2021 Ram 1500 - Reese Quick-Install Custom Outboard Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches

  • Above the Bed
  • Custom
  • Reese

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.


Features:

  • 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


Specs:

  • 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.

2021 RAM 1500 with 5'7" Box, Split Tailgate & 3.0l ECO Diesel

It fit, but it took a day and a half to install, mainly from needing to drop the folding step, disconnect the fuel tank, lift the bed up 6" & grind two brackets off the underside of the bed that I'm assuming must be bolt up location for the optional "RAM BOX". In their defense I could have probably done it in 4 hours with a full-on shop that had a 4-post hoist & lots of room to work, lay out tools, parts etc.

To those that are considering ordering this, don't fool yourself with a 4 hour install if you're like me with a 2 car garage. Prepare for a full weekend of work & keep the CL Smoothies in the fridge until you're done for the day, this is not a "have a few beers and turn some wrenches" project, you'll need a cool head and your wits about you.

You'll definitely need a die grinder with a tungsten cone bit as well as a 4-1/2" angle grinder with cut off wheels to grind off spot welds and trim a 1/16 - 1/8" off misc brackets on the truck itself.

One other thing, keep your impact off the 7/16" carriage bolts, those are not grade 8 and they will snap. Also keep an eye on the blocks they ship out for backer washers to those carriage bolts, if they over lap (the ones in particular are the 2 bolts that are stacked side by side), they will snap. Hand tighten them and make sure they're aligned before torquing or you'll be in for a headache.

The photos I attached are of the bracket that needed to be removed & the misc grinding you may need to do. Keep an eye out for those brackets, they'll be towards the front of the box. If you have those, get ready for an exciting weekend you'll be talking about for a while.

  • Can 2020 Ram 1500 with Ram Box Tow Fifth Wheel Trailer
    Hey Craig, In order to tow a fifth wheel trailer using a 2020 Ram 1500 with RamBox you'll need to use a rotating pin box like the Reese Sidewinder which will be specific to the trailer. This is so that the pivot point is moved up high enough that the Ram Boxes won't get hit around corners. If the trailer uses a Lippert 1621 then the correct Reese Sidewinder 5th Wheel King Pin with Rotating Turret is part # RP34FR. Then, you can complete the setup with the Reese Quick-Install Custom Outboard...

  • 5th Wheel Hitch and Installation Kit for 2019 Ram 1500 5-1/2 Foot Bed With Rambox
    The B&W Patriot # BWRVK3200 will not work for your 2019 Ram 1500 with a 5-1/2 foot bed, and it is not recommended to use any 5th wheel hitch in a bed that short with Ramboxes. If you do, you will need a Sidewinder such as the Reese Sidewinder Fifth-Wheel Pin Box # RP34FR. To find the correct Sidewinder what you will need to know is the manufacturer and model number of the pin box on your fifth wheel and match that with the correct replacement. For example, Sidewinder # RP34FR will replace...

    There is one option for 5th wheel base rails that fit your 2019 Ram 1500 short bed with air suspension, so long as your truck does not have the Multi-Function tailgate.

  • 5th Wheel Hitch Installation Bracket/Rail Kit for 2021 Ram 1500
    2021 is a split model year for the Ram 1500, with two different models being available. The 1500 Classic is a carryover from the previous generation, while the Ram 1500 is the all new model. If you have the Ram 1500 Classic, I'd recommend the Reese # RP50142-58 custom install kit. For a less expensive option, a semi-custom kit is available as part # RP30035-523. The semi-custom kit would take an hour or two longer to install. For a Ram 1500, only a custom install kit is available as part...

  • Fifth Wheel Rail Kit that Fits 2023 Ram 1500
    Since you have Reese fifth wheel rails all you would need is the correct bracket kit to mount them in the new truck you end up with under normal circumstances. With that said we only have the outboard style of Reese fifth wheel rail kits available for the 2023 Ram 1500 with the part # RP56018-53.

  • What 5th Wheel Hitch Do I Need For My 2022 Ram Big Horn
    I do have a solution for you, but there are quite a few variables. Your 2022 Ram Bighorn is available in all three sizes, 1500, 2500, and 3,500. I am not sure if you have the 5th wheel Load & Towing Groups package or if you have the Ram 1500, so I will recommend two 5th wheel hitches. One that will be compatible with a 5th wheel tow package and one that will not be compatible with that setup. If you have the 2500 or 3500 Big Horn with the 5th wheel tow package, I recommend the following: B&W...

If you don't have the OEM prep package for towing a 5th wheel trailer then you'll also need a rail kit; for that I recommend using the Reese Quick-Install Custom Outboard Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches # RP56018-53.

  • What 5TH Wheel Hitch Do I Need For a 2022 Ram 1500 That Has a 5'6" Bed?
    A fixed 5th wheel hitch like the Reese 5th Wheel Trailer Hitch # RP30047 is recommended because you only have the 5-1/2' bed on your 2022 Ram 1500. Your 5th wheel will need to have a king pin with a rotating turret like the Reese Sidewinder # RP34FR. Rather than a sliding hitch that will move the pivot point back 10-12 inches, the Sidewinder moves the pivot point back 22". This gives you more turning radius than a sliding hitch would offer and also will not require you to manually slide...

  • Which Base Rails to Install 5th Wheel Hitch on 2019 Ram 1500 with Short Bed

  • 5th Wheel Base Rails/Install Brackets for 2021 Ram 1500 6-1/2 Foot Bed
    For the 2021 Ram 1500, the kit needed will depend on if you have a Ram 1500 or a Ram 1500 Classic-they use different kits. For the Ram 1500, use # RP56018-53. For the 1500 Classic, you'd use # RP50142-58 both will place the 5th wheel king pin roughly 2-3/4 inches forward of the centerline of the rear truck axle.

Now since you have the air suspension the correct rail kit you'd need is the part # RP56018-53 which also provides the same rail design as what the Demco needs. The Valley hitch you have now would not give you enough clearance and without knowing what pin box you have on your trailer...
