Features to know about

Made for a Clean Front End: Hidden Bracket Design with Removable Drawbars

This kit keeps your front end looking clean when you’re not towing. The hidden bracket design mounts within the grille, leaving the hardware protected and almost invisible once the drawbars are removed. With no bulky crossbar showing, the vehicle keeps its original look, and there’s nothing sticking out to bump into when walking around it.

Hook Up Fast and Simple: EZ Twistlock, No Pins or Clips Needed

Connecting the tow bar is straightforward with the Twistlock system. The removable drawbars slide into the brackets, twist to lock in place, and that’s it—no pins or clips required. When you’re done towing, just twist them back to release and pull them out. It’s a quick, secure setup that makes connecting and disconnecting less hassle every time.

Strong Where It Counts: All-Steel Construction with Black Powder Coat Finish

The brackets are computer-cut from all-steel for precise fit and exceptional strength. The black powder coat finish holds up well against corrosion and road wear, keeping the hardware protected through plenty of miles. The setup bolts to the frame, so there’s no welding needed while still providing solid attachment points for your tow bar.

Built for Straightforward Installation: Bolt-On Fit with Included Hardware

The kit installs directly on the vehicle’s frame using the supplied instructions and hardware. There’s no welding required, and everything is designed for a custom fit to match your vehicle layout. Once mounted, you can hook it up with Roadmaster Quick Disconnects or any Roadmaster tow bar for an integrated flat towing setup that stays reliable trip after trip.

Roadmaster's EZ Twistlock series brackets are virtually invisible, easy to mount and simple to remove. Brackets install on your vehicle's frame to provide attachment points for your tow bar.

by:

Very good product at a great price. Instructions and video are for a 2013 terrain and things were a bit different on my 2015. When all screws and clips are removed the front piece cannot be just pulled forward. There is a rear facing clip and you have to pull to the side to remove from this piece. (pics attached)There was no PS cooler attached in front on mine. Remove washer bottle totally which consists of 2 nuts and 1 bolt otherwise you will never get back up plate for top brackets in. If you remove horns it also makes installing the top brackets much easier.



by:

Easy to install for the do it yourselfer. Good quality and fit. etrailer customer service was great too.



by:

Very well constructed. Fitting right side took some adjustment, I had to clearance the lower member hole in order to fit the bolt.
I installed the base plates myself, after the prospective mechanic claimed this was the incorrect fitment. Subsequent calls to Roadmaster produced a "No Fit" pronouncement, in spite of the lookup and even the printed instructions. Undaunted, I proceeded, and the fit was successful. YES, this DOES fit a 2007 Mini Cooper S Convertible.



by:

Installed on 2005 mini cooper convertible. Choose this base plate for our mini since it provided highest attachment height for tow bar (12 inches off ground, only requires 3 inch drop from back of RV), and attaches to mini frame more substantially that blue ox. Installation directions are nearly perfect, we had to widen holes on passenger side to line up with frame. Modification was approved by Roadmaster.



by:

The installation on this was surprisingly quick on my 2011 Fit (base/non-sport version). Everything fit well (no pun intended).

A few minor changes over the video as my car was slightly different:
- I didn't have to trim anything on the air dam -- the tubes lined up perfectly with the slots on my grill.
- There was a in the wheel on each side where the plastic bumper meets the steel body panel. I didn't realize they were there (they're hidden somewhat) so I ended up cracking the hole this screw was in, but everything came back together nice and tight anyway.



by:

It does what it's supposed to do, which actually seems to be special these days. In all seriousness we purchased this for out Liberty, which blew it's ending the first time we tried to go on a big trip. We had it taken off of that Liberty and put on another and that's what it was on for our tip from AZ to Chicago. We have connected and disconnected probably a dozen times and took the arms off to drive around Chicago. It works just like it should and it is nice to not have to worry about at least one item. Hightly recommend this system.



by:

Even I had to wait almost 2 months, I'm so grateful that I got the Roadmaster base plates and tow bar..:) It is so easy to be mounted and to operate with it... Thank you for the good product.... P.S You don't need to cut anything from the bumper plastic facial...so you can just skip that part from the instructions!



by:

The Roadmaster base Plate kit does what it was designed to do. A difficult install as the Smart ForTwo did not lend itself to an easy base plate engineering design.
Installed it myself though with help from the instructions and etrailer on line instructions. I like the finished base plate. It is barely visible protruding only slightly from the black lower radiator grill (see photo)



by:

Very happy with this product. Installation was pretty easy. I see no reason to pay someone to install this. True you have to take the bumper off and a large metal support beam but it was pretty easy. You just have to take it slow and not get frustrated. The bumper on the Honda Fit is held on with a gazillion little plastic clips and snap joints. Everything fits tight on a Honda so you have to be patient. My only complaint is they don't give you the exact torque settings. I had to consult a shop manual to get the correct torque values. They give a table at the end of the instructions that gives common torque values for various bolt sizes. I thought that was lame they could have given the correct value from the shop manual. Certainly not enough to lower my rating. This bar is awesome and when the drawbars are removed the base plate is almost completely hidden. My wife wanted nothing to show on the front of the car. She was very pleased with it.

In the picture attached the bar is almost completely hidden. All you see are two small black circles. It takes about 2 seconds to mount the drawbars, just twist and go. VERY sturdy. I tow my Honda behind the motorhome with confidence.

I had my tow car blow its engine in South Dakota while on vacation. It needed to be replaced. I bought a used car and ordered a tow bracket for it and had it shipped to one of my destinations so I could install it there.
Unfortunately that car also broke down but I was able to return it. I asked to return that bracket and etrailer accepted it back.

I found a different car and ordered the bracket for it plus a wiring kit. etrailer shipped those and they were there when I got there.

They were easy to install and fit exceptionally well. After having my wife drive the new tow car for 1000 miles we were happy to get back in the motor home while we traveled.



by:

Parts came very quickly. The base plates are really well make and of heavy material. If you watch the video it is a breeze to install. Make sure you have some new clips for your bumper as the old ones will break, not all but some. I ordered clips from Amazon. I used a vibrating saw with cutting blade and it did nice job cutting plastic bumper cover.



by:

very well made and just getting pickup ready for flat towing. Fast shipping and excellent service. Highly recommend.



by:

I received the base plate for my Miata at 4:30 Monday by 7:00 it was installed and ready to go.A great product fit very nicely.Ordering and follow up went great can’t wait to try it out Just need to decide on the tow bar we will use.The Falcon or Sterling .Thank you for a great product and service.



by:

It was a very easy install and it did great. Only got to use it for 2 months though before a semi drug his trailer across the back on my toad and totaled the vehicle.



by:

Installed on 2014 GMC Acadia. Very sturdy and heavy duty base plate. I installed it myself. You will need a little automotive knowledge and more tools then the average do it yourself-er. It took about 6 hours, by myself. It looks more intimidating then it turned out to be. You can't see it when not in use which makes it nice for the wife, since it's her car.
Pictures show the tow bar adapter. Sorry, no pictures of adapter removed.



by:

Roadmaster base plate for 2010 GMC Terrain. Very detailed instructions, great videos. Product was as described, no holes to drill, just replace factory parts with Roadmaster parts. Everything went together very well. I used the instructions supplied along with the video on my laptop. Hardest part was popping the bumper shroud back on due to colder temperature. I have a fair bit of experience with rebuilding classic cars so have lots tools and reasonable mechanical ability.



by:

Purchased the towing adapter for my GMC Terrain a few week ago, received it on time & boxed not damaged. Watched the videos’ about three time on how to do it myself and started one evening and finished it the next morning about three hours with Beer Breaks, LoL. All the parts fix perfectly, had no problems with any of the parts, Product is real sturdy and if you don’t know where to look at the bumper you will not see the hide away receiver brackets. Very nice product, do it yourself and save
Up loading two photos if it will let me one is with hide away brackets installed and the other one you can see is my complete tow bar attached to the hide away brackets



by:

easy to follow instructions, took about 3 hours to install. paper template for holes in facia would be great .



by:

Seems like a very well-made sturdy product. Instructions were good however the holes did not quite lineup like they were supposed to so I had to do some mild to moderate modification. I like the way it looks without the towbar on the base plate. It’s fairly well hidden.



by:

The baseplate fit perfectly and the video was very helpful



by:

Installed without a hitch! Matches up perfectly with the Roadmaster Stowmaster towbar we already had. Beautiful!



by:

Many reviews for this base plate said they could not hook up the U bolts. I had no problem using the U bolts. I did not tighten any bolts until I had them all in place. Then, I tightened all the nuts and bolts. I marked them with paint so I could see if any of them backed off. After a year, all of them are still tight. We towed our mini 4,000 miles in the first year.



by:

I rated it a five star because what I purchased was what you described it as and at the price you stated, parts I needed to tow car. Can not ask for more than that.



by:

These work great on my suzuki sx4.

  • Parts Needed to Flat Tow a 2011 Suzuki SX4 with a Blue Ox Aventa Tow Bar
    I would be glad to help you with your towing situation and what would be the best setup you can use. It will require more parts than just the base plates for your vehicle. If you can flat tow your vehicle, you will need to purchase base plates, wiring for lights, and a supplemental braking system as required by law. First, I would recommend to check your owners manual or with the Suzuki dealer to see if your 2011 Suzuki SX4 can be flat towed. I have information that says the 2011 Suzuki...

  • Mounting Points and Removal of Bumper Cover To Install Roadmaster Base Plates on 2012 Suzuki SX4
    The Roadmaster # 521019-1 Base Plate Kit for your 2012 Suzuki SX4 is indeed secured to the front side of the frame rails. Just like most of the Roadmaster Base Plates, the front bumper cover will need to be removed from the vehicle in order to access the front of the frame members so the base plate mounting brackets can be installed. Before attempting to flat tow the vehicle, I would urge you to consult the owners manual and Suzuki regarding procedures for safely flat towing the vehicle....
