Features to know about

Built for a Clean Front End: Hidden Brackets with Removable Arms

When you’re not towing, you still want your vehicle to look good. This kit’s hidden bracket design keeps things clean by mounting within the grille area, leaving the front end virtually invisible once the arms are removed. The drawbars twist and pull out easily, so there’s nothing hanging off the bumper when you’re not on the road. It’s a slick, low-profile setup that protects the brackets from scrapes while keeping your vehicle’s original look intact.

Quick Hookups Every Time: EZ Twistlock Connection

Getting ready to tow doesn’t have to be a hassle. The EZ Twistlock arms slide into place, twist to lock, and you’re set—no pins or clips to fumble with. When you’re done, just twist them back and pull them out. The smooth-fitting design makes it simple to connect or disconnect even if you’re working solo, and it lines right up with your Roadmaster tow bar setup for a solid, secure connection every time.

Strong Where It Counts: All-Steel, Computer-Cut Build

A solid tow starts with solid metal. These brackets are computer-cut from all-steel for precise fitment and exceptional strength. They bolt directly to the frame with no welding needed, spreading towing forces evenly across the chassis. The black powder coat finish holds up against corrosion and daily wear so you can trust it through years of use and miles on the road.

Ready for the Long Haul: Compatible and Complete Hardware

This kit is made to integrate cleanly with all Roadmaster tow bars and Quick Disconnects, so matching it with your existing gear is straightforward. Instructions and mounting hardware come in the box, making setup easier from the start. For a complete installation, fishwires (C58400 – sold separately) are required to finish the job right. Once installed, it’s a dependable base plate setup for reliable flat towing wherever you’re headed.

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 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.



by:

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:

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.

Ease install, Great Quality



by:

Great service. Outstanding delivery time. Very helpful customer service.



by:

A little more cutting on the plastic pieces under the car than I expected but not too difficult. The customer service was excellent. There was going to be a delay on the ship date. I however had to have the hitch for my job and could not wait. They jumped through whatever hoops they had to and got it to me the next day. Thank you etrailer.com in a world where customer service seems to be disappearing you really excelled

  • Parts Needed to Flat Tow 2007 Saturn Aura
    According to the owner's manual, a 2007 Saturn Aura can be flat towed so long as the vehicle is facing forward and it is run for five minutes before being towed and during each RV fuel stop. You'll also need to pull fuse "IGN SENSOR" to prevent the Saturn's battery from draining. There are a number of parts you'll need in order to flat tow your Aura, starting with base plates. The Roadmaster EZ # 523145-1 are a confirmed fit, and I recommend using the Roadmaster Falcon 2 tow bar # RM-520...

  • Parts Needed to Flat Tow 2007 Saturn Aura XR
    I was able to determine that your 2007 Saturn Aura XR is flat towable as long as you follow the outlined instructions in the owners manual. First thing you'll need is a base plate kit. For that you'd want the part # 523145-1. In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle. The most popular compatible tow bar is the Falcon 2, # RM-520. For safety cables you can use # RM-643. The coiled design...

  • Parts Needed to Flat Tow a 2009 Saturn Aura
    If you are under the 3,500 lb capacity of the hitch you have on your 2002 Fleedwood Tioga, even just by a little bit, you should be fine. You will want to verify the weight of your vehicle though at a weigh station just be sure that the advertised curb weight is accurate. Also, you will need to make sure you don't ever load any cargo in the vehicle when you are flat towing it as that would put it over the 3,500 lb mark. For a base plate kit for your 2009 Saturn Aura you would want the...

  • Is Roadmaster Sterling Tow Bar Compatible with Demco Base Plate on 2008 Saturn Aura
    Your Roadmaster Sterling All Terrain, Non-Binding Tow Bar # RM-576 can be used with the Demco Demco Classic Base Plate Kit # DM9518206. You can ditch the crossbar but you will need the Adapter for Roadmaster Tow Bars to Demco Classic Base Plates # DM9523036. Because of the additional cost of the adapter, I would personally get the Roadmaster EZ Base Plate Kit # 523145-1 instead to save the extra money.
