Features to know about

Made for a Clean Front End: Hidden Design with Removable Arms

If you want a towing setup that disappears when you’re not using it, this base plate delivers exactly that. The completely hidden design keeps the front end looking clean—no bulky brackets or crossbars sticking out. When you’re done towing, just twist and pull to remove the arms, then pop in the receiver covers to keep dirt and debris out while maintaining a finished look.

Hook Up and Go: Twist-Lock Arms for Quick Connection

The removable arms use a simple twist-lock attachment that makes connecting fast and secure. Slide each arm into the receiver, rotate until it locks, and secure it with the pin. When you’re ready to unhook, pull the pin, twist, and remove. It’s straightforward and easy to handle whether you’re setting up at home or on the road.

Built for Strength: Steel Construction That Spreads the Load

This base plate bolts directly to your chassis with no welding required. The durable steel construction is powder coated to resist rust and corrosion, while its sturdy design spreads towing force evenly to help prevent stress on your suspension. The brackets won’t protrude past the front of your vehicle, so everything stays solid and streamlined mile after mile.

Works with Your Tow Setup: Broad Adapter Compatibility

No need to overhaul your existing gear—this kit pairs directly with Blue Ox tow bars through sturdy lugs that form a reliable connection. It’s also adaptable for use with Roadmaster tow bars using adapter RM-031 or RM-031-5 (sold separately) or with Demco tow bars using adapter DM9523041 (sold separately). Integrated mounting points make it easy to attach an electrical connector plug bracket (sold separately) right where you need it.

Straightforward Install: Bolt-On Fit with Included Hardware

You don’t need a welder for this one—just standard tools and some time. The base plate bolts securely to the chassis using the included mounting hardware for a solid fit. The setup is designed for straightforward installation so you can get everything aligned properly and ready for your first flat-tow trip without extra fabrication work.

All went well with the installation except I could not use the nuts with the welded wire. The wire was way too stiff for me and I had trouble aligning the nut with the bolts. I ended up cutting off the wires and aligning the nuts to the bolts with my fingers.

Works just like it’s supposed to. Haven’t had any problems with it. Easy to hook up and unhook.

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.

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.

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.

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:

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.

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.

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.

2015 Ford Fiesta
So here is an honest review of the Blue Ox base plate. I ordered this base plate because I already have a Blue Ox tow bar. After watching the video of the Ford Fiesta install it didn't look too bad. In the video of the guy suggest ordering a different brand and after the install I understand why. Taking apart the front end of the car is easy the problem lies in the way Blue Ox decided to use welded nuts on bendable rods it is very difficult to get these aligned after drilling the holes. My advice for anyone who's going to do this is be prepared and have patience. After removing the headlights in front fascia cut out the edges of the plastic as noted in the video and then Mount the bar measure the half inch gap on one side and put a clamp on it. Here's where it gets annoying instead of just putting holes in it using a drill bit that would be in any 10 to 15 piece drill index they decided to use a 13/32 bit which you will only find in large quantity indexes. Here's what I found makes this job easier after drilling the first two holes in the base plate install the top bolt only and then tighten it down if you do both you're going to have two wires hindering your movement when you go to do the rear plates. Same thing when drilling the hole in the rear plate put the top bolt in first and this leaves you more room to work with. Prepare to be frustrated the system they use was not thought out very well there was plenty of room to drill all the way through to the other side of the frame and use a through bolt to simplify this whole process. It probably would have cost him a few more dollars to get larger bolts whatever the reason was this system of nuts welded the wires is nothing but a headache. Once you get past this point and it's time to install the safety cables in the video it shows him just wrapping around the rear side of the backing frame the cables in this kit are far too long to be of any use if the front bumper disconnects the way the cables are routed they can slip around the Mainframe there's enough slack that you can actually wrap it around the inside of the base plate mounting attachments to take up the slack. Other than the method of installing this the bar itself is well built. Getting the bumper put back on and cut out for the attachment points is tricky to say the least I ended up cutting out a little bit too much of the grill but I may just order another Grill now that I know exactly where it ends up when it's fully mounted. I would imagine it cost quite a bit to have one of these installed as what could be a straightforward install takes several extra hours of fighting alignment of the nuts on a wire system. Want thank e-trailer as they have the best price and it was shipped in a timely manner.
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.

The Acclaim connects directly to the removable arms on the Blue Ox base plates, so you won’t need an additional adapter between the two.
