Features to know about

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

When you’re not towing, this setup keeps the front of your vehicle looking stock. The hidden design keeps brackets tucked away and out of sight, while the removable arms twist out quickly when you’re done towing. Receiver covers plug into the openings to keep dirt and debris out and give the base plate a finished appearance. No bulky hardware sticks out past the bumper, so there’s nothing to bump your leg on when walking by.

Hook Up Fast, Even When You’re Solo: Twist-Lock Arms with Pin Release

Connecting your tow bar is simple—insert each arm into the base plate’s receivers, twist until they lock, and secure them with the pin. When you’re ready to disconnect, just pull the pin, rotate, and slide the arms out. It’s an easy process that works even when you’re setting up on your own. The distance between brackets is 22" and the bracket height is 15-1/2", giving you consistent connection points every time.

Built to Take Miles: Durable Steel Construction That Spreads the Load

This base plate bolts directly to your chassis with included mounting hardware—no welding required. The sturdy steel design spreads towing forces evenly across the frame to help prevent stress on suspension components during long hauls. Its powder-coated finish resists rust and corrosion, so you can rely on it through years of use and thousands of miles of towing.

Keep Your Setup Flexible: Works with Multiple Tow Bars and Accessories

Already have a tow bar you trust? This kit pairs directly with Blue Ox tow bars for a secure connection, no adapter needed. 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). Integrated mounting points make it easy to attach an electrical connector plug bracket (sold separately) so your wiring stays neat and accessible.

Installation was fairly straightforward. Only thing I would add the video doesn’t mention. The hole that needs to be drilled on passenger side. I put a piece of 1x4 wood between the radiator hose and the frame when I was drilling as the hose is pretty close to the frame and could be damaged if you drill too deep. I also put the bolt heads inside engine bay with the threads sticking to roadside as I felt again to close to radiator hose. I removed washer bottle completely to give easier access.
I wasn’t real happy about how much bumper I had to trim . The activ model has a different bumper c er than the RS. The studs for mounting wiring connector wound up really gut under the tag bracket so that was a win.
The bracket seems heavy duty and well made . Follow directions in the etrailer video. Very simple install. Drilling the hole was the hardest part.



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.

The 2025 Trax license plate frame sits lower than shown in the instructions provided with this kit, to the point where it obstructs access to the 7-way electrical connector. An alternate scheme for mounting the plate will be required if your state requires the front plate to be displayed.



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!

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:

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.

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:

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:

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).

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.

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:

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!

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.

Since the battery gets disconnected you would need an outlet kit part # RM-9332 to power the supplemental braking system. The automatic transmission Sparks have to be towed on a dolly like the Roadmaster Tow Dolly # RM-2050-1. For a base plate...
