Features to know about

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

When you’re not towing, you don’t want a bulky bracket sticking out from the grille. The EZ Base Plate Kit keeps things clean with a hidden bracket design that’s virtually invisible once the arms are removed. The drawbars twist out in seconds, leaving only the discreet brackets tucked within the grille—protected from scrapes and giving your front end a factory look.

Quick Hookup Every Time: Twist-Lock Attachment System

Connecting your tow bar shouldn’t be a fight. This kit uses Roadmaster’s Twistlock system so each arm simply inserts into the bracket, then locks into place with a quick twist—no pins or clips needed. When it’s time to disconnect, twist again and pull them free. It’s simple, solid, and makes hooking up on your own straightforward and fast.

Strength You Can Trust: All-Steel, Computer-Cut Construction

Flat towing puts serious load on your setup, and this base plate is built for it. Each bracket is computer-cut from all steel for precise fitment and consistent strength. A black powder coat finish resists corrosion and looks sharp for the long haul. With no welding required, you get solid, bolt-on strength ready to handle thousands of miles of towing.

DIY-Friendly Setup: Custom Fit with Included Hardware

Everything comes ready for installation—mounting hardware and instructions are included right in the box. The custom-fit design lines up with factory mounting points for a straightforward install using basic tools. You’ll just need fishwires (C58400, sold separately) to complete the job cleanly. It’s a project most DIYers can tackle over a weekend with confidence.

Compatible With Your Current Gear: Works With All Roadmaster Tow Bars

No need to worry about matching parts—this EZ Base Plate Kit is compatible with Quick Disconnects and all Roadmaster tow bars. That means you can keep the equipment you already trust while adding an easy-to-use, dependable connection point to your setup.

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.

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:

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:

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



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:

Thanks for being a great knowledgeable person about this tow set up. It fit perfect and the directions made it a no brainer



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:

Fast shipping Very goog instructions 5 hours start to finish
Great fit

by:

I have used Roadmaster Base Plates for many years. They are a great product.



by:

Base plate was bent during shipping. Box was destroyed when I got it. Had to spend an extra hour trying to straighten it out before I could even start installing it. You may want to try a different shipping company. The bracket is of good quality as the last one I had installed.



by:

Perfect fit! This was installed on our 2010 Chevrolet Malibu tow car. My husband did all the work himself. He is 74 years old! We've only made two trips because of covid-19 but everything works just perfectly. There were a few little adjustments as you would expect with any job that big, but we are very happy with the setup. Thank you again so much.



by:

I appreciate the quick fulfillment of my order and prompt shipping. Excellent!



by:

I had Roadmaster base plate on the car traded in I wanted Roadmaster product again because I like it and trust it.
It was delivered sooner that I thought. Surprised to see that my order was processed the same day as ordered even though the order was placed near the end of the day. I always had good luck with "e trailer" It's not the first time I order from e trailer.

by:

The order was taken very professionally and handled with care and understanding. It was easy to follow the delivery and we were extremely pleased with the product and especially the service. It is nice to see that there is someone in the United States that still handles customers with respect and realizes there is no business if there are no customers. We would definitely use you again.



by:

Happy with price, ship time and quality of product. Directions and videos were excellent and very helpful in installation. Install time was 4 hours for 2 men with all the right tools and a hydraulic hoist to work off of - so plan ahead. This particular base plate on this particular car (both are black) looks really good - well hidden.

  • Parts Needed to Flat Tow a 2011 Chevy Malibu
    When flat towing a vehicle, there are 5 main components that are needed. Starting with base plates, for a 2011 Chevy Malibu you can use Roadmaster EZ base plates # 523145-5. The base plates provide a safe and secure attachment point for a tow bar. When choosing a tow bar, you will need one that is compatible with EZ base plates.

If your StowMaster tow bar does not have the vehicle side Quick Disconnects, then you will need those as well. I also recommend checking your owners manual...

    The SMI Stay-IN-Play DUO Supplemental Braking System, part # SM99251 is a vacuum-assisted supplemental braking system and will engage the brakes on your Malibu with the same intensity as the braking action of your towing vehicle. I have attached a link to an installation video of this system on a 2010 Malibu you can check out. I also recommend using a stop light switch like part # RM-751210-1. This wires into the Malibu fuse box and activates the brake-monitoring system whenever the brake...

  • Base Plates, Tow Bar, Safety Cables, Lighting, and Braking System to Flat Tow a 2009 Chevy Malibu
