Features to know about

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

If you like a clean, factory look when you’re not towing, this setup keeps things tidy. The hidden design leaves nothing bulky or awkward sticking out from the front. The removable arms twist out easily, and the included receiver covers plug in to keep dirt and debris out while giving a finished look. You get a smooth front end with no exposed brackets or protrusions to bump into when walking by.

Quick Hookup Every Time: Twist-Lock Attachment System

Connecting your tow bar is quick and straightforward thanks to the twist-lock arms. Each arm slides into the receiver, rotates until it locks in place, and secures with the pin. When you’re done towing, pull the pin, give it a twist, and the arm comes right out. It’s a simple, secure system that makes setup easy whether you’re at home or on the road.

Strong Where It Counts: Durable Steel Construction That Spreads the Load

This base plate bolts directly to the chassis with no welding required. The sturdy steel construction spreads towing forces evenly across the frame to help prevent stress on your suspension components. The powder-coat finish resists rust and corrosion for long-term reliability through cross-country miles and varying weather conditions.

Ready for Your Setup: Compatible with Blue Ox Tow Bars and More

The sturdy lugs pair perfectly with Blue Ox tow bars for a solid connection every time. If you have a Roadmaster or Demco setup, adapters are available separately (RM-031, RM-031-5, or DM9523041). Integrated mounting points also let you add an electrical connector plug bracket (sold separately) so your wiring can be neatly installed right where you need it.

Straightforward Install: Bolt-On Design with Included Hardware

This kit is designed for a direct bolt-on installation—no welding needed. It secures firmly to your vehicle’s chassis using the supplied mounting hardware for a solid fit. With bracket spacing of 20" and a bracket height of 14", it’s built for balanced alignment within your towing setup and dependable performance trip after trip.

Instructions could have been better but was straight forward and easy to figure out. Had to widen two holes on vehicle a tiny bit to align up with plate. Was shorted two connectors to attach the safety cables to the vehicle and base plate. None mentioned on inventory but two were included. Picture showed using four.



by:

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.



by:

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:

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:

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.



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).



by:

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.

Items arrived in 2 days, free shipping. All appeared in new undamaged condition.

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.

I needed a receiver for a Jetta, other companies did not have it in stock. Etrailer had it in stock and said that they would ship in the morning, which they did. I got it 4 days later, counting sunday and the 4th of July! Very helpful, and great on the phone.
Great work!

  • Equipment Needed to Flat Tow 2014 Volkswagen Jetta
    If your Jetta is a non-hybrid model and has the 5 speed manual transmission, it is capable be being flat towed. The automatic and 6 speed manual need to be towed on a tow dolly like # RM-2050-1, according to my research. If you can tow your particular vehicle, you'll need base plates, safety cables, a tow bar, a wiring harness, a supplemental braking system and possibly a high/low adapter. For base plates, use # 521236-1 and # RM-643 safety cables. For a tow bar, I'd recommend an all-terrain...

  • Parts Needed to Flat Tow a 2012 Volkswagen Jetta with 2.0 Liter Gas Motor Behind an RV
    Roadmaster lists base plates # 521236-1 for the 2.5 liter gas motor and 2.0 liter diesel motors of the 2012 Volkswagen Jetta but does not include any of the other 8 motor options for this vehicle. What I recommend is the Blue Ox base plates # BX3831 because they fit all models except the 2.5 liter models. For a compatible tow bar I recommend the Alpha, # BX7380. This tow bar is rated for 6,500 pounds and comes with safety cables so you will not have to buy any separately. I have linked...

  • Can a 2015 VW Jetta 1.8 CL Be Flat towed
    While many vehicles will have base plates and other components available, only some trim levels are able to be safely flat towed. The OEM is final word on what conditions are needed and what trim levels can be safely towed. We always recommend that you review your vehicle specific owners manual for this information as the OEM is the authority on if a vehicle they manufactured can be safely towed and how.

  • Recommendations for Towing a 2012 Volkswagen Jetta 5-Speed Manual
    Your 2012 Volkswagen Jetta 5 speed manual is towable, but it is not recommended to tow at over 65 mph according to the manufacturer and should be started every so often and run for 5 minutes to prevent battery drain. If you are interested in a complete flat towing system for this 2012 VW Jetta, I'd be happy to assist with some recommendations.

  • Base Plate and Tow Bar Kit that Fits 2014 Volkswagen Jetta
    The tow bar part numbers you mentioned is a Haulmaster tow bar which we do not offer any base plate kits that are compatible with that so our best option would be a base plate kit like the Blue Ox # BX3831 which you could use with a Blue Ox tow bar like the part # BX7420. We do not have a way to use a Haulmaster tow bar with any of our base plate kits.
