Reese Fifth Wheel Installation Kit

  • 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.


  • Installation brackets mount beneath your truck bed to provide attachment points for 5th-wheel rails
  • Base rails sit in truck bed and allow installation of 5th-wheel trailer hitch
  • Fast, simple installation with outboard design
    • Extended-length base rails allow for mounting farther out from truck frame
      • Avoids underbed components for easier access
      • Cuts down installation time by more than half compared with universal kits
    • Custom brackets mount to existing holes in truck frame, minimizing drilling and measuring
  • Thoroughly tested kit is compliant with strict Society of Automotive Engineers guidelines
  • Kit includes brackets, 10-bolt rails and Grade-8 hardware
  • Compatible with Curt, Draw-Tite, Hidden Hitch, Husky, Reese and Valley 5th-wheel hitches
  • Sturdy, black powder coated steel resists corrosion


  • Base rail dimensions: 48" long x 1-7/8" tall
  • 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.

Ordered this hitch for my 03 ram 3500 shortbed and didnt get a chance to install it untill 2 months later. Which is when i noticed it was missing some hardware. I contacted etrailer and they shipped me the missing hardware at no cost to me, how can you beat that anyone else would have said go pound salt its been 2months . The installation was cut and dry with good instructions. I like how the hitch installed onto the frame and the quality of the parts its built heavy, its agriculture approved lol. Thanks again etrailer for the unbeatable price and fantastic customer service

This kit was pretty easy to install. Took 2 guys about an hour and a half to complete. The install video was extremely helpful. We watched it several times before we began. Everything fit like a glove and looks great. Will definitely buy this kit on my next truck. The hardest part was cutting the flimsy bed liner. Thanks Reece and Etrailer.

Great kit the you tube video was very h elpful

We got off on a rocky start because the parts weren't correct in the box but that wasn't etrailer's fault.. Etrailer went above and beyond to correct the problem and I greatly appreciate it.. product fits great and I'm very pleased. Fair price also.. Will do business with etrailer again

Instructions were great & installation was easy. High quality parts that looked great and are holding up well. Etrailer and Cequent (Reese's parent co.) are both great companies to deal with - extremely knowledgeable and helpful with the products they sell.

I installed this rail kit in about 4 1/2 hours including cutting out the bedliner. The instructions were perfect. It fit great. The staff at e trailer led me to this model kit and I'm glad they did. Great product

  • Fifth Wheel Base Rails and Installation Kit for 2006 Dodge Ram 2500 MegaCab
    The best base rail kit, so that you do not have to drill holes in the frame of your truck, I recommend using is the Reese Quick-Install Custom Base Rails and Outboard Installation Kit # RP56011-53. This custom install kit will make use of the pre-drilled holes in the frame of your 2500. The outboard bracket will also make for easier installation by avoiding any components to allow easier access to the installation hardware.

  • Will Reese Outboard Installation Kit Fit with Load Assist Air Bags on a 2012 Ram 2500
    I spoke with my contact at Reese who said that the load assist air bags on your 2012 Ram 2500 should be aftermarket. Since they aren't OEM, which Reese would have performed a test fit with, I can't necessarily verify that they will work with the Reese Quick-Install Custom Outboard Installation Kit # RP56011-53 that you referenced without knowing what exact air bag kit you have. If you can let me know what you have and send in a picture with it then I could verify it that way for you. Attached...

  • Recommended 5th Wheel Base Rails for 2013 Ram 2500 Short Bed
    Without seeing the hitch in question or knowing the exact model, it's hard to say with confidence what kind of deal it is, however the price you mentioned is going to be hard to beat if it is in fact barely used and in good condition. You did mention though, that you were told that it was an "auto slide" hitch from Reese. Reese does not currently produce an automatically sliding fifth wheel hitch, so most likely you are looking at a manual slider (unless the seller misspoke when he said...

  • Easy Install Fifth Wheel Rail Kit Recommendation for a 2010 Dodge Ram 2500

  • Bracket Kit Recommendation to Install Reese 5th Wheel Rails in bed of 2004 Dodge Ram 3500
    We have just what you are looking for to install your current Reese rails and fifth wheel hitch in your 2004 Dodge Ram 3500. What you need is the Reese bracket kit # RP50140 which comes with brackets that are custom fit for your 2004 Dodge Ram. You'll also need the hardware kit part # RP58504 which connects the rails to the brackets. You may have this already but these kits are considered one-time use so it's important you replace them as well.

  • Can Dodge Ram 2500 with Ram Boxes Tow Fifth Wheel Trailer
    The problem with the Ram Box is that is that it puts the rails of the bed too close together and it causes interference with the pin box of the trailer around corners. We have heard several customers say that with a Sidewinder pin box they were able to tow a fifth wheel trailer with a truck with a Ram Box. Sidewinders move the pivot point higher so the Ram Box wouldn't interfere. You will need to remove the pin box of the trailer and replace it with a Sidewinder pin box. Sidewinders...

  • RBW Lil Rocker is Not Fitting in Reese 5th Wheel Installation Kit # RP56011-53
    The only things that are different between the rails in kit # RP56011-53 and the regular rails is that the -53 rails are longer overall and the tops are a bit wider. The spacing for the hitch feet is still the same. There are 3 sets of mounting slots. The inner set is 10 inches apart on center, the middle set is 20-1/2 inches apart on center, and the outer set is 29 inches apart on center. Front to back they should be 22 inches apart on center.

  • 5th Wheel Bracket/Rail Mounting Kit for Demco Hijacker SL Series on 2011 Ram 3500 Long Bed
    You'll need the Demco SL Series frame brackets and bed rails which are provided with the # DM8553004-12 bracket/rail kit. The SL series is a sliding hitch, so because you have a long bed truck, you'll want to leave the hitch slid forward in its towing position at all times. If you'd like to install a 7-way trailer connector in the bed of the truck so you won't have to run the trailer connector cable up over the tailgate, you can install one using part # 20110.

  • Recommended 5th Wheel Hitch for Towing a GVWR 16,250 lb Trailer with a 2006 Ram 3500 Short Bed
    Typically we recommend going with a 5th wheel hitch that is rated for about 2,000 lbs more than what the GVWR of your trailer is. That way if you were to totally max out the weight of your trailer your hitch isn't maxed out as well. Since your 2006 Ram 3500 is a short bed you will want to look into getting a sliding 5th wheel hitch to avoid trailer-to-cab contact when taking sharp turns. The best option for you to go with would be the Demco Hijacker Autosliding 5th Wheel Hitch. This...

    There is an option to tow a fifth wheel trailer with your 2012 Ram 2500 6 Foot Bed with Rambox. The issue with using a fifth wheel trailer hitch with a Rambox is your truck's bed is thinner. Therefore taking away clearance you will need for your trailer to make turns. The way to gain this clearance is with a Sidewinder.

    Reese does not recommend fifth wheel towing with Rambox-equipped Ram trucks.

There have been reports that using a Sidewinder will produce enough clearance that this danger is removed, but Reese hasn't tested it and therefore cannot recommend it.
