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...

  • Blue Ox Parts Needed to Flat Tow 2020 Jeep Wrangler with Steel Bumper
    We've checked with Blue Ox and the base plate kit part # BX1139 is a confirmed fit for your 2020 Jeep Wrangler so it would work great with your Blue Ox tow bar like the # BX7420. The Demco Air Force One part # SM99243 is a great choice for braking as well. For lighting the Roadmaster kit part # RM-15267 is a great choice that splices into your taillight wiring and allows your motorhome to operate your Jeep taillights when flat towed.

    Hi Marcus! I see you went with the Blue Ox Base Plate Kit - Removable Arms # BX1139 for your 2024 Jeep Wrangler Unlimited Rubicon. As long as you have the factory plastic or steel bumper, this options will be a perfect fit. The Blue Ox Acclaim Non-Binding Tow Bar - Coupler Style for 2" Ball - Car Mount - 5,000 lbs # BX4330 will work for you as long as you have the standard 3.6L V6 as it will weigh roughly 4,500 pounds.

  • 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.

    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.

    Hi Gerald! I was going to say you also needed the Blue Ox Base Plate Kit # BX1139 and some wiring to hook the RV to your Jeep, but I see that you realized this and got both. 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. You want to # BX7380 tow bars to be as level as possible, but the RV hitch and base plate arms being within 3" is perfectly acceptable. If it's more than that, you will want...

    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...

    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...

  • Blue Ox Base Plate and Lighting Kit for 2019 Jeep Wrangler
    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?
