2024 Ram 3500 - Reese Quick-Install Custom Outboard Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches

  • Above the Bed
  • Reese
  • Custom

Heavy-duty, custom brackets dramatically reduce the amount of drilling and time required to install your fifth-wheel trailer hitch. Outboard design ensures simple access to mounting points. Brackets, 10-bolt base rails and hardware included.

  • Base rails sit in truck bed and allow installation of 5th-wheel trailer hitch
  • Fast, simple installation with outboard design

      • Avoids underbed components for easier access
      • Cuts down installation time by more than half compared with universal kits

  • Limited lifetime warranty

Reese's outboard installation kit for your fifth-wheel trailer hitch was designed with safety and convenience in mind. Just like the original custom mounting brackets, these brackets install using existing holes in the truck frame, minimizing installation time. The biggest difference with this outboard kit is the extended-length rails. These above-bed rails are 5 inches longer than standard, universal fifth-wheel rails so that they will match up with the mounting points on the brackets, which sit below the bed and outside of your truck's frame. The result is a much simpler installation process, wherein most underbed components can be easily avoided. Because you are working outside the frame rails, you also have easier access with your tools and more room to work, making the whole process less of a pain.

The base rails included in this installation kit feature a standard 10-bolt design. Each of these rails attaches to the underbed brackets with two carriage bolts at both ends. A single bolt is used in the center of each rail to further secure it in your truck bed. The result is a set of base rails that remains firmly in place thanks to 10 points of contact.

This entire installation kit is built to be SAE J2638 compliant and has been extensively tested per specified accelerated-life-cycle criteria for fifth-wheel trailer hitches. The requirements for testing are based on the European-style test of 900,000 cycles, making this testing process among the most thorough and intensive in the industry.

The 5th wheel base & rail kit came fast and the installation was quick and relatively easy

Dodge Ram Pickup

Bought this kit for my 2022 Ram 3500 long bed. This is kit fit perfect. Driver side you had to move wiring harness out of the way. Just take your time and it will go exactly as advertised. Great product. Want to thank Rodney for finding the right fit for my vehicle.


This product is simple and easy to install taking about 3 hours the prep work is the hardest part of the install


Installed as said was strait forward looks great and works great.

2020 Ram 3500



Upgraded my truck to a 2019 F250 Superduty. Received my new rail kit and mounting brackets. Fits perfect!


The costom bracket kit is of heavy steel,powder coated for protection, from your video it is going to be a lot easier to install and save time,alot less drilling and mounting of components, I am very satisfied with this product and cannot wait to install it on my 2013 Ford f150,will be pulling a 25 foot 5th wheel camper, thanks trailer for a great product


Five hours to install; which included a half hour searching for the key to the padlock on my spare. E-Trailer linked me to an installation video which really helped. I took my time and measured three times before I drilled the bed. Installation is a lot easier with someone to hold the bolts from the top. I fabricated mounting brackets on my last truck, but these were worth the money and I didn't have to drill the frame! Good design and straight-forward installation. My only issue was the video didn't show one bolt install that secured the driver's side rear bracket to the bottom of the frame. I was going off the video only and wasn't using the written instructions. Make sure you go step by step using both. Also, some parts are clearly for a different application so there will be a few parts left over. My experience with e-trailer was awesome.


Very happy how soon the product I ordered was at my door step. 3 days after I ordered it. Put the base to my 5th wheel on my 2017 250 diesel sd took me around 5 hrs, would have been faster with 2 people. The base fit my husky 16k prefect when I done torquing all the bolts. Going to use this hitch to pull my 29.5 Durango EZ 1500.


Installation was good and very happy. Thank you


This did not fit my truck right. Front brackets fit fine. The rear brackets lined up with all the holes but the chassis strap brackets are wrong. The spacers are also too short. Contacted e trailer. They checked inventory said their boxes were all wrong also. They contacted the mfg and i waited a month only to get a box of bolts and spacers and no straps. Had to have some fabbed locally. This is for my 2024 silverado 2500 custom.

The item looks great but the brackets are both for the passenger side of the truck. I called and etrailer is shipping out another set. My only real complaint is delayed shipping and I am now running behind on my install.


Still waiting for my package that was supposed to be here yesterday. It's been bouncing around 2 states clear on the other end of the country. I'll change my review if it ever shows up at my door.


Very easy to install. Measure twice, drill once. I used every piece of galvanic corrosion tape to protect the aluminum bed in the kit, probably could have used a little more. Even though I painted the edge of the holes after drilling, maybe some sort of insulator could be used there also.


We ordered a bracket kit for our new 2017 F350. It was needed to install our Reese fifth wheel. which we use to pull our RV. Product was on back order by manufacturer, however Delisa at Etrailer diligently kept us very informed with updates & shipping status. My husband & son were able to install in a couple of hours. Looks great, outstanding craftsmanship & over exceeded our expectations! We would highly recommend!!!!!


Fits great and works well on my 2005 Sierra 1500 ( 5 1/2 )short bed.


The product was fine but the service from the etrailer folks Is excellent. I had issues with my order (my fault) and they did everything they needed to do to get my issues resolved. Their service was very much appreciated!


They fit truck just like they were supposed too. Couple hr install with having to remove spare tire and heat shields to get access to bolt locations. Been supporting fifth wheel through thousands of miles. Thanks for helping me find right product for my truck!


The kit arrived within a few days-very happy about that. very easy to install. the directions were clear and pictures good. I went to the trouble of using a sharpie to mark the part numbers on everything before I started just to keep to all straight.

I would note that on the 2017 F350 diesel the only problem bolt was on the driver side inline with the DEF tank. long skinny arms with flexible wrist is ideal (not what I have). I would also suggest taping the shims onto the outboard frame brackets to save yourself some frustrations. otherwise they are difficult to get and keep in place, especially on the driver side.

the two nuts that go inside the frame tube come on/with a nice handle although a bit light on the wield. here again save yourself and tape the shims on before you try to insert two things into that hole, align and fasten the bolt-by yourself. I used an extension with wobble head and socket to turn the bolt while holding the nut "assembly" in place.

I did remove the rear wheels and fender well liner-a must.

Lastly, great customer service on the phone. Pleasant and patient answering questions.

Perfect fit, easy install. Appears to be be a quality product. Shipping was both great and terrible. The brackets sit at my UPS 2 days before they would deliver. UPS kept showing processing for delivery.


Installing 2017 5th wheel brackets and rails . Thankyou for your service in sending me the right parts for my F250 . Took about 4 hrs to install and all holes were perfect in the side brackets . Just had to drill for the rail. I’d recommend your service...


What an interesting product to install. The mounting to the frame is easy. Getting the bolts through the bed and putting the nuts and washers on the bottom take a lot of patience. There is not a lot of room for your hands to fit between the bed and the frame. I took my spare tire down and I was able to sit under my truck that helped a lot.



Used it 3 times so far, does what it’s supposed to, the brackets fit the frame very good. Very happy with the setup.


Awesome service
Received my order fast
with two days
I highly recommend etrailer for all your needs

  • Will 5th Wheel Trailer Hitch Install Kit from a 2013 Ram 2500 Fit a 2015 Ram 3500
    Like you said, the brackets required to install a 5th wheel hitch are different between the 2013 and 2015 Ram trucks so the kit off of a 2013 will not fit a 2015. For the 2015 Ram 3500 short bed you would need kit # RP56010-53. I have included links to the installation instructions for you.

  • Recommended Fifth Wheel Hitch For 2016 Ram 3500 With Short Bed And Ram Boxes
    There is a way you can tow your toyhauler with a short bed Ram 3500 with Ram Boxes. You will need to install a fixed fifth wheel hitch and then a Sidewinder pin box on your trailer. I recommend part # RP56010-53. This will give you the standard in-bed rails. You will then need to replace the pin box with a Sidewinder. The Sidewinder you choose will be based on the pin box you have on your trailer. There should be a sticker or plate that has the pin box number. Just let me know what pin...

    In order to determine if there are mounting brackets available for your 2014 Dodge Ram 3500 using the rails from your 2006 Chevrolet, I will need to know what brand of rails you have and whether they are a 4-bolt or 10-bolt. I have attached a picture that shows the two different types of rails. If unable to use your current rails, we do offer the Reese Quick-Install Custom Base Rails and Outboard Installation Kit, # RP56010-53.

    I have a solution for you, but Curt does not have any installation kits available yet for the 2020 Ram 3500. The good news is that because you don't have the OEM prep package, you'll just need a set of industry standard base rails to be compatible with your existing hitch. I recommend using the Reese Quick-Install Custom Outboard Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches # RP56010-53, which will give you industry standard base rails in your truck bed compatible with...

  • Availability of 5th Wheel Frame Brackets to Install Pullrite 2900 on a 2015 Ram 3500
    The Pullrite 2900 is designed for industry standard 5th wheel rails, so it would work with the Reese # RP56010-53 install kit you mentioned. For just the frame brackets and hardware, you'd need part # RP56010. However, because the Reese frame brackets and your existing bed rails (assuming they weren't manufactured by Reese) have not been tested together, so their capacity as a unit would be unknown. This is why we recommend using bed rails and frame brackets from the same manufacturer...

  • Towing a 5th-Wheel Trailer with 2017 Ram 3500 Short Box with RamBox
    I do have a possible solution for you, however we do not currently have a Reese Elite below bed installation rail kit that is confirmed to fit your 2017 Ram 3500 short box with RamBox. Because your truck is equipped with the RamBox feature, which results in a narrow truck bed, I recommend using a fixed 5th-wheel hitch along with a Reese Sidewinder Pin Box. The Sidewinder will move the pivot point 22 inches behind the king pin and is needed to prevent the pin box from contacting the RamBox...

  • Could a 2015 Ram 3500 Tow a 16,000 lb Travel Trailer
    Your 2015 Ram 3500 would have no problem towing a 16k fifth wheel trailer. You can check the towing capacities in the owners manual but I can guarantee they capacities are higher than needed to tow a 16k fifth wheel trailer. To use the Reese Select Plus fifth wheel hitch # RP30081 that you referenced will only require the installation of a fifth wheel rail kit. For you truck you would want the part # RP56010-53 since your truck has a long bed without the hitch prep package.

  • Fifth Wheel Hitch and Rail Kit Recommendation for 2015 Ram 3500 Short Bed with Sidewinder
    You will need to remove the pin box of the trailer and replace it with a Sidewinder pin box. Sidewinders are pin box specific so you will first need to know what pin box you have now in order to pick out the correct one. There should be a sticker or a stamping on the OEM pin box of the trailer that will list the pin box number that is on the trailer. Once you figure out which pin box you have you can check the FAQ I attached that has a chart that shows the correct Sidewinder to get based...

  • Fifth Wheel Trailer Hitch Recommendation for 2017 Ram 2500 Short Bed Towing Keystone 284rdbwe
    I checked out the Keystone 284rdbwe you have and it has a tapered nose designed to allow it to be towed with a short bed truck and not need a slider. For your 2017 Ram 2500 with a short bed that does not have the factory rail kit I would go with a stationary hitch since you don't need the slider and slider hitches are much heavier and have more moving parts which means more movement. So for a hitch the # RP30047 would be a great choice. Then for a rail kit I'd recommend a custom fit kit...

However, you should note that Reese does not confirm that the Sidewinder will work with the Rambox. We have only heard from people who have tried it and it did work for them. Surprisingly there isn't an underbed Reese Elite setup I can recommend for your vehicle. I checked with Reese and the removed their listings for your vehicle. The...

Still, we have heard reports of successful installations in the 2014 Rambox-equipped trucks using a Sidewinder replacement pin box.

For a custom installation kit you can use Reese kit # RP56010-53. I have linked the install instructions for you.
