Features to know about

Clean Front End, No Bulky Hardware: Hidden Crossbar-Style Design

When you’re not towing, you’ll barely notice this setup. The hidden bracket design keeps the front of your vehicle looking clean and uncluttered, with the brackets tucked away inside the grille for protection from scrapes and scuffs. Once the drawbars are removed, the remaining brackets are virtually invisible, giving you a factory-style appearance without any exposed hardware.

Quick Hookups Without Hassle: Twist-Lock Removable Arms

Connecting and disconnecting is simple thanks to the twist-lock system. Just insert each drawbar, twist to lock it in place, and you’re ready to go—no pins or clips required. When it’s time to unhook, twist again and pull them out. It’s a straightforward setup that makes towing easier whether you’re at home or on the road.

Strength That Lasts: All-Steel, Computer-Cut Construction

Built from computer-cut, all-steel components, this base plate kit is made to handle long-distance towing with confidence. The black powder coat finish provides extra durability and corrosion resistance so it stays in good shape through years of use. The sturdy frame-mount installation helps distribute towing forces evenly for reliable performance trip after trip.

Straightforward Install You Can Tackle: Bolt-On Fit with Included Hardware

No welding is needed here—just bolt it up using the included mounting hardware and clear instructions. The custom-fit design lines up with your vehicle’s frame for an accurate fit, making it a solid weekend install for someone who likes to handle their own projects. Once installed, it’s ready to pair with Roadmaster tow bars using a quick-disconnect crossbar (910021-00, sold separately).

First of all, thank you etrailer for getting the Baseplate Kit for my Chevy Spark to me in time for my trip. Everything I needed was in the box. The step by step instructions were very easy to follow. I would definitely take their suggestion to read and understand the instructions before beginning the job. That step allowed me to always know what was coming next. Several holes need to be drilled, no problem with location, it is all in the instructions. Be sure to have good sharp bits. The whole process is an easy bolt on. I work slowly and got it done in one afternoon. At the end, after installing the baseplate, when you put the front facia back on the car, they suggest leaving off the Styrofoam inner bumper but I found no need to do that as it still fit right back on no problem. It would be up to you to leave it off or not. I thought it would be safer with it on there as was the original. In the end I added a light kit with a 4 round plug on the front. Very well thought out for Roadmaster to supply a place to mount the receptacle. Thanks again, I can now leave on time and take my car with me.

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.

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.

Thanks for the review and for sharing your installation experience Christian. Your tip about leaving the bumper on during install is really helpful, especially since fitting the ends through the louvers can take a little extra maneuvering. It’s also great to hear the setup works well with your Stowmaster 5000. The install looks great, and we appreciate you sharing the picture! Where did you go for the first trip?

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

Everything related to my Mini towing system is working great after a year of use.i do wish I had bought a cover for the tow bar though. Keeping it clean would be easier with the cover. Great products and service from etrailet

2007 honda Element

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!

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.

New system working fine. As with previous system it requires towed vehicle to be nearly perfectly aligned straight behind motorhome to disconnect without considerable tension.

by: David 05/23/2025

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: Steven 08/09/2026

Overall the installation was great, however the process of drilling 3 - 1/2" holes in that little bumper that has a Rockwell Hardness of about 60, seems to be a bit over the top.The instructions are spot on, delivery was great, the quality of product was accurate. I am a happy boy!

Fit and finish is great, the illustration for what you trim on the bumper isn't great but otherwise pretty easy install (I ended up measuring between the mounts on the draw bar and just trimmed accordingly)

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.

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.

Install pretty easy. You will have to change directions of one bolt due to obstruction ( frame). Cannot torque a few of the bolts. These are the ones with wire attached.
Rock guard needed addition trimming from factory instructions.

Parts Needed to Flat Tow a 2014 Chevy Spark 1LS with Manual Transmission
I spoke with my contact at Roadmaster and the base plates # 523174-1 will fit your 2014 Chevy Spark 1LS with manual transmission. For a compatible tow bar I recommend the Falcon 2, # RM-520.

Why Does the Key Need to be Turned to ACC/ACCESSORY When Flat Towing a 2014 Chevy Spark
The reason that you need to turn the key to ACC/ACCESSORY when flat towing your 2014 Chevrolet Spark is so that the steering wheel will be unlocked. Otherwise the steering wheel will be locked and you will ruin your vehicle. It will cause your battery to slowly drain, but you can install a Roadmaster Battery Charge Line Kit # RM-156-25 on your Spark to help maintain the battery charge level while it is being flat towed. You can run the wire from the charge line kit to the center pin of...
