Reese Quick-Install Custom Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches - RP50085-58

Average Customer Rating:  4.2 out of 5 stars   (6 Customer Reviews)

Custom brackets reduce the amount of drilling and time required to install your fifth-wheel trailer hitch. Brackets, base rails, and hardware included.

by:

Very good no problem installing every so often just go over the bolt on the frame of truck for tightness




by:

Very poor design for the Ram 3500. The front brackets have four holes to secure the rail. Two are used and the other two bolts use spacers and the bed to secure the rail. Should be designed to use all of the bracket for a stronger hold on the hitch.

2018 Ram 3500

I've bought 2 Reese Quick Install kits this year, the sales reps at etrailer were very helpful.Shipping times great. Did have wrong bracket in one order, was taken care of promptly.




by:

Front brackets do not have a specific spot they can be installed, So it just makes it harder to line up properly before drilling into your bed




by:

Excellent, well built, well designed kit. Install went without any issues.

  • Under Bed Brackets Only for Reese 10-Bolt Rails and a 2016 Ram 3500 Short Bed
    For your 2016 Ram 3500 short bed and Reese rails you can use custom brackets # RP50085. These are the brackets by themselves without the rails. It comes with the necessary hardware to attach the brackets to the frame and the rails to the brackets.

  • 5th Wheel Installation Kit for a 2015 Ram 3500 Dually Short Bed
    As long as your 2015 Ram 3500 dually short bed does NOT have the 4 pucks (factory 5th wheel prep package) then you will be able to install a 5th wheel installation kit such as # RP50085-58. I do believe that models that do not have the prep package all have that beefy cross member that you are referring to. I have included a link to the installation instructions for you.

  • Fifth Wheel Rail Kit Recommendation for 2015 Dodge Ram 3500 for Draw Tite Slider Hitch
    For your 2015 Ram 3500 we have rail kits that will work with your Draw Tite slider hitch. Best option would be a custom install kit that will install much quicker than a universal style kit and will minimize drilling. For that you'd want the # RP50085-58 which is a confirmed fit.

  • 5th Wheel Hitch Install Kit for 2014 Ram 3500 Crew Cab Long Bed
    According to my Reese representative, with the 2014 Ram 3500 you need to use one of the Custom Install Kits, such as part # RP50085-58. The custom install kit doesn't require any holes be drilled into the truck frame (just up through the bed to join the rails to the frame brackets). The RBW Lil Rocker is compatible with industry standard bed rails, so it will be compatible with the bed rails supplied with the kit I recommended above. If you don't already have a 7-way installed in your...

  • Is Valley Powerpull 5th Wheel Hitch Compatible with Reese Industry Standard Truck Bed Mounting Rails
    The Reese # RP50085-58 bracket/rail kit is compatible with your truck. If memory serves correctly, the Valley PowerPull was compatible with the industry standard bed rails that Reese (and other companies) uses. You can confirm this for yourself by measuring the spacing of your hitch mounting tabs that insert into the rails front to back and side to side, center on center. Compare the results with the photo I've edited for you. The tabs, when measured front to back should be about 22 inches...

  • Fifth Wheel Rail Kit Recommendation for a 2015 Ram 3500 to Install 22k Reese Fifth Wheel Hitch
    To install the Reese 22k Fifth Wheel Hitch part # RP30033 in your 2015 Ram 3500 without the factory rail kit will only require you to install the correct fifth wheel rail kit. For that you would want the custom install kit that will minimize drilling on your vehicle and will cut install time considerably. For that you would want part # RP50085-58.

  • How to Tow a 5th Wheel Trailer with a 2018 Ram 3500 Short Bed Rambox
    As long as you are using a Sidewinder pin box, you should not have any problems with a 5th wheel trailer on your 2018 Ram 3500 with Rambox. The Rambox limits the side to side clearance in your truck bed which is problematic for fixed pin boxes as they will likely contact the inside of the bed. Using a Sidewinder will move the pivot point away from the bed sides and will allow for greater turning clearance and minimized interference. Unfortunately, an under bed mounting kit is not compatible...

  • Parts Needed to Install Draw Tite Fifth Wheel Hitch in Bed of 2019 Ram 3500
    The Draw Tite hitch you have was designed to fit industry standard fifth wheel rails so if your 2019 Ram 3500 has the OEM rail kit you'd need the part # RP30156 to install the hitch or if you didn't have the rail kit you'd need the custom rail kit part # RP50085-58 and you'd be set.

  • Reese Fifth Wheel Rail Kit that Fits 2020 Ram 3500 without OEM Rail Kit
    Reese has fifth wheel rail kits that fit your 2020 Ram 3500 but due to the design of the truck you'd have to use a custom fit since none of the universal kits fit the truck. So Reese has the # RP50085-58 which is a fit that would be a much better option than a universal kit as it does not require frame drilling and also minimizes install time.

  • Easiest to Install Fifth Wheel Rail Kit Recommendation for 2018 Ram 3500 Long Bed
    We do have custom fifth wheel bracket kits that fit your 2018 Ram 3500 but you'll need to make sure that the rails you have are Reese since we can't recommend mixing rail and bracket manufacturers. If you do have Reese rails all you'd need is the bracket kit part # RP50085 which is custom fit for your truck. If you have a different brand of rails are you aren't sure what you have then we have to recommend you go with an all new rail kit part # RP50085-58 which gives you the same bracket...

  • Reese Quick-Install Custom Bracket Kit for a 2018 Ram 3500 with a 6-1/2' Bed
    The correct Reese Quick-Install Custom Bracket Kit for a 2018 Ram 3500 with a 6-1/2' bed is the part # RP50085. The part # RP50054 is only a fit for a 2018 Ram 2500. We have the complete base rail kit available as part # RP50085-58 but if you already have the Base Rails # RP58058 then you would just need the Bracket Kit # RP50085 and the Replacement Hardware # RP58430 since the hardware is only supposed to be torqued to specs one time.

  • Recommended 5th Wheel Trailer Hitch Install Kit for 2014 Ram 3500
    I recommend the Reese custom kit, part # RP50085-58, for your 2014 Ram 3500. Since it's a custom install it reduces the amount of drilling and time required for the install. It'll give you industry standard rails which the Anderson Ultimate, part # AM3200, will fit right into.

  • Custom Fit 5th Wheel Base Rails and Installation Kit for 2015 Ram 3500
    The 5th wheel hitch base rails and custom installation kit I recommend for your 2015 Ram 3500 is the Reese Quick-Install Custom Base Rails and Outboard Installation Kit # RP56010-53. The custom installation brackets will not require you to drill into your vehicle's frame, and the outboard orientation of the brackets will make it easier to access the installation hardware. These base rails are industry standard rails, so they will work well for your Husky 24K 5th Wheel Hitch. If you're...

  • 5th Wheel Rail Kit Confirmed To Fit 2017 Ram 3500 6 Foot Bed Without Factory Rail Kit
    For your 2017 RAM 3500 6 foot bed, the rail kit # RP50085-58 is a confirmed fit. If you want the easier to install outboard kit, the # RP56010-53 is also a confirmed fit. The benefit of the longer rail of 48 inches versus the 43 inch rail is ease of install, but length of rail could be a drawback depending on your perspective.

  • Fifth Wheel Rail Kit for 2018 Ram 3500 Short Bed
    So for your 2018 Ram 3500 we have semi custom rail kits like the part # RP30035-520 and fully custom fit kits like the # RP50085-58. The semi-custom kit is the easiest on price for sure but it requires quite a bit more time and involvement for the install. There will be frame drilling etc. Whereas the custom install kit will utilize holes already present on the frame for a much simpler and easier install.

  • Comparing Reese Quick-Install Custom Installation Kits for a 2020 Ram 3500
    The Reese Quick-Install Custom Installation Kit part # RP50085-58 and part # RP56010-53 are both correct for a 2020 Ram 3500. The difference is that the latter comes with outboard base rails and the former comes with inboard base rails. The outboard base rails are easier to install since they attach outside the frame whereas the inboard base rails are harder to install since they attach inside the frame but that's it.

    In order to install a Reese 5th wheel hitch in the bed of your 2014 Dodge Ram 3500, I recommend using the either the Reese Quick-Install Custom Inboard Installation Kit part # RP50085-58 or the Reese Quick-Install Custom Outboard Installation Kit part # RP56010-53. The only difference between the two is where the connection points are for the frame brackets and base rails. On the inboard kit the connection point for the frame brackets and base rails are located inside the frame rail and...

  • Recommended Fifth Wheel Hitch For A 2021 Ram 3500 With Ram Boxes
    Since your 2021 Ram 3500 has Ram boxes you will most definitely want a rotating pin box like the # RP61422 to prevent the pin box from coming into contact with the bed rails. This will also increase the turning radius because you'll be pushing the pivot point back 22". Pin boxes have specific bolt patterns so you'll need to find the correct replacement for your trailer's current pin box. If you need help determining the correct fit then just send me some pictures of your current pin box...

  • Can a Single Attachment Point B&W Companion 5th Wheel Hitch be Used with a Sidewinder Pin Box
    You actually shouldn't be using a B&W Companion hitch with a Sidewinder at all. The problem is because of the single attachment point and the force applied to the hitch from the Sidewinder it could cause the gooseneck hitch under the bed to get damaged or even break free causing the whole assembly, including the Companion, to rotate. The only difference between the regular Companion and slider is that the slider can slide back to allow more clearance between the truck and trailer when...

  • Fifth Wheel Hitch Rail Kit for Husky Hitch in Bed of 2016 Toyota Tundra 6.5 ft Bed
    For a set of fifth wheel rails that fits your 2016 Toyota Tundra with a 6.5 foot bed the best option is a custom install kit as it will minimize drilling and install time. For that you'd want the Reese kit part # RP50085-58 which is a fit for your truck and also provides the style of rails that your Husky hitch requires. Husky makes a universal style rail kit that fits your truck too but since it will be a much more difficult install and the Reese kit works just as well it would be your...

  • Will the B&W Companion Work With Sidewinder On 2018 Ram 3500 with RamBox
    I do have an option for you but in order to tow a fifth wheel trailer using a truck with RamBox like a 2018 Ram 3500, you'll have to go with a pin box with rotating turret as that's the only way to clear the bed sides. Pin boxes with rotating turrets like the Reese Sidewinder cannot be used with gooseneck to fifth wheel adapters like the B&W Companion. Therefore, the only option would be a new fixed fifth wheel hitch. I recommend the Reese M5 5th Wheel Trailer Hitch part # RP30928 with...

This route would not require any drilling into the frame.
