To remove, simply twist the arms back and pull them out. 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.

2019 Chevrolet Equinox

The Jeep project went very well everything fit great and worked well. I really love Roadmaster products and quality and your company is the best place to purchase them. I sold the Jeep and replaced it with a new 2019 Chevy Equinox 2.0 L AWD and just purchased and installed the following items from you and installed them, RM-156-25 & RM-156-75 Battery Charge Line Kit, RM-146-7 Flex Coil Kit, RM-523193-4 EZ4 Plate Kit, RM-88333 Custom Seat Adapter, RM-751489 Stop Light Switch Kit and a RM-98160 Second Vehicle Brake Kit w/brakeaway. All these parts were in stock and arrived quickly and normal with you people, I really enjoy the o-line vidios as I do all my own installs. Thank you so much for your great service.
I will attach pictures of my install, you will see how I was able to fab a bracket and attach it to the existing mount on the base plate to mount the brakeaway switch and the air connection for the brake system.
I also fabricated a tail light bar as I didn't want to use mag-lights or splice into the factory lights and bulbs installed into the lights would not work as the factory brake lights will come on when the brake system is applyed and the turn siginals would not be visable.
Thanks for all you do, I would and do recommend you people to everyone who needs your products. Rob

Everything is working great, I installed a base plate kit, battery charging kit, stop light switch kit, second vehicle air brake kit w brakeaway and seat adapter on our 2019 Chevy Equinox and towed it about 14000 miles behind our motor home this past year and everything worked perfect not a problem with any product. These are great products, everything fit perfectly and performed perfectly. Thank you for great service and great products. Rob

2004 Jeep Wrangler

I am not quick to review a product, it's been over a year since I purchased and install this hitch.
After using this for a year, I found this to be excellent.
Absolutely no problems.
My wife and I installed it with no problems at all,,, easy to do.
The videos was detailed, letting feel comfortable in doing the job.

Sadly, selling the vehicle,, now we don't have it any longer.
However,,,
With our new vehicle, I am again going to purchase from this same company.
This fit our 2004 Jeep Wrangler X

2001 Jeep Wrangler

well I finally put my tow bar base plate on. I'm 82 years old so I had my doubts as to weather I could do this so I checked out a location that could have one this job for me but they wanted a hundred and fifteen dollars an hour labor so I said to hell with that . I looked at the directions that you sent with the Base Plate and said to myself, I can do this. Well I did it. Your instructions were dead on and I had no problem at all, In fact I hade a little fun doing it. Thanks a lot It's going to be great.

The base plate was as described, very good quality product. Install was easy, instructions were easy to follow. I had to call during install to clear up a question, they did not have the answer but called roadmaster while I waited on the phone and got me an answer. Very pleased with product, service and follow through.



by:

I received expert advice on the selection of the base plate needed for my Jeep Wrangler. The product came in a timely fashion and was in great shape when I opened the box. The instructions that came with it gave step by step instructions and great pictures. I cannot think of anything that I was disappointed with.

    We have the Roadmaster base plate kit part # RM-521424-4 which is a confirmed fit for your 2006 Jeep Wrangler and will work great with the Roadmaster Falcon tow bar you have now # RM-525. Then for a lighting kit the Roadmaster part # RM-152-98146-7 would be a really great solution that uses diodes to activate the taillights of the Wrangler.

  • Tow Bar and Accessories for Flat Towing a 2004 Jeep Wrangler Behind Motorhome
    You can use a tow bar like the Tow Ready # 63180 to tow your 2004 Wrangler, but keep in mind, the tow bar is NOT rated for speeds above 45 mph, so I'd recommend a different setup. In order to run at highway speeds, I recommend using a tow bar like the Roadmaster Falcon 2 Tow Bar, part # RM-520 and base plate kit # RM-521424-4 which is compatible with OEM double tube bumpers. You will also need a set of safety cables like # RM-643. The Wrangler will also need to be wired for towing. There...

  • Can a 2005 Jeep Wrangler TJ be Flat Towed Using a Roadmaster Stowmaster Tow Bar
    The Roadmaster Stowmaster, part # RM-501, has a maximum weight capacity of 6,000 pounds. From my research your 2005 Jeep Wrangler weighs, at the most, just under 4,000 pounds. So you should have no problem towing your Jeep. The base plate kit we carry for an 05 TJ that fits with the Stowmaster is the EZ4 # RM-521424-4. This will work on your Jeep as long as you have a standard front bumper and don't have front leaf springs. I've attached the install details. To wire the Jeep's lights...

If you also need a compatible tow bar you can use the Roadmaster Falcon 2 # RM-520. Other parts you may need to flat tow your TJ are safety cables, wiring for the lights, a supplemental braking system, and a high-low adapter. To power the Jeep's lights the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 includes the diodes, wiring, and connectors...

The tow bar I recommend is the Blue Ox Alpha, part # BX7365, which comes with safety cables. In order to be able...

  • Fit And Compatibility Of Base Plates For Jeep Wrangler U-Channel Bumper On 2003 And 2005 Models
    As models change, their towing ratings often change or the specific area of the frame is redesigned, either of which could be the case for your father-in-laws 2003 TJ Wrangler. Roadmaster determined that the mounting location of the Roadmaster XL Base Plate Kit - Removable Arms # 1420-1 wasn't sufficient so they replaced it with the Roadmaster EZ4 Base Plate Kit - Removable Arms # RM-521424-4. Even though it may "work" it is not intended to and is not recommended. The # RM-521424-4...

  • Can a Jeep Wrangler be Flat Towed by the Front Bumper
    I have a solution for you, however, I would not recommend mounting a tow bar directly to a bumper on a Jeep, whether it is OEM or an aftermarket bumper. Jeep does not recommend towing the Wrangler with the OEM bumper because it was not designed to pull the weight of the vehicle. Also, mounting a tow bar to a bumper would require drilling. I spoke with my contact at Pavement Ends and she said drilling into this bumper would void the warranty and they do not recommend using it to tow the...

  • Blue Ox Base Plate Kit that Fits 2005 Jeep Wrangler
    Blue Ox makes a base plate kit that fits your 2005 Jeep Wrangler with a standard bumper with the part # BX1120 which will work great with your Blue Ox tow bar. For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow vehicle to control the taillight assemblies of the towed vehicle. This comes with a round 6-way connector that you will install on the front of your towed...

    Neither the 1559-1 nor the 1419-7 base plate kits will work for your 1997 Jeep Wrangler, I'm sorry to say. We do offer kits that will work, though. I'd recommend the # RM-521424-4 base plate kit, which fits the standard or double-tube bumper, unless you have front leaf springs. If your Wrangler does have front leaf springs, let me know and we can look into another solution.
