Features to know about

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

When you’re not towing, the hidden design of this base plate keeps the front of your vehicle looking clean and factory-finished. The brackets stay tucked away behind the fascia, and the removable arms come off with a quick twist. Once removed, plug in the included receiver covers to keep dirt and debris out and maintain that finished look. No bulky metal sticking out, no risk of catching your leg on anything.

Quick Hookups Anywhere: Twist-Lock Arms that Secure with a Pin

Connecting up is straightforward thanks to the twist-lock attachment system. Each arm slides into its receiver, rotates into place, and locks in with a simple pin pull. The process is quick whether you’re parked on level ground or uneven terrain. It’s a sturdy setup with bracket spacing of 20-1/2" and a bracket height of 12", so matching your tow bar height is simple.

Solid Connection You Can Trust: Steel Construction That Spreads the Load

This base plate bolts directly to your chassis—no welding required—and uses durable steel that’s powder coated to resist rust and corrosion. The design spreads towing forces evenly across the mounting points to help reduce stress on your suspension. The included hardware ensures a solid, reliable connection that stands up over long miles of towing.

Keep Your Setup Flexible: Works with Popular Tow Bars and Adapters

You can pair this base plate with Blue Ox tow bars for a direct match or use it with other brands through their dedicated adapters—Roadmaster adapter (RM-031 or RM-031-5) or Demco adapter (DM9523041), each sold separately. Integrated mounting points make it easy to attach an electrical connector plug bracket so your wiring stays neat and ready to connect when you hook up.

DIY-Friendly Install: Straightforward Bolt-On Mounting

For those who like to handle their own projects, this kit keeps things manageable. It mounts securely using included hardware and lines up directly to factory chassis points, so there’s no welding involved. With patience and standard tools, you can get it bolted up cleanly and ready for the road by the weekend.

Excellent Product. Heavy Duty. You can install it if you have basic skills. After complete, we took our 2017 Subaru CrossTrek on a 6000 mile cross country tow. Worked great!

2016 Subaru Impreza

Ranking above has nothing to do with etrailer who I have used for may items and had no issue.

Installed on a 2016 Subaru Impreza, Third Blue ox tow bracket I have installed on a Subaru.

Instructions are fair, web site with colored pictures helps, although they could have some more detail on pieces to be cut or trimmed would help.

Biggest issue was the reinstall of the bumper. I had to do some major removal of the rear of the fog lights plastic support before i could fit the bumper correctly.

I felt that this was a design issue with the tow bracket design.

It fit may new 2015 Subaru Crosstrek XV Toad as advertised. It has been an excellent addition for towing my auto behind my motorhome.

by: Rick 01/04/2020 One Year Later

Finish of the base plate was excellent. The unit would get five stars if I didn’t have to notch the frame flanges to install it. After careful torquing on the install, I have a solid install after 8,000 miles of towing.

This Blue Ox Base Plate Kit for my Subaru Crosstrek was in stock and delivered next day. Blue Ox told my dealer they could get the Base Plate kit build and sent to them in 12 weeks. I got this base plate in one day.
I'm very pleased with etrailer.com and their parts availability.

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!

@EdV That sounds awesome. Utah is beautiful. Chicago is probably one of my favorite places to visit. Are you going to check out Wrigley?

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

2017 Jeep Wrangler

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.

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.

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

by: Matthew 10/07/2025 One Year Later

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.

2013 mini Cooper

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: Perry 09/24/2025

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.

Perry One Year Later

10/1/2026

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: Vertical Caver 12/06/2025

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.
