Features to know about

Made for a Clean, Factory Look: Hidden Base Plate with Removable Arms

If you like your front end to stay clean and uncluttered when you’re not towing, this setup is built for that. The completely hidden design keeps the brackets out of sight, and the removable arms twist off in seconds. Receiver covers plug into the openings to keep out dirt and debris while giving a finished look. Nothing sticks out past the front, so it’s easy to walk around without bumping into hardware.

Quick Hookup Every Time: Twist-Lock, Pin-Secure Arms

Connecting your tow bar doesn’t have to be a chore. Each arm slides into the base plate receiver, twists to lock, and secures with a simple pin. When you’re done towing, pull the pin, rotate the arm back out, and you’re free. It’s a straightforward process that makes setup smooth whether you’re in your driveway or at the campsite.

Strong Where It Counts: Durable Steel Construction That Spreads the Load

This base plate bolts directly to your chassis—no welding required. The sturdy steel build and precise design spread towing force evenly across the frame to help protect your suspension from stress. Powder coating adds rust and corrosion resistance for long-term reliability through thousands of miles of use.

Ready for Your Tow Bar Setup: Broad Compatibility with Adapter Options

You can keep your favorite tow bar setup with this kit. The sturdy lugs pair directly with Blue Ox tow bars for a secure and reliable connection. If you run a Roadmaster setup, use adapter RM-031 or RM-031-5 (sold separately). For Demco systems, adapter DM9523041 (sold separately) makes it fit right in. Integrated mounting points let you easily add an electrical connector plug bracket (sold separately) up front to keep things organized.

Built for Real-World Use: Precise Fit and Practical Specs

With a distance between brackets of 24" and bracket height of 14", this setup offers reliable alignment for consistent towing performance. Every piece bolts securely with included hardware, forming a solid connection built for everyday travel or long cross-country hauls—all backed by a 3-year warranty.

Custom designed to fit your vehicle so it can be safely towed behind your RV, this base plate has easily removable arms that offer a seamless look when you're not flat towing. Base plate bolts directly to your chassis, so no welding is required.

Instructions could have been better but was straight forward and easy to figure out. Had to widen two holes on vehicle a tiny bit to align up with plate. Was shorted two connectors to attach the safety cables to the vehicle and base plate. None mentioned on inventory but two were included. Picture showed using four.



by:

Well designed and solidly built base plate. Very good product support from Etrailer and Blue Ox.
The four 1/2 inch by 1 3/4 inch bolts are category 5 bolts. I had a bag full of identically sized bolts which were category 8. But I did not have any whizz nuts that were category 8 nuts so I stayed with the standard Blue Ox Hardware. We used POR 15 rust preventing paint at every location where we cut the steel or drilled holes. The distance from the center of the attachment tab assembly holes to the ground is 20 inches on our 2025 Wrangler Rubicon JLU with "Xtreme" 35 inch tire package. Easy five stars for Blue Ox and etrailer.



by:

had to spread it apart 1/4" to make it go over the rails, hammering the pinch welds wasn't enough. poor weld on one of the plug in supports. fit good otherwise, video was very helpful.



by:

The Blue Ox base plate kit was installed without a hitch on our 2024 Maverick Hybrid. It was a perfect fit! It was installed by Fantasy Truck, a referred installer of etrailer, in Odessa, MO. Brett was very easy to work with and did an excellent job! I highly recommend the Blue Ox baseplate and Brett @ Fantasy Truck!



by:

Two day delivery! I'm impressed. I have not installed yet because I just got them. It appears that everything is all there. I am excited to do the install of the base plate and the hitch and the wiring harness.



by:

Was an easy installation. Only problem is instructions are vague on getting nuts in frame for 7/16 bolts.



by:

After installing over 500 baseplates on various vehicles, this one was probably the toughest one . It had the off road package on it . But it fit great after I had to remove a lot that had been bolted up for 27yrs.



by:

Fits my 2013 mini cooper non turbo. Does take a few hours to install this Fit was good. The hardest part is removing the front bumper and reinstalling it. You do have to cut the lower bumper grill in three places take your time locating the exact spots for cuts. I have pulled Mini Cooper about seven thousand miles now with this Blue Ox and has worked great



by:

I was given a Blue Ox Tow Bar and needed Base Plates for my Ford F150. In my online search, E-Trailer had the best price, so I ordered them. Delivery was a few days earlier than expected. I read the installation instructions and it sounded fairly simple to install, so I decided to tackle it myself. I began it about six pm and had the job completed and cleaned up in just over two hours. The job required removal of the bumper and tow hooks and drilling of two holes. Also William at E-trailer was of great help in the correct parts and keeping me informed of the delivery.



by:

The safety Cable installation left a little to be desired. I'm not sure if I installed it as designed. The cables we're really long enough to go aroiund the frame rails on our Jeep, under the Radiator mount, Aluminum Frame, I was only able to go around the Raditor mount on both sides. Didn't really seam like it was the right way, but I suspect it's only for if something comes loose that there isn't a catastrophic breakaway.



by:

Tried to install this baseplate. It was a challenge to say the least. It did not fit the frame of my Jeep YJ without making modifications to the mounting plates on the driver side. I had to use a cut off wheel and remove 3/16 of an inch from the driver side spacer (which is too long. See pictures) in order to get it to clear the frame. Also, instructions say to drill an additional 1/2 inch hole in the frame for a third mounting bolt. BUT....the internal frame construction doesn't allow the nut on a stick to pass under the existing reinforcements for the bolts that mount the steering gear to the frame. Nut is way too thick to pass under the internal tubing in the frame from manufacturer (AMC).



by:

Base plate for flat towing my Jeep behind the bus was ordered Monday afternoon and was delivered to my house on Wednesday early afternoon, MO to NC! It was exactly as described and was very well packaged. Best online transaction I recall in 20+ yrs.



by:

Part fit like a glove, a tight one (a hammer gets it in place so no need to clamp after), but lined right up with the factory holes. I only had to do some minimal drilling to make the bolts slide through. Instruction guide was very helpful with only some minor differences, but it is pretty obvious what to do once you get into it.



by:

First, the packaging is first rate - super-heavy duty cardboard box, stapled together, not taped! Filled w/industrial grade packing paper - lots of it! Way to go, Shipping!!! Secondly, after thoroughly reading the Installation Instructions before dinner this evening, I decided that at 76 years old, maybe I should drive down to my Chevy Dealer and have a chat with my Service Manager about an after-market, add-on job!!! Looks a bit too involved for me (these days, anyway)!



by:

This was instilled on a 2024 Chevrolet Colorado Z71 truck. I watched your video online with this exact model truck and the words I remember most was “and we did not have to do any trimming”. Well my truck was certainly different than what was on video. Guess it’s because it’s a late build 2024 (end of September 2024) and the grill system was maybe what would appear on the 2025 models? There was lots of trimming involved. I also will tell you the mounting holes both for the frame and the bumper back plate did not line up and required some modifications to fit. I would like to say this job is not for the faint of heart. I luckily have a mechanical/machinist background so was able to get the job done. Have not tested it yet but will be soon. Good luck to those of you who are planning on installing it yourself. Just remember it can be done. Just take your time.



by:

Items arrived in 2 days, free shipping. All appeared in new undamaged condition.



by:

Well built and relatively easy to put on. I have a 2020 Jeep Mojave, and there was an issue with leaving my skim plate on the bottom. There were some existing bolts that wouldn't allow the base plate to sit if the remained. After watching the video and reading paper instructions, the bolts weren't addressed. It was a non - issue since zi dont need the skim guard.



by:

The Blue Ox base plate for my 2015 Kia Soul is well manufactured and, with a little bit of mechanical skill, easy to install. It fit perfectly without issues. Brad from etrailer provides a step-by-step installation video that is outstanding and nicely guides through the process from beginning to end. I highly recommend this Blue Ox base plate from etrailer.



by:

Well the blue ox base plate actually fits my turbo engine. The Curt didn't fit as advertised.



by:

Super high quality baseplate for towing by Blue Ox. Instructions, videos, shipping (one day!) and overall experience was awesome. A bit pricey but their quality and the additional support by E Trailer cannot be beat! BTW (E Trailer) the baseplate fits three different Jeep configurations but did not call out the Recon package. After looking at other brands which showed there's to fit the 3 variations AND the Recon, I figured it would fit and it DID. You should definitely upgrade to include the Recon Edition.



by:

I got a used set for a great price and it worked out well. my only caution is that some of the holes in my 2008 2500 suburban had to be drilled to 9/16 due to misalignment with the tapped holes in the brackets. This minor adjustment made it all go togehter easily though. Be aware, you won't have tow hooks anymore if that is something you use a lot.



by:

lways great to shop at etrailer, especially the tech experts. Royce did an awesome job with our order. Everything fit perfectly and the help video provided the guidance I needed.

We installed the baseplate on our 2023 Encore GX AWD as well as the light harness and breakaway switch. A couple of items were incorrect but Royce corrected the issues with no problems.

Thanks again etrailer!



by:

2019 Ford Ranger baseplate worked and fitted fine for me. 73 yrs old took me a couple hours but took many breaks. Younger could do it less than hour I'm sure.
Also works fine with my Blue Ox tow bar.



by:

I looked into every brand/model available and this was the beefiest. There is cutting and trimming required on all brands, so why not get the strongest? If you're slightly handy with a toolbox, you can easily do the install yourself and save thousands.



by:

Great price, fast delivery.

  • Looking For Install Video For Base Plate On 2010 Toyota Yaris
    Hey Nigel, thanks for reaching out. I do have some resources I think you will find helpful, but we haven't had a chance to install the Blue Ox base plate # BX3780 here at our shop yet, so no chance to shoot a video for a Toyota Yaris. That said, we did install the Roadmaster brand base plate on a 2013 Yaris, and we shot a video of that install. So not exactly the same base plate, but the process is somewhat similar, so that video should give you a good enough idea of what you're in for....

  • Why Won't Blue Ox BX3780 Fit 2008 Yaris Sedan S
    Hi Craig; when I reached out to Blue Ox they said the trim and frame doesn't allow their # BX3780 to fit on the S. I have my doubts about the frame difference but it is pretty standard for the trim to be the issue. More than likely if you tried to install it you would have to cut up the front fascia in a way that would look terrible. Sticking with the Demco # DM9517213 is your best option. I'm assuming you're using a Blue Ox tow bar so you will also need the Blue Ox Tow Bar Adapter Brackets...

  • Which Blue Ox Base Plate Kit Fits 2007 Toyota Yaris
    Hey Steve, I don't have the ability to look at your shopping cart but the Blue Ox base plate kit part # BX3783 is correct if you have a hatch back model or part # BX3780 for if you have a sedan. I assume the Blue Ox tow bar part # BX4330 is what you are considering as well since it's part you referenced? If so, then yes this would work for you. The rest of the parts I am not sure of what you have so I would need you to let me know and I can check for you.
