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.

    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.

  • Base Plate Kit for Blue Ox Tow Bar on 2021 Jeep Wrangler
    The etrailer # e98948 Base Plate Kit is a confirmed fit for your Jeep with standard factory bumper.

  • 6-Pin Socket That Works with the 6-Pin Bracket on a Blue Ox Base Plate Kit # BX1139
    I tried looking up what 6-pin connector you have to try and see why it was not working with the Blue Ox Base Plate Kit # BX1139, but was not able to locate anything. Any 6-pin socket like what is included in the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 (included photo) should be able to work with that base plate kit. If you are unsure, you can send in a picture along with what 6-way you are using and I would be happy to take a look.
