Roadmaster Base Plates - 4427-1A

  • Removable Drawbars
  • Roadmaster
  • Hitch Pin Attachment

The crossbar-style hidden brackets attach to your vehicle's frame to provide attachment points for your tow bar. The visible portions of the brackets can be removed when you are not towing.


Features:

  • Hidden bracket design - drawbars are easily removable via 2 pins
    • Improved aesthetics compared with standard brackets
  • Computer-cut, all-steel construction provides exceptional strength
  • Black powder coat finish is durable and corrosion resistant
  • Simple installation - no welding required
    • Custom base plates ensure a perfect fit for your vehicle
  • Compatible with Roadmaster tow bars with use of quick-disconnect crossbar (910021-00 - sold separately)
  • Instructions and mounting hardware included

The square drawbars, or front arms, on the crossbar-style base plate kit are simple to mount and remove, easily securing with hitch 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.

2015 Ford Explorer

I am very happy with my resent purchase of the Roadmaster Falcon 2 Tow Bar and the Roadmaster XL Base Plate. It took me about 3 hours to install the base plate. The directions that came with the product and the instructional video on etrailer.com were a big help. The Falcon 2 Tow bar is easy to setup and use right away. I will be towing a 2015 Ford Explorer behind my RV. I have not used the setup with my RV, but I did tow the Explorer around the block a few times with my F150, just to see how it all hooked up. It was incredibly easy. Way better than dealing with a tow dolly, like I have for the past two years.

It fit my Explorer perfect and works great when I tow it behind my motorhome.

2013 Ford Explorer

Nice piece of metal work. Fit very well with a little hammer work. All the needed parts were provided. Very good Kit.



by:

works well



by:

Easy install, managed to put it on the same day I received it



by:

etrailer service is and has always been stellar. My order was correct and was delivered very quickly. The only reason I made this a four instead of a five was that the rear bolt position of both base plate brackets where welded on crooked. Each small plate was at a different angle from each other. In my opinion whoever welded them wasn’t paying attention to quality control. Because I was on a time crunch for my departure on a trip and could not wait for replacements (and I needed the vehicle for local driving) I made the brackets work. Other than that the installation went smoothly and I was able to test tow my 2004 CRV a couple of times without incident.



by:

Very impressed that they're the exact fabbed fit, and easy to install! These tow base plates are super sturdy!



by:

Item arrived earlier than predicted after viewing a very complete tracking system. The information was very clear and precise. Good job! I am 75 years of age and installed the baseplate myself. Only a couple of minor issues. One pin would not insert. Welding blob in the way. Filed it smooth and problem solved. The video was excellent but was a bit different in that it showed a different method o rear bolt installation, however the instructions on paper showed the correct way. Reinstalling the front clip had presented some difficulty. I suggest really watching the inner fender position relative to the front clip before removal. All said all went well. The finished look is great, (see pictures). Great product!



by:

Just completed a 6600 mile rod trip, towing the Subaru behind a motor home.

Worked great.



by:

I've towed with it many times and Zero problems. I did find that moving the car slightly forward after stopping helps relax tension amd.make.disconnect much easier. Overall... I'd say SUPER..!!

Base plate 1910 install on 1999 Landrover disco 2

the base plate arrived fast (as does everything I have ordered from etrailer). It was a bit bent on arrival but Becky sorted me out and offered to replace it but it was easy to bend back (with a 3lb hammer).

The included instructions were great for removing the bumper but nor much else. Possibly because my Landy is a 1999 disco 2 and the pictures were of a 2002.

I have included some pictures of stuff I wish I had known. Firstly I had to loose the recovery loop on the driver side as the base plate would not fit over it. The chassis frame has steel tubes inside the bolt holes so the amount of drilling is minimal (I ordered a drill bit that they suggested but in all honesty could have opened up the holes with a file easily).

You need to oval out the aluminum crush cans before you replce them or the new bolts will not go through. The center mount bolt just needs the plastic mount for the center screw on the scoop cut out and there is a bog square hole on the top of the member (thats why you need to big square piece of steel on the top of the center bolt)

Mine was obscured by the torsion bar so I ended up dropping it to drill out the hole and get the bolt in straight.

It was easy to bolt up to the frame once everything was prepped and do yourself a favour and buy loctite red for the bolts - you don't want to be going in there again.

The bumper template was a good start but I had to reshape mine a lot particularly as the hole on the baseplate ended up halfway through the bumper and I had to do a lot of enlargement at the bottom to attach the safety wires.

The photos should make more sense of some of my description



by:

It was easy to install, fit well and came with good instructions.



by:

Everything looks good for us, but we have one more part that we are waiting on before we can install on the truck plus it's raining out here in Washington State. when it's time to put it all together we will take a picture and send it.



by:

The baseplate and crossbar arrived one day earlier than expected. Directions were included which made the installation pretty easy.
I am happy with etrailers products and will buy from them again.



by:

Very easy to install and works great



by:

This base plate was installed on a 2008 Kia Spectra. The bracket is strong and not really hard to work with HOWEVER,,,,,,,,,, I am used to the BlueOx base plate which is much easier to "hook up". Unfortunately, BlueOx did not make a base plate to fit my vehicle. That is not a big problem as I'm usually not in any hurry and it only takes maybe 5 minutes longer to "hook up".

The biggest problem with the RoadMaster base plate is that due to the way it is bolted to the frame, it only allows for a 6-inch ground clearance on the front of the vehicle. I have to be very careful with any "dips" in the road, especially on cross streets. Six inches may not sound like much but since the tires are several feet behind the base plate, it reduces that ground clearance greatly. It also will not clear the concrete "stop blocks" in front of many parking spaces.

If you are not very careful and keep this in mind, you may likely bend the frame of your car when you come to one of these sudden impacts. I haven't bent anything yet but it has certainly been shocking when it hits. Most of the time, the impact will cause the base plate to scrape and lift the car to the height to clear the obstacle.

I've attached a picture with a ruler in the view.



by:

Good information and prompt shipping.
Base
plate is solid and install and use instructions are excellent.
Be warned that product install is drill two holes and install 3 bolts, BUT the entire front panel has to be removed and replaced. Not difficult, but time-consuming.
Seat bracket is solid and install and use instructions are excellent.
Brakemaster kit is good quality, but instructions are not as good as most Roadmaster products. Instructions for air line install are especially weak.



by:

The hardest part of the installation is getting the grill off and back on. Of the six preexisting holes all but one lined up the sixth hole was off about a half inch but the car had hit a deer a few years ago.



by:

My husband and I were able to install the Roadmaster base plates on our 92 Jeep Cherokee in just a couple of hours. It went on pretty much the same as the demonstration video on the etrailer web site. The minor differences were addressed in the printed instructions that were included in our package. We haven't put it to the test yet as we still need to tackle wiring for the Roadmaster Even brake system that we purchased second hand. We will be towing our Jeep with our 93 Safari Trek. Customer service provided by Marty was excellent. I will provide pictures at a later date.



by:

Installed on a 2010 Ford Ranger Sport 2wd
Have
towed over 10000 and not one issue. I did the install without one issue, picture perfect, I did use a online video to get a general idea of install otherwise I primarily used manufacturer's. . Be sure to use the recommended/ required locktite product.
Enjoy!!!



by:

Base plate kit was fairly easy to install,all hardware was included and directions were clear! I would definitely buy another to install if ever needed. I do have a car lift making it easier,but would not be bad without,just a little harder on the knees!



by: 11/02/2023

This was a very simple install. This is my 4th baseplate I have bought and 2 pintle tow bars. Always excellent craftsmanship



by:

Great product, shipping was FAST. Instructions were adequate, but minimum - this was not surprising, you have to know how to bend wrenches to install something like this yourself.
I had a factory-installed tow hook on each side that had to be uninstalled, but once you remove the front bumper shroud it is easy to remove and all the bolts are easy to remove. Once the hook was out of the way, easy-peasy!



by:

Great product and easy to use . Car tows great behind the motor home.



by:

Super nice people at etrailer. I wasn’t sure exactly what I needed and they helped me pick out the best hitch for me.

  • Recommended Flat Towing Set Up for a 2014 Ford Explorer
    To flat tow your 2014 Ford Explorer Police Interceptor model you are going to need a base plate kit, a compatible tow bar, with safety cables, a wiring harness, a supplemental braking system, and a charge line kit. It looks like your Entegra Vision XL 36C motorhome has standard brakes. I have recommended compatible parts. We'll start with the baseplate kit because you specifically asked about it.

Both base plates are also compatible with your Roadmaster Falcon 2 Tow Bar # RM-520. If you don't already have safety cables, cables like # RM-643 are required when flat towing. Other components needed to flat tow are a wiring harness for the towed vehicle, like # 154-792-118158, and a supplemental braking system, like...

  • Recommended Roadmaster Base Plates And Adapter To Use Blue Ox Aventa Tow Bar On 2014 Ford Explorer
    In order to use a Blue Ox tow bar with a Roadmaster base plate on your 2014 Explorer, you will first need the Roadmaster XL Base Plate Kit, part # 4427-1A. The # 4427-3A will not work with the Aventa tow bar. The tow bar adapter you will then need is part # RM-033. This adapter mounts to the plates on the 4427-1A base plate kit and your Aventa,, part # BX7450 or part # BX7445. For a cost savings, you may want to consider the Blue Ox Base Plate Kit, part # BX2632. This would require no...

    According to Roadmaster, the XL Base Plate Kit, # 4427-1A, will fit on your 2013 Ford Explorer Sport with the twin turbo eco-boost engine. If you are planning to flat tow your Ford Explorer, I would first recommend checking your owners manual for any restrictions or limitations on flat towing your vehicle.

    The first thing you will want to do is check the owner's manual for your vehicle. Sounds like you either need to disconnect the battery or pull a fuse(s).

To use a Blue Ox Alpha tow bar with the Roadmaster # 4427-1A, you will need an adapter, part # RM-032. To wire your Explorer for flat towing, you would need wiring kit # 154-792-118158. Most states now require a supplemental braking system that would activate the Explorer brakes in tandem with the motorhome. You can see the available choices by...

  • Do Base Plate Kit Installs Ever Deploy Air Bags in Vehicles

    I did some checking and the 4WD versions of the 2015 Ford Explorer can be flat towed. There are a few recommended procedures you will need to follow in the owners manual though. The easiest braking system to set up and use is the Blue Ox Patriot # BLU37TR, that applies the vehicle brakes in proportion to how much the tow vehicle is braking.
