated for 16,000lbs so they would not be compatible for use on a Curt Q20 # C16130.

If your truck has an in-bed puck system then you'll want one of the following legs depending on the brand of your truck: Curt OEM 5th Wheel Hitch Legs for Chevy/GMC Towing Prep Package # CU53FR.
