Video Transcript for Hands-On with the Curt OEM 5th Wheel Hitch Legs for Ram Towing Prep Package

Hello, everybody. This is Jeff at etrailer.com. Today we're gonna take a look at the CURT OEM Fifth Wheel Hitch Legs for the RAM Towing Prep Package. Has a 25,000 pound gross towing weight capacity. Now, this is a custom fit part. It is designed to fit the 2013 and newer RAM 2500 and 3500 trucks, with the eight foot long bed, and the factory installed underbed towing prep package.

This custom base is specifically designed to attach to the receivers in your RAM's trucks factory installed underbed fifth wheel towing prep package, and it'll adapt most CURT fifth wheel hitch heads to fit the RAM puck system. The heads will attach right here. And they are designed, these legs here will work with the following CURT hitch heads. They work with the A16, the A25, and the E16, and they also work with the Q20, the Q24, and the Q25 hitch heads. All those hitch heads, we do sell separately on our website.

And that'll install this into the factory underbed system. I just wanted to show you. It uses the quarter turn anchoring system for a quick installation and removal, just to demonstrate that, we're zoomed in on this one leg. And you'll do this on all four legs. But what you'll do is flip up this safety pin, and take out the safety pin.

And you can see it's tethered, so you won't lose it. Once that's out, just move this away, and then just rotate this 90 degrees. And you can see, if you notice, when you rotate it, that tab at the bottom will rotate, and that'll let you take it out. In other words, when you open it like that, that's in the unlocked position. So, you do this on each leg, and now you're ready to drop this into the factory system on your RAM truck.

Once these drop into the pucks that are in your factory system, then you just take this, rotate this back, and by doing that, it rotates the tab here and locks it into the puck. And then, to make sure it stays, you just put your safety pin through there, and that will hold that in spot. And again, you'll do that on all four legs. And these anchors right here, they can be adjusted to eliminate movement between the legs and the underbed rails. Now, the finish on this, it is co-cured in a rust resistant liquid A coat, and it is protected by a durable carbide black powder coat finish. Again, the gross towing weight capacity is 25,000 pounds. But that should do it for the review on the CURT OEM Fifth Wheel Hitch Legs for the RAM Towing Prep Package, and this has a 25,000 pound gross towing weight capacity.

I purchased this Curt 5th wheel hitch base for my 2022 Ram 3500. I had a Q25 5th wheel head and needed the base for the factory puck system. I transport RV's both bumper pull and 5th wheels for a living. The Curt 5th wheel hitch has worked flawlessly.

One year update since my last review on this product. Its still working flawlessly.



by:

Fits as it should. I haven't pulled with it yet.



by:

Fairly easy install but recommend having help. It’s quite heavy once assembled with the head mounted. One of the cords that holds the rings to the legs snapped as soon as I tried to insert it for the first time. Other than that, this product is great. Fits perfectly.



by:

Fit to my existing curt Q20 fifith wheel hitch. Dropped right into the holes on the RAM frame, and fit perfect. Easy to assemble,with only 6 bolts and the price was right.

The hitch legs worked exactly as expect ed.



by:

Very well built. The hitch is heavy and requires two people to remove or put in easily. I use my skid steer to put in and take out. I am very pleased with the hitch and glad I bought it.

In my opinion this is the best hitch made. I would recommend it to anyone.

Great product would highly recommend



by:

As always etrailer customer service is excellent. The item shipped right away and was actually delivered ahead of schedule. The fifth wheel hitch legs fit perfectly with our Curt A16 hitch head and they fit perfectly in our 2021 Ram 2500 truck. They were very easy to install. I cannot give 5 stars due to the poor packaging and scratches on the hitch legs during shipping. Curt really needs to tune up how they package these heavier items. Other than so far so good.

Nice looking and heavy duty.

Worked perfectly to update/upgrade my rail to puck.

Product was easy to assemble. Purchased it after trading in my old truck and needed a factory prep frame for the new vehicle. My Curt 16k hitch head that I was using with a universal sliding mount fit perfectly.

Recieved my Ram oem Curt 5th wheel legs today. Ordered last Thursday and received them today Wednesday. Excellent price with free shipping. Box was beat up but everything I have ever received from Curt has been. Parts are heavy and burly. Everything purchased was included, no damage. I will use etrailer in the future. I am pleased.



by:

It went in easy



by:

I had a base that I bought from the ram catalog at my dealership. Don't do it. It is heavy and cumbersome and hard to handle. The folks at etrailer helped me locate a better and easier to handle base for the fifth wheel head I had from Curt. I ordered and they shipped it from stock and I received it in less then 48 hours from ordering. The etrailer people are really great to work with.I feel like I have found the right combination for supply to us for our trailer and towing needs. We have an Open Range 5th wheel and etrailer has provided all we missed to make it a great towing experience. Thank you all for your assistance.... and follow-up.

I have shopped with etrailer previously and this last order was as good as the first. Product was delivered ahead of time of scheduled delivery. The legs that I ordered for my fifth wheel hitch fit perfectly I am very pleased with service and products.

This was my first time ordering RV-related parts from etrailer. Noah E, my contact via phone, was very knowledgeable in assisting me to order the right item. I'm very pleased with etrailer and I'd return to this company for future needs for my RV.

The folks were very helpful getting me set up for towing my rv with the new puck hitch from the my old rail system. Thanks again it works great!

This mounting base for the ram puck system is well built and heavy duty.very simple to install. I definitely recommend

I just want to thank this girls over the phone. They were great. My hitch was lost by UPS and right away sent out a replacement. Great job I will always buy from this site. etrailer is the best

  • How To Install a Curt A25 5TH Wheel Hitch In a 2024 Ram 2500 With Factory Prep/Puck System
    You have a couple options for installing the Curt A25 5th Wheel Trailer Hitch # C16180 in the bed of your 2024 Ram 2500 with the factory in bed hitch system. First we have the Adapter Rails # C29BR which fit into the pucks and give you the ISR mounting points. Do note this will raise the hitch 2" so you will likely need to lower the height of the hitch. The next option is replacing your ISR Base # C16907 with the Ram Base # C16021 so you can install the hitch directly into the factory...

  • How Can I Swap My Curt A25 From My Chevy 2500 OEM Prep to My 2024 Ram 2500 With OEM Prep?
    Hello Cory, If only the truck manufacturers would use the same OEM Prep Package layout, you would not be in this predicament. You’ve got a couple of ways to install the Curt A25 5th Wheel Hitch # C16180 in your 2024 Ram 2500 with the factory OEM Prep Package. You and your wife look like such lovely people, so it pains me to say that is indeed going to cost you a pretty penny..... One option is to use the Adapter Rails # C29BR, which drop right into the factory pucks and give you standard...

  • Will Curt Fifth Wheel Legs for Dodge OEM Prep Pkg Clear Bed Mounted Fuel Tank
    I think the legs will fit just fine. To fully open the locking arms, they're turned 90 degrees from their locked position, which does NOT have them pointing directly to the front which would place them close to the fuel tank. Since the locking arms measure about 7-1/4 inches from the center of the bolt to the end, and they wont extend fully forward, I'm confident that the location of your fuel tank won't interfere with the locking arms. You will be able to install and remove the legs with...

  • Curt Ram OEM 5th Wheel Hitch Legs Compatibility with Q16 Hitch Head
    The Curt OEM 5th Wheel Hitch Legs for Ram Towing Prep Package - 24,000 lbs # C16021 is compatible with the Q16 head which has been discontinued. They are absolutely compatible and will allow you to use the hitch on your Ram OEM factory puck system. If you don't have the 7-way in the bed of your truck you may want to consider adding # PK11893-11932 to give you a second 7-way and the convenient access location for the clean look.

  • Can A Hitch For Ford Pucks Be Converted To Fit Ram Pucks?
    Hi Jim! There is most likely a way to do what you are wanting to do, but I want to be absolutely sure before just flat out saying yes. Is there a way you can send a few pictures of the hitch's head unit to [email protected]? Specifically any labeling on it. Odds are you just need the Curt OEM 5th Wheel Hitch Legs for Ram Towing Prep Package - 25,000 lbs # C16021 and you will be good to go, but this doesn't fit all the Curt head units and I would strongly dislike giving you bad info.

    Hi Jacob; your Curt A20 head # C16540 is compatible with the Curt OEM 5th Wheel Hitch Legs for Ram Towing Prep Package # C16021. Your hitch will then be the same as the # C16044 which fits the 2020 Ram 3500 prep package. Any big trips planned with your 5th wheel this fall?

    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...

  • Will Curt A16 5th Wheel Hitch Fit Factory Pucks on 2022 Ram 2500
    Great question! You will be happy to know that you can utilize your Curt A16 Slider # C16521 with the puck system on your 2022 Ram 2500. All you need is the Adapter # C16022, which fits the long and short beds, to accomplish this. If you have the short bed then you'll still use the slider function but if you have the long bed you'll have enough clearance to keep the hitch in the regular towing configuration. For the long bed you can also remove the A16 Head # C16520 and install it directly...

You said "forward side" and I'm not quite sure if that meant the bolts closest to your Ram's cab or tailgate, so I'll go ahead and list both options for you. - Anchors Closest to Tailgate: Replacement Rear Anchors # C48UR - Anchors Closest to Cab: Replacement Front Anchors # C68UR

  • Factory Prep Package Puck Adapter to Universal 5th Wheel Rail Compatible Hitch for Ford, Ram & Chevy
    The Curt Q25 5th Wheel Hitch # C16265 will work with an adapter for the puck systems. You simply need to recognize that some adapters will limit the towing capacity. Curt is one of the hitches that uses legs compatible with the different pucks, so I will give you both options. For a Ram, you will use Reese adapter # RP30154 or Demco # DM6099. You can alternatively use the Curt legs # C16021 which will mount directly to your pucks. For a Chevy or GMC, you will use the Curt OEM 5th Wheel...

  • What is the Difference Between the Curt A16 Head and the Curt E16 Head for My 2022 Ram 2500?
    As far as the difference between the Curt A16 Head # C16520 and the Curt E16 Head # C16515 for your 2022 Ram 2500, the E16 is more of a basic economical hitch. With the A16, that hitch comes with a dual-jaw that makes for better kingpin connection which will make for a quieter ride. In addition, the A16 comes with a 3-point, color-coded lock indicator system that gives you the status of the locking mechanism. With all being said, I recommend the Curt A16 head because it will ultimately...

Please note, this adapter will raise the hitch head height by 1-1/2".

However, the Curt OEM 5th Wheel Hitch Legs for Ram Towing Prep Package part # C16021 that the above hitch uses is compatible with the Head Unit for Curt A20 5th Wheel Trailer Hitch part # C16540 which is compatible with rotating pin boxes like the Lippert Turning Point.

  • Will Curt Q20 Head Work with Curt OEM Puck Legs?
    Great idea! You can use the head of your Curt Q20 5th Wheel Hitch # C16130 with the Curt 5th Wheel Towing Legs for Ram Towing Prep Package # C16021. The head of your hitch is actually part # C16530 when it's a stand-alone product. I attached videos of both parts so you can see them in action. You can also pick up some penetrating grease like # L11354 to help out with the whole process.

  • 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. You would instead need the Replacement Base Legs for Curt Q20 5th Wheel Trailer Hitch # C16904. 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.

The Rail Adapter # RP30154 that you would use to mount in to the puck system on your 2018 Ram 2500 sits about 2" tall so that means your height range will increase to 15"-19". If you were to instead use the Curt OEM 5th Wheel Hitch Legs # C16021 this gives you the Curt Q20 # C16530-16021 which has a height range of 14"-18". I personally recommend going with the new legs for the Q20 as it eliminates...
