Simple, Hidden Design

Blue Ox Base Plate With Arms AttachedBlue Ox Base Plate Arms Removed

This base plate's hidden design creates a clean and seamless look. The bracket arms are easily removable, creating a slick appearance when you're not flat towing. Because the arms can be removed, you also won't have to worry about banging your leg into any protruding arms when you walk by.


Blue Ox Base Plate Removable Arms

Attaching and removing the bracket arms is a breeze. To attach the arms to the base plate, simply insert them into the receivers and rotate them until they lock into place. Once you're finished towing and want to remove the arms, pull the pin to disengage the lock, rotate the arms, and remove them from the receivers. Finally, plug up the now empty receivers with the included receiver covers to help keep dirt and debris out of the base plate and provide a finished look.


Guide to Flat Towing

Flat towing your vehicle is much more convenient than using a trailer or a tow dolly. These other options take up much more storage space, leaving you less room both at home and at the campsite. In addition, securing your vehicle to a trailer or tow dolly can be a hassle and more time consuming than hooking up with a tow bar.


There are 5 basic components needed when flat towing a vehicle: a tow bar, a base plate kit, a safety cable set, tow bar wiring, and a supplemental braking system.


Towing Basics

The tow bar links your towed car to your motorhome. It attaches to the custom-fit base plates that install on the frame of your towed car. Safety cables ensure that your towed car does not separate from your motorhome in the event that your tow bar becomes detached. Tow bar wiring allows your towed vehicle's signal lights to sync up with your motorhome's tail lights, which is required by law in most states. Finally, the supplemental braking system - also required in most states - brakes your towed car when the brakes in your motorhome are activated, preventing wear on the motorhome and decreasing braking distance for your entire setup.

  • Parts Needed to Flat Tow 2018 Jeep Wrangler JL With BrakeBuddy Supplemental Braking System
    To flat tow your 2018 Jeep Wrangler JL you will need to start with compatible base plates; because you have a Blue Ox tow bar and assuming you have the standard factory bumper the best option is the Blue Ox Base Plate Kit # BX1139 which will be compatible with Blue Ox tow bars Alpha # BX7380, Avail # BX7420 as well as Aventa, Aladdin, Adventurer, Ambassador, Acclaim, Allure, and Trion. If your Blue Ox tow bar does not have integrated safety cables you will need those and can use the Blue...

  • Parts Needed to Flat Tow 2025 Jeep Wrangler Sport
    Hey Dellos, the Blue Ox base plate and tow bars are in my opinion the easiest to use and are also very well made so I would recommend the Blue Ox part # BX1139 with the tow bar part # BX7420. Then for lighting the Curt kit part # C96JR is a very simple install so that would be a great choice as well. And finally, most states now require supplemental braking in the vehicle being flat towed. The easiest system to set up and use is the Blue Ox Patriot # BLU37TR, that applies the vehicle...

  • Will The Blue Ox Baseplate # BX1139 Fit A 2024 Jeep Wrangler Rubicon X With A Steel Bumper
    Hi Joe, The Blue Ox Base Plate Kit # BX1139 is a confirmed fit for your 2024 Jeep Wrangler Rubicon X per Blue Ox. I don't currently have an installation video on a model with a steel bumper but I did measure from the mounting holes down to the crosstube so that you can measure from the mounting hole locations on the frame to see if it will clear the bumper. If you need anything else just let me know and I'd be happy to help.

  • Blue Ox Base Plate Kit for Flat Towing 2025 Jeep Wrangler with Ascent Tow Bar
    Hey Joe, since you will have a Blue Ox tow bar you will want a Blue Ox base plate kit and for that the correct fit for your 2025 Jeep Wrangler Unlimited is the part # BX1139. For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow vehicle to control the taillight assemblies of the towed vehicle. This comes with a round 6-way connector that you will install on the front...

    Hey John. To use a Falcon tow bar with the Blue Ox Base Plate Kit item # BX1139 you'll need the Roadmaster Tow Bar Adapter Brackets for Blue Ox Base Plates item # RM-031.

    Hey John, since you have a Blue Ox tow bar you'd want the Blue Ox Base Plate kit part # BX1139 which is a confirmed fit for your 2020 Jeep Wrangler.

  • Recommended Flat Towing Setup for a 2025 Jeep Wrangler
    Hey Dennis, congrats on the new Jeep. You have to have a baseplate like item # BX1139 or a bumper rated to be flat towed with and then use an adapter like item # BX88357 to flat tow your 2025 Jeep Wrangler. Not all bumpers are rated to be flat towed. If you go the route of an aftermarket bumper with the intention of using it to flat tow you must make sure it's rated to be used this way.

  • Can Trailer Towing Wiring Be Installed When Flat Towing Wiring Is Already Installed?
    Great question, Victor! You can absolutely install trailer wiring if you already have flat towing wiring installed. The vast majority of trailer wiring will install inline with the taillights, just as most of the flat tow wiring does. Installing both will not negatively affect either system and we have people do it very often. For your 2025 Jeep Wrangler, I would recommend going with the Tekonsha T-One # 118786. This does install in the manner mentioned above and Tekonsha is known for...

  • Blue Os Base Plate For A 2025 Jeep Wrangler Unlimited JL
    Hi John! We have the Blue Ox Base Plate Kit - Removable Arms # BX1139 for your 2025 Jeep Wrangler Unlimited JL, but it will install the same way as the one on your '08 model (see first included picture). The only way to get away from that would be if you had the off-road bumper that had D-Rings ( # BX88357 for 7/8" or # BX88358 for 1"). The # BX1139 does also include attachment points for the wiring plug and a break away switch, so I guess there is that. If you don't mind going with...

Another potential part you may need is a high low adapter, but you will want to get the base plate installed first to see if you need one or not.

    Hey Paul, for your 2021 Jeep Wrangler 4xe we have the Blue Ox base plate kit part # BX1139 as a confirmed fit that would work great. It has brackets for lighting as well too. There isn't a way to use your trailer wiring in reverse as tow bar wiring so you would want to install the Curt kit part # C96JR which installs basically in the same way by plugging inline with the taillight connectors. This does use a 4-way style connector so if you were for sure wanting a 6-way style you'd have...

  • Base Plate Kit for 2025 Jeep Wrangler Rubicon
    Hi Bruce; I don't have that measurement handy for the # C68FR but I can tell you it won't work. The Rubicon comes standard with the steel bumper and this only fits if you have the factory plastic bumper. What base plate kit did you try before? Was it the Blue Ox Base Plate Kit # BX1139? This is designed for any factory bumper style and unless you have made modifications to your 2025 Wrangler there is no reason it wouldn't fit.

    Hey Paul, since you have a Blue Ox tow bar already the easiest solution is to go with a Blue Ox base plate kit part # BX1139 that fits your 2019 Jeep Wrangler. You could go with a different brand base plate kit but you'd then have to use an adapter which would add expense and extra steps so it wouldn't be worth it. Then for lighting we have the Blue Ox kit part # BLU79FR which does not require any splicing and would work great for you. Do you have everything else?

    No, it won't but I have something that does. Since you're using the etrailer tow bar item # e47ZR and what I am assuming is a Blue Ox base plate like item # BX1139 you'll need to use the Sentry Deflector etrailer Tow Bars item # DM9523135. The Sentry Deflector item # DM9523135 is designed specifically to work with etrailer tow bars. These vehicle guards all match up with the same brand of tow bar.
