Features to know about

Made for a Clean Look: Hidden Bracket Design with Removable Arms

If you like a setup that doesn’t clutter your front end, this base plate kit keeps everything tucked away. The hidden bracket design sits far back in the grille, leaving nothing visible once the drawbars are removed. When you’re not towing, the remaining brackets are virtually invisible and protected from scrapes and scuffs. It’s a neat, low-profile look that keeps your setup clean and out of sight.

Hook Up and Unhook Without Hassle: Twist-Lock Removable Arms

Connecting your tow bar is quick and simple with the twist-lock system. Just insert the drawbars into the brackets, twist to lock them in place, and you’re ready to go. Built-in pull rings let you unlock the arms so you can twist and remove them when you’re done. The design makes attaching or disconnecting easy to do solo, with no tools or pins to fumble with.

Built to Last: All-Steel Construction with Black Powder Coat Finish

The computer-cut, all-steel construction gives this kit serious strength for long-term towing use. Each bracket is precision made to fit perfectly and spread load evenly across the frame. The black powder coat finish adds a layer of corrosion resistance while keeping things looking sharp after miles of road time.

Fit and Function in One Package: Custom Mounts and Integrated Attachment Points

This base plate kit bolts directly to your vehicle’s frame—no welding required—and comes with instructions and mounting hardware for a straightforward install. Integrated mounting points let you attach an electrical connector plug or bracket (sold separately) right where you need it. It’s also compatible with Roadmaster tow bars when used with the quick-disconnect crossbar (910021-00, sold separately), making it easy to tie into your existing towing setup.

by:

We towed our 2004 Subaru Impreza WRX STI 3000 miles last year, this is an ideal setup, discreet when not in use, solid, and easy to get on/off. Very please with the support I received from Roadmaster as one of the bolt was missing, was sent super quickly.



by:

Not an easy install on a Trax but it is very well made and gives a clean look. I did customize by cutting down the 6 pin bracket supports to get it flush with front of the car.



by:

Awesome delivery speed, and a well made base plate for my 2007 Element. Installation was a breeze (thanks to my son’s heated shop) and I had to do no cutting to make this fit. I had a Stowmaster tow bar that came with my RV and etrailer was able to steer me to the correct missing parts to make this a really affordable installation. Now to get out of this snow!



by:

Purchased for a 1997 Subaru Impreza. Delivery was amazingly fast! I didn't have it installed until a few months later, as my travel plans had stalled. It didn't quite bolt right on, but was close, and a friend had to modify it some to make it work. I still hear a grating noise when I turn too sharp on one side, but otherwise it's fine.
The front connection plates didn't line up with the holes, so had to have those modified, as well, in order to line up and attach to the tow bar. Once the new holes were drilled, I was able to hook up and go.
It's relatively easy to connect after finding a way to do it alone.
I've towed from CO to TX and all over TX with it with no problems.



by:

After ordering the wrong crossbar, etrailer sent the correct one for our Mini Cooper quickly. However I did have to modify most of the holes as the cross bar didn’t quite fit (but close). I had to drill the three main bolt holes to 11/16 so that the bar would go over the Mini’s 3 main bumper bolts on both sides. The two lower bolt holes (each side), needed to be drilled out 3 sizes larger to accommodate the 4 bolts that come with the kit. I had to drill out the Minis lower holes to better align with the crossbars lower holes. I would also like to note it being a pain in the knuckles to reach one of the three (each side) bolts to put the stock nuts on the bolt and then try and get them tight. (The main bolt pattern for the upper bumper is diamond shape, one up tow bolts lower. (The lower “inside” bolt on each side is the one that is hard to get to and tighten.) Sorry I didn’t get picks, I was in a rush to get the car back together. There’s an angle piece on the cross bar that blocks the hard to reach bolt, it would be helpful if that could be made more accessible to reach.

I’ve been purchasing products from ETrailer since 2005 and all the products I’ve purchased have been a great value. The products mentioned above installed perfectly and with the direct assistance from ETrailer everything fit as suggested. I will always interact with ETrailer as needs present themselves.



by:

Replaced same part that was damaged in a crash. I had used my original one for close to ten years without issue. Fast shipping from etrailer.



by:

The Base plate kit is well made and came with all the necessary hardware.Installation is relatively straight forward. I did have to enlarge two of the holes that didn't quite line up. But overall I'd recommend it.



by:

Bolted right up. Installation should be done with bumper on, as you can't fit the ends through the louvers without some convincing. Works great so far. Was able to use a Stowmaster 5000 with it.



by:

Installation was a bit trying. Ended up looking very clean and almost invisible.
Using the tow bar worked super easy and our motorhome hardly noticed the Mini Cooper back there.



by:

Came quickly and is very high quality. Great directions/video from road master makes the installation step by step easy to follow.
Skill level is probably at the intermediate level depending on experience.



by:

The #118-3 is a perfect fit on my 1995 Geo Tracker. When you pull off the removable arms you would never know they are there. The Quality is very good easy to put on all you have to do is drill 4 holes the tube on the base plate fits into the tube on the frame of the tracker and with the 2 bolts it is a solid fit. I was worried about the plate nut getting it inside of the frame but it went in easy when you put it over the frame tube and use a thin piece of metal to slide it in place. I’m very happy with it. I probably could of got it on without taking my bumper off but with only 4 bolts holding my bumper on it made it easier

You all did a great job getting the parts here. Thank you



by:

Good solid construction. A lot of work to install and some trimming required to make it fit behind the grill, but was able to install it myself. And it looks good since most of it is hidden behind the grill.



by:

Works ok, but I’m not happy it required removal of 1/3 of the radiator shutters.



by:

Easy to use. Makes hooking up to our Class C RV simple and quick



by:

Great product. Had base plate and Air Force One professionally installed. Easy 3 minute setup to flat tow behind motorhome.



by:

Item arrived as stated plan on installing it this coming weekend As the sight indicates this is not confirmed to fit the 2025 Ford Maverick, I will follow-up after I have installed it.



by:

It is a complex install, but worth it. Barely visible. I would have liked wiring instructions for lights. Used it to tow my Maverick from Los Angeles to Oregon and back. It has a bracket for a 4 pin connector but I used a seven blade connector and had to attach it to the grill.

  • Base Plate Kit Recommendation for 2023 Ford Maverick with Blue Ox Tow Bar
    For you I would recommend sticking with the Blue Ox base plate kit part # BLU88XR that fits your 2023 Ford Maverick. Mainly because you already have a Blue Ox tow bar which means you would not need to use any adapters but also because in general the Blue Ox base plate kits are easier to use so I like them better.
