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.

2019 Jeep Wrangler

This is our second tow vehicle. etrailer made it easy to shop for our 2020 Jeep Wrangler Sport. We purchased a Blue OX base plate for our Mini Cooper previously and the videos make it easy to install. We use the Blue Ox Alpha 2 Tow bar and the Roadmaster BrakeMaster System w BrakeAway for RVs w Air or Air Over Hydraulic Brakes - Proportional. Can't wait to get the new Jeep set up.

Jeep Wrangler

Just what I needed to flat tow my Jeep Wrangler. When I first received the base plate I was thinking about having it installed, but after watching the installation video I decided to do it myself. Couldn't have asked for a smoother install. The permanent base plate safety cables concerned me a little. I came up with a figure-8 over the frame that I think will work ok and I did secure it with some cable ties in a couple of spots.
Thanks to Nick at etrailer for the help and to the folks that made the installation video giving me the confidence to do-it-myself.

The base plate still works great and looks good too. No issues.
Joseph - 03/04/2021


Quality product. Solid, well built, perfect installation fitment. I installed this on a 2020 Jeep Wrangler JL and had no problems. Bumper and lower facia removal were easy (check out the online video...great instructions.) Base Plate installation was an easy, one-person job. (FYI I'm 72 and not in great shape, so if I say it was was easy!) Total time invested was about 2 hours.

2018 Jeep Wrangler

We decided to purchase the Blue Ox set up for our 2018 Wrangler JL. The set up works very well and has been easy to connect/disconnect, so far. The instructional installation video was EXCELLENT and definitely contributed to making the installation a breeze. Thanks again etrailer. Only alteration was to the brake away switch. It seemed to stick out too far in front of the bumper, for my liking, so I added a stainless nut/bolt and two nylon bushings so it could swivel out of harms way when not in use.


The ease of set up and use is just fabulous. The only drawback for me is the battery life. We have used this on several trips and only get about 7-8 hours of use before needing a charge. So, if you are planning a long day of driving, plan to charge during a stop or 2.


Received the baseplate today. Thanks for the help with this purchase.


First endeavor on 4 down towing a 2018 jeep Wrangler JL. Use to use tow dolly but couldn’t understand why we went that direction. This is a very stout piece of hardware. Installation took about 3 hours. Referred to etrailer’s installation video which was very well done. Only recommendation i would make is to specify that a 18mm DEEP socket is required to remove bumper. Very pleased with this purchase which arrived 3-4 days after placing order. No hesitation on using etrailer for all my RV towing needs. Great job etrailer!


It’s a well engineered and thought out product. However, it’s meant to put on the front of a vehicle and get wet. A year later we have some black paint peeling and rusting around the outer holes and around both removable connection points. I’m disappointed for the price, but I don’t know a better product for this use. I suggest keeping a close eye on this and treat rust early on.

The base plate will experience nicks and scratches over time from road debris. We do recommend keeping a can of Rustoleum on hand to touch it up from time to time.
-- Etrailer Expert Jenny N - 09/11/2023


Well built. Nice addition to Jeep for towing. Clean looking after you get installed.

2023 Jeep Wrangler

The Blue Ox Baseplate arrived in excellent condition. Thanks etrailer / Joshua!


Great product and easy to follow detailed instructions.

Jeep Wrangler

Base plate has been perfect. I did the install on my 2020 Jeep Wrangler and we've towed it many miles using a Roadmaster Nighthawk towbar.

2023 Jeep Wrangler

This is my 3rd baseplate, I replace it every time I buy a new Jeep, and it’s a great product as long as it’s installed correctly. I also like the fact that it’s made in the USA.

2023 Jeep Wrangler Unlimited

Blue Ox base plates always do the trick! ETrailer is the best to buy from if you want fast delivery and quality merchandise.

2021 Jeep Wrangler Unlimited

I have this unit on another Jeep , easy to use.


The powder coating on the Blue Ox Base plate came off upon the firt time I inserted the pins to tow it.

Jeep Wrangler

Overall, a great product. Fit my 2020 Jeep Wrangler perfectly. Tucked up tightly against the bottom of the bumper so doesn’t look too obtrusive. Installation instructions we not that great, but excellent etrailer videos made the installation straight forward. Just allow yourself enough time and don’t rush.

2020 Jeep Wrangler Unlimited

Exceptional delivery time (2 days)! Packaged perfectly, no issues at all. Waiting on the back-ordered Blue Ox accessory kit to begin install. Can't wait to start!


Product fit very well and instructions were very accurate. It does help to watch the video as well. This is the second tow vehicle I have used etrailer for but will probably have the Jeep Wrangler for a while now. I like how you don't really notice it when on the vehicle.


If you’re looking for a professional, quality product, this is what you need and purchasing through etrailer made all of this so much easier. A small piece of advice, watch as many of the E trailer videos you can that applies to your vehicle installation. It will make the job easier and answer most of the questions you’re going to have during installation. They have great YouTube videos for your application.

Jeep Wrangler

Perfect for flat towing my wrangler. Doesn’t alter the look of the vehicle much.


Correct product and easy assembly. Wonderful communication with Ashley.


I’ve used many of the Blue Ox base plates and tow bars over the years. I have never had any problems with any of their products. I would highly recommend Blue Ox products to anyone looking to flat tow your vehicle. Hook up and release has never been easier.

2022 Jeep Wrangler 4xe

Works as described! Easy to install the base plate. Fit perfectly.

2018 Jeep JL Wrangler Unlimited

After receiving a defective removable tab/pin as part of the Blue Ox base plate I contacted Etrailer for a replacement part. Alex cut thru the red tape and was able to send me a new set of pins very quickly as I was getting ready for a trip and was running out of time.

    From the sound of your question, I assume that you are looking to see if your base plate from a 2017 Jeep Wrangler JK will fit your newer 2021 Wrangler. The compatibility of a Blue Ox Tow bar for a 2017 Jeep Wrangler JK with a 2021 Jeep Wrangler depends on what bumper setup you have on your vehicle and how you are mounting your base plates. For example, if you have a standard factory bumper on your 2017 model and are using the Blue Ox Base Plate # BX1126, you will need to get a new base...

    Yes, the trailer wiring kit part # 118786 and the tow bar wiring kit part # RM-15267 will both easily fit on your 2020 Jeep Wrangler at the same time. You'd install the trailer wiring exactly like the instructions detail by installing the connectors inline with the taillight wiring and then you'd use the diodes of the # RM-15267 installed on the vehicle wiring before the trailer wiring and everything would work just fine. I attached install videos for both kits for you to check out as well.
