Features to know about

Built Strong for Heavy-Duty Towing: All-Steel, Computer-Cut Construction

This kit is made for serious towing strength. The brackets mount directly to the frame and are cut from solid steel for an exact fit and even load distribution. The black powder coat finish adds durability and corrosion resistance, so it stays solid through long miles on the road. No welding is needed—just a straightforward bolt-on install using the included hardware.

Clean Look When You’re Not Towing: Hidden Bracket Design with Removable Arms

If you like your front end to look stock when you’re not hitched up, the removable drawbars make that happen. Each arm detaches easily by pulling two pins, leaving behind brackets that stay tucked inside the grille. Once the arms are off, the setup is nearly invisible and protected from scrapes or scuffs.

Faster Hookups Every Time: Direct-Connect Design, No Crossbar Required

This direct-connect setup skips the extra crossbar found on older systems, so getting ready to tow takes less time and keeps everything looking cleaner. The bracket design means each arm slides in securely with pins—simple, solid, and ready to go. It’s compatible with Roadmaster tow bars that plug directly into a trailer hitch receiver, such as the Nighthawk, Sterling, Blackhawk, Blackhawk 2, Falcon, and Falcon 2.

Confidence on Every Trip: Secure Safety Cable Mounts Built In

Safety cables connect right to the tabs built into the removable arms, giving you a reliable anchor point that keeps everything in place while towing. The design keeps cables organized and accessible so you can hook up fast and roll out with peace of mind every time.

Specs

Construction and Design

  • Design: Direct-connect brackets install onto your vehicle's frame to provide attachment points for a motor-home-mounted tow bar
  • Bracket Design: Hidden bracket design - drawbars are easily removable via 2 pins
  • Construction: Computer-cut, all-steel construction provides exceptional strength
  • Finish: Black powder coat finish is durable and corrosion resistant
  • Installation: Simple installation - no welding
  • Fitment: Custom base plates ensure a perfect fit for your vehicle
  • Crossbar Requirement: No crossbar needed - faster hookup and sleeker appearance
  • Compatibility: Compatible with all Roadmaster tow bars that slide into trailer hitch receivers
  • Included Components: Instructions and mounting hardware included
  • Country of Origin: Made in the USA
  • Warranty: Limited Lifetime Warranty

Note

  • Note: Direct-connect base plates will work only with the Roadmaster tow bars that slide into a trailer hitch, such as the Nighthawk, Sterling, Blackhawk, Blackhawk 2, Falcon, and Falcon 2. These base plates will not work with tow bars that require a hitch ball.
  • Direct-connect brackets do not require a crossbar because of the heavy-duty nature of your vehicle's frame. Thus, installation is simplified, the hookup process is faster, and the total appearance is enhanced.
  • Note: The EZ Hook safety cables included with Roadmaster's Sterling tow bars will not work with direct-connect base plates. These cables connect to an anchor plate on the Quick Disconnect crossbar, which will not be present when you are using these base plates.
  • The drawbars, or front arms, on the direct-connect base plate kit are simple to mount and remove, easily securing with pins. Once the drawbars have been removed, the remaining brackets are virtually invisible. On most automobiles, the brackets are mounted within the grille, where they remain not only unseen, but protected from scrapes and scuffs as well.

Installed the direct connect kit on our 2009 Subaru Forester to serve as a towable behind our motorhome. Once installed the kit blended well with the car and only minor modifications were required to the fascia. It was not really noticeable at all with the towing arms removed. The tolerance on the baseplate frame holes was slightly off. I had to drill mounting holes and route them out slightly to match the body mounting positions. Our Subaru did not have an body damage so I think the factory got the holes slightly off center. Note- this baseplate replaces the actual bumper on the Subaru so it leaves a gap between the baseplate and fascia that was not there with the factory bumper. Not a problem, just be prepared for that.

Installed on my 2013 Subaru Forester. Had to file down the passenger-side hole on the bottom (not the front where it replaces the old bumper) because the hole came at an incorrect distance from the factory compared to the driver's side hole.

I also installed the "RM-98146-7 Roadmaster Wiring - Straight 6 to 7 - 78" Long" which required a small semi-circle be cut off from my car's bumper facia next to the base plat's arms. It's not noticeable from the outside but otherwise the female plug wouldn't be able to open to accept the male plug.

Side note: If your car is used, do yourself a favor a purchase a bag of push clips (the things you'll need to pop off to get the facia off on your vehicle) from [online vendor]. Mine were stiff and more than half of them broke when I first popped them off.

Had these installed at Lester’s Automotive in Boerne,Texas…First class service all the way. Paul and his crew worked through lunch for over 4 hours to install these on our 2026 Ford Ranger. Also ran the wire and hooked up my auxiliary tow lights. The price for this was very reasonable and would highly recommend them for all r.v. needs even if not real close to the Boerne area. R.V park within reasonable distance if needed.

Etrailer comes through again! This was a great savings as a used kit, but it was even better than the description online. I have installed (4) baseplates on and etrailer.com has given me great videos to watch and good instructions to follow. Couldn't be more pleased with the quality, service and delivery times.

It mounted up just as the instructions said it would. From previous research I was not surprised when some of the mounting did not align perfectly. Had to use a dremel tool to make it work. The product looks very sturdy from its design. I’m happy with it and look forward to RV traveling.

Pathetic and just talking to Noah he states he will get to my issue later when he has time!! My car is on jacks all torn apart and I think Roadmaster gas misled advertising. This 523228-5 baseplate is NOT MADE FOR 2026 CHEVY TRAX!!!

Which trim is your 2026 Chevy Trax? Per Roadmaster, the # RM25EQ (523228-5) fits all trims of the 2026 Trax except the ACTIV trim....

The 523228-5 DOES NOT FIT MY 2026 CHEVY TRAX LT! Look at the side braces in your video of a Demco base plate install (upside down "U"). That is what is needed for my install. In Roadmasters install instructions, page 7, items #2, #3 have no frame in that area to bolt to & #5 has only one ho l e on bact end and putting a bolt in that hole leaves 3/4" short of main base plate. I sent pics to verify this to Noah on 9/22 @ 11:46AM. I know, unless you tried this install personally you are going by Roadmaster's word. BE CAREFUL IN SUGGESTING THIS FIT UNTIL YOU VERIFY. I just do not want someone else to have this experience. Thoughts ?

This works perfect with my Roadmaster tow bar. It was a little difficult to install since I had to remove the front end of the Trailblazer, but with the good directions that came with it and some you tube videos made the installation easier.

Customer service was very helpful. Easy to install. No bumper or grill cutting however, you do loose your front hooks. Nice low profile.

I bought and installed this tow plate one year ago on my 2013 Jeep Wrangler. I bought this particular plate due to the jeep having a Barricade off-road bumper. This plate attaches a bit lower than other plates and prevented having to modify the bumper. Installation was easy involving only hand tools. The plate comes with all needed bolts and attachments. I have towed this Jeep several thousand miles behind my RV with absolutely no issues. As an aside, I use a Roadmaster Night Hawk tow bar which is also an excellent product. Both are expensive, but I believe cheaping-out on safety is no a good idea. I highly recommend this product.

I just followed your video of the installation and it was on point !
by:
I have lots of issues with this tow bar. Initial installation was difficult due to a tight fit. Had to have my mechanic cut holes in frame to get bolts attached. After a few times of use the bolts failed causing the bar to fall fwd that then damaged my hitch arms. To fix I drilled new hole through bar and frame securing it with a #8 bolt. To reinforce it I used turnbuckles attached to my bumper. last tow finally went well.

It’s a super strong and wonderfully engineered addition to my new Maverick pickup.. Couldn’t be happier with it!!!!! Well done!!!!
by:
The product is great - I gave 4 vs 5 stars only because I had to drill the rear holes out as they did not align with the holes in my frame and I had to drill out the hole in the bracket to align with my frame extension hole, again bracket did not align with the existing hole. However, in general it appears to be a solid mount.
by:
Great Base plate, had to modify the non-oem bumper a little to get the clearance needed to get mounting holes lined up. Once that was done, everything went pretty quickly finished and tested. Towed 600 miles and worked flawlessly. Much better than using the bumper tow points, as they were elevated causing a very bouncy towed on bridge aprons. Bumper tow points also let the towed have minor side to side movement, this does not, so a lot better towing experience.

The Roadmaster Direct-Connect Base Plate Kit has performed flawlessly over the past year. With almost 10k miles logged during our 3 month trip across the US, the components have remained as installed and operated as expected.

I really like the way it is hidden and doesn't stick out like a sore thumb. My Rubicon X has a metal skid under the bumper that I cut holes in for the base plate tabs to protrude. I made 5 or 6 trips to my shop to get it right. Would be nice if it came with a paper template showing where to trim. It bolted up perfectly and seems well made.

2018 Mazda Miata
I installed this base plate on a 2018 Miata RF. I think I recall something about it taking 3.5 hours and my initial estimate was 3.5 days. It actually took a bit longer than that, but I was not pushing myself and did not have the luxury of having the vehicle on a lift but had it up on two ramps for the front wheels.

The order came pretty quickly, probably about 4 or 5 days between the time I placed it and UPS delivered it. The parts were well packaged and it came with a printed set of instructions. I had watched the video install on another Miata and if it weren't for that I'm not sure I would have tried it. I'm not a pro mechanic by any means but have worked on my own vehicles now for over 40 years. And I'm not a spring chicken either, so all the up and down working on the car can tire me fairly quickly. But if you are not in a rush and go carefully it can be done.

It took a day to do most of the disassembly. I removed both headlights and the intake tube on the passenger side. That tube came out much easier then it went back in.

The next day I got the baseplate mounted which helped to start visualizing how it all would work. All of the holes for the 6mm bolts did not quite line up with the holes in the frame. I had to file one sides worth for a bit of extra clearance. From my experience on this install you really want to leave all the bolt on the loose side till you get everything situated.

A couple of days off for rain and the then I got to work on the bracing. Initially I though I didnt need to cut the top lip of the frame but I decided to go ahead and do it anyway since that part didnt seem to sit flat when bolted from the back end. I'm still not sure its really necessary as the hump clears the metal lip without cutting it.

I also ordered a 14" long 1/2" drill bit to cut the holes in the frame. It was a Bosch bit, wasnt very expensive and it went through the metal like the proverbial hot knife. I managed to get all the big bolts installed in a day with a great sense of satisfaction.

The next day I torqued down all the bolts and the mount felt very solid. They stress that you need to install all the bolts, but honestly I can't see the 6mm bolts doing much compared to the half inch bolts that do most or all of the work. But I put them in and tightened them all the same.

A couple of days spent to install the tail light wiring and then I got back on to putting the front clip back on. My car must have had an aftermarket grill since it did not match the pictures or the video. I tried to position it carefully to see where the parts that were going to stick out would be so I didnt cut out more than I needed to. So there was a good amount of back and forth, cut and fit. In the end I had to make some extra cuts for clearance for the safety cable tabs as well as the mount for the 6 wire connector. Until I made the extra cuts the lower part of the front clip would not seat correctly. Getting the clip in the right position so it fits under the lights also takes some finagling.

Figuring out where all the bolts go back in can be interesting. Take pictures where you can. Dont be too aggressive when working with plastic parts. Overall I'm satisfied with the install, but I have yet to try and hook it up to tow.

  • Where do Safety Cables Attach to Base Plate 921-3 on 2009 Subaru Forester
    Tow bar safety cables are generally connected between the safety chain loops built into the flat towing base plates on the towed vehicle and on the other end to the safety chain loops built into the hitch on the towing vehicle. The instructions for the Roadmaster MX base plate kit # 921-3, which are linked for you, show the safety chain tabs built in to the removable arms. I took a diagram from those instructions and on it I indicated the locations of the tabs that are on the outside edges...

  • Is Base Plate Kit All that is Needed to Connect to Tow Bar
    To connect to a Roadmaster tow bar all you need is a base plate kit and your set. For that the Roadmaster MX part # 921-3 would be all you need in that regard. A very popular tow bar to use with this base plate is the Roadmaster Falcon part # RM-520.

  • Which Roadmaster Tow Defender Fits with Roadmaster MX Direct Connect Base Plates
    I do have a solution for you and you are correct that the Roadmaster Tow Defender # RM-4700 is not compatible with the Roadmaster # 921-3 base plates, since those are direct-connect base plates in the MX series. The series/model of the base plate is listed at the bottom of the product page with the Roadmaster part number, but it is a bit difficult to find if you're not specifically aware it's there-so we do apologize for the confusion. With that said, you can use the Roadmaster Tow Defender...

  • Recommended Lower Cost Flat Towing Components for 2009 Subaru Forester

The 2009 Subaru Forester has a weight of 3,250 to 3,440 lbs so the towing capacity and the weight of the Forester will determine if you can safely use it to tow it with your Ascent.
