Roadmaster Tow Bar Base Plate - 4427-1A

  • Roadmaster
  • Removable Draw Bars
  • 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
  • Made in the USA

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.



by:
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:

I was pulling my truck using the roadmaster crossbar and to my surpass the towbar broke in half as I was towing. Good thing I was in town only going 20 miles poer hr.



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:

Base Plate kit was complete and generally straight forward to install. Some instructions and dimensions were not explained in detail as they could have been. Especially the modifications made to the air dam were totally off. Most of the air dam is cut off to fit in front of the base plate. This was installed on a 2014 Chevy Captiva four cylinder car.



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:

Quick and easy install. Did not need to drill any holes.
Installed this base on a 2003 Chevrolet Tracker ZR-2.
Highly recommend this towing base.



by:

Item arrived very quickly. It appears to be of excellent quality. The salesman that helped me was very good and had very good knowledge of the product. The installation instructions were a bit vague, but I was able to figure them out. The price of the item was a bit higher than I was expecting.



by:

Highly recommend E-Trailer for all of your towing accessories. Great product, great customer service!!



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..!!



by:

Timely receipt and the installation was accomplished easily after watching the video.



by:

Looks great installed. I think it will work perfectly for towing my F150 4x4. Took approximately 1 hrs. I removed the bumper, 4 bolts, and installed effortlessly. Nice appearance!



by:

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

Worked 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:

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



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:

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:

Great value, great fit, very easy and simple installation. Although I wish there were 2 choices for size of receiver. I had to buy an adapter for 2” receiver and it protrudes farther than I’d like. Great company and free shipping



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:

Needed these for my 4Runner. Had to do a bit of grinding on the frame rails to get em to fit. I suspect just different year manufacturing tolerances. All in all, pretty easy to install if you are even semi mechanically inclined. Havent towed it yet but got all the bits and pieces and to fit together just like it should. Easy to remove and good clearance underneath

    We do have a base plate kit that fits the 2014 Ford Explorer and would allow you to use your Blue Ox BX4322 Rangefinder tow bar.

  • Does Installation of Blue Ox Base Plate Kit on a 2014 Ford Explorer Require the Bumper to be Removed
    The Blue Ox base plate kit, part # BX2632, does require the bumper to be removed from a 2014 Ford Explorer. If you're looking for a kit that doesn't remove the bumper we have two from Roadmaster, the XL kit part # 4427-1A and the MX kit part # 4427-3A, that keep the bumper. They fit the 2014 Explorer as long as you don't have the 2.0L EcoBoost engine. If you need to connect the base plate kit to a Blue Ox tow bar we carry adapters for that. Use part # BX88178 with the XL kit or part...

    The main difference between the Roadmaster MX Base Plate Kit part # 4427-3A and the Roadmaster XL Base Plate Kit part # 4427-1A for your 2014 Ford Explorer has to do with their compatibility of tow bars. The XL Base Plate Kit is compatible with all Roadmaster tow bars whereas the MX Base Plate Kit is only compatible with Roadmaster tow bars that slide into trailer hitch receivers. The XL Base Plate Kit will also require a crossbar and the MX Base Plate Kit will not. If you are using the...

    All you need is the correct adapter to connect a Roadmaster Falcon 2 Tow Bar part # RM-525 to a Blue Ox base plate kit. For that you would need the part # RM-031. This will replace the ends of the tow bar arms with ones that will adapt to the lugs of the base plate.

  • 2015 Ford Explorer 4x4 Flat Towing Parts Recommendations
    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. This is the safest way to stop and it reduces wear and tear on both vehicles. For a base plate kit you would want the # 4427-1A that you referenced....
