Features to know about

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

This base plate keeps your front end looking clean when you’re not towing. Its hidden design means the brackets won’t protrude past the front of your vehicle, and the removable arms leave a seamless look once they’re off. When you’re done towing, plug in the included receiver covers to keep dirt and debris out of the base plate and maintain that finished appearance.

Quick to Attach and Remove: Twist-Lock System with Pin Securement

Hooking up is simple with the twist-lock design. Each arm slides into the receiver, rotates until it locks, and secures with a pull pin—no tools or complicated steps needed. When you’re unhooked, just release the pin, twist to disengage, and remove the arms. It’s quick, clean, and perfect for those who don’t want extra hardware sticking out when driving around town.

Strong Where It Counts: Steel Construction with Even Force Distribution

This base plate bolts directly to your chassis, so no welding is required. The sturdy steel design spreads towing force evenly to prevent stress on your suspension, helping everything stay aligned and secure over long miles. A powder-coated finish resists rust and corrosion, keeping it looking sharp year after year.

Set Up for Your Tow Bar: Secure Lugs and Adapter Compatibility

With its strong lugs, this kit pairs directly with Blue Ox tow bars to create a reliable connection. It’s also adaptable for use with Roadmaster tow bars using adapter RM-031 or RM-031-5 (sold separately), and with Demco tow bars using adapter DM9523041 (sold separately). The integrated mounting points make it easy to attach an electrical connector plug bracket if you want to tidy up your wiring.

DIY Friendly: Bolt-On Installation with Included Hardware

No welding or fabrication needed here—just bolt it on using the included mounting hardware. The straightforward installation design makes it approachable for hands-on owners who prefer to do their own setup. Specs are clear too: distance between brackets is 18" and bracket height is 12-1/2". Once it’s on, you’ve got a solid, reliable connection ready for the road.

How I like my Blue Ox Base Plate Kit for a Scion xb after owning it for a year. I have towed the xb from Virginia to Florida and back. Than Virginia to Niagara Falls, throw Canada to Michigan, and beyond to Minnesota and back to Virginia. I have had much success.

My perspective, looking back, I would purchase the Roadmaster base plate because it is much, much easier to install. The Blue Ox brand had me drill 8 or 10 holes in the car frame. The Roadmaster installs without drilling.

I did install the Blue Ox base plate. I like it and will continue to use it to flat tow my Scion xb.

In addition, I also installed a 30mm lift kit in the front of the Scion xb. The car rides way to low as a standard set up.

It is a must to install a RVi towed battery charger to keep the towed car battery charged. I use a Patriot 2 braking system.

The item I received must have been a returned item. The box label was proof it was shipped to someone else before. Reason I'm not happy is because the bag of screws was open and most of it slipped out of the holes of the damaged box that was opened before and re-taped. The end of the crossbar was bent and not much packing inside. I needed this for our trip, so I didn't return it and had to fix and find screws to make it all work.

I am sorry that your order arrived in this condition. I can assure you that we do not sell returned or used product. However, we do have a demo and install team that will use the product to put content on our website. It is possible that the packaging was not put back together properly.

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.

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.

Thanks Douglas, nice truck you've got there! Nice job on the install.....

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.
by:
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.

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

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.
by:
Very nice trailer.

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.
