Features to know about

Made for a Clean Front End: Hidden Base Plate with Removable Arms

If you want your setup to keep a clean, factory look when you’re not towing, this base plate makes it easy. The hidden design keeps brackets from sticking past the front end, and the removable arms come out with a simple twist. When the arms are off, plug in the included receiver covers to block dirt and debris while keeping everything looking finished.

Blue Ox base plate kit installed on vehicle front with removable arms attached, showing clean hidden design for flat towing.

Hook Up Fast and Secure: Twist-Lock Arm System

Connecting your tow bar doesn’t need to be complicated. Each arm slides into the receiver, twists until it locks in place, and secures with a pull pin. When you’re done towing, pull the pin, rotate the arms, and lift them out. It’s quick, solid, and repeatable—an easy way to line up and lock in without wrestling with tools or tight clearances.

Built Strong for Long Miles: Bolt-On Steel Construction

This base plate bolts directly to your chassis using the included hardware. The sturdy steel build spreads towing forces evenly across the frame to help prevent stress on your suspension. There’s no welding required, and the powder-coated finish resists rust and corrosion so the setup stays reliable through miles of travel.

Keep Your Setup Flexible: Works with Multiple Tow Bars

Whether you already have a tow bar or are starting fresh, this base plate fits right in. It pairs directly with Blue Ox tow bars for a secure connection. It’s also adaptable for use with Roadmaster tow bars using adapter RM-031 or RM-031-5 (sold separately), or Demco tow bars using adapter DM9523041 (sold separately). Integrated mounting points make it easy to add an electrical connector plug bracket if needed.

Sized Right for Planning Your Setup: Bracket Spacing and Height

The distance between brackets is 25" and bracket height is 16", giving you solid reference points for matching up your tow bar height or planning accessories like wiring harnesses and safety cables.

This is a first class company, from who you talk with when needing information, through the order process and then the packaging and delivery. They did everything they said they would, the first time. No issue at all. Why try someone else when this is all you need, call them!!

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.

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!

Not really, I grew up in Chicago, basically 45+ years. I have been to Wrigley many times as a child and adult. We lived about 1 mile from the park. Going to see my mom who is 95 years old. Our favorite place to visit in Chicago is Navy Pier. We try to make a day of it. Thanks for asking! EdnJudy

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.

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

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.

I am glad you were able to get it installed with no issues and a little help from our video! What kind of coach are you pulling the Kia Soul with?

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.

Still the same no issues...fine product

I installed this myself on a 2012 CR-V EXL AWD. The directions are straightforward. The system works very well and is easy to use.
Fair warning .. because the car is older, just about every clip that holds the grill and bumper in place broke when taking them off. Replacing all those clips with OEM parts is expensive!
BUT, that doesn't retract from the quality of the baseplate or it's use ability.
This is the third different Blue Ox baseplate system I have bought and installed and all of them were excellent!

Its been two years since installation of the Blue Ox Baseplate. Since then, Ive flat towed the CRV from NJ to FL and back three separate times with many other shorter trips in between. Paired with a Blue Ox Tow Bar, the system has worked flawlessly since installation.

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

Thanks for the detailed review Chris, and the pointers! This will be most helpful to others. What was your favorite stop in those 7,000 miles? Where did you go, what did you see?

by:
2008 Ram 2500
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.

Follow up. Ive put about 8000 miles on the setup and its been great. A 34 ton suburban pulls nicely behind my Dutch star, and they dont have a steering lock so its nice not to have to retrieve keys when stopping for the night. I have used the safety cable attachment a few times for straight line pulls with a small shackle when working as a rally racing volunteer, its been fine but I wouldnt side pull on it.

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.

Great products from etrailer. The videos were very helpful as I was determined to do the install myself. I’m 72 years old and thought I could do it and I did with the help of my lovely assistant, my wife. The tip on running the taillight wiring through the frame rail was great. The one problem I had was that I was never able to unplug the taillights no matter how hard I tugged on them so I had my wife hold each light while I spliced in the diodes. Very happy with the Blue Ox products and the finished look on my Jeep. Thanks again etrailer.

It's a great system, it's on a 1998 Holiday Rambler Imperial, pulling a 2012 Ford F150 4x4. Last summer I pulled the truck for over 3000 miles without any problems, didn't feel like the truck was behind me. etrailer did me right on this set up.

Not for the impatient, but everything is provided. I had the front end of my Jetta all over the lawn. It’s definitely a 2 day job, but the instructions are thorough.

Review is more about e-Trailer than a the Blue ox tow system! (Which was fine) I contacted trailer in a panic after an amazon seller cancelled my order for this same product after 6 weeks of waiting! Etrailer, had the product to me in Canada in 4 days of the call! Awesome!
by:
Strong and quality product. Installation was not hard, but follow the steps and look at the video as the written instructions are not all clear and miss a few templates for the air duct cut/trim out. I found the trimming needed for the bottom grill was minimal, only required for the round pieces that the adapter inserts into. Overall, an excellent product, good quality.

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.

  • Can I Use A Diode Kit On A 2024 Lincoln Nautilus
    Hello Dennis. There is not a lot of information out there on the 2024 Lincoln Nautilus as far as flat tow wiring. Based on what I can find online, a diode kit cannot be used on a 2024 Nautilus. The only approved solution for brake lights at this time are magnetic tow lights such as the Demco LED Light Bar for Towed Vehicles # DM36MV, which is what I recommend.

    Hi Barry; the only base plate kit for the 2024/25 Nautilus is the Blue Ox Base Plate Kit # BLU35UR which is designed to fit the hybrid model. According to the owner's manual, you cannot flat tow your Nautilus unless it is the hybrid. If you have the regular gas engine model the only option is to use a trailer. Assuming you have the hybrid I recommend the following for a complete setup: -Blue Ox Base Plate Kit # BLU35UR -Blue Ox Avail Non-Binding Tow Bar # BX7420 (includes safety cables) -Roadmaster...
