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.

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

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.

Perfect fit for my 2002 Jeep Wrangler. Makes hooking up to tow easy. There was some drilling that had to be done to the Jeep frame, but I already knew that before purchase. Etrailer was great and I will purchase here again.

I would definitely use and recommend y'all again.

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.

Review from a similar EZ4 Base Plate in Base Plates


Had Base Plate installed today, shop gave me 2.5 hr labor time. I returned just under 2hrs and they were backing my car out the shop. They parked it facing me. I told the Mechanic "That was quick" He said that's because it wouldn't fit. I was disappointed and asked what do I owe you for your labor> He laughed out loud and said it on there, but hard to see. I was so surprised and pleased you have to just about get down on your knees and bend down to see it. took me about 8 min to install everything and connect it to the Tow vehicle. I'm very pleased with it.

Review from a similar EZ4 Base Plate in Base Plates


This tow bracket base was a little tough for an old senior but very straight forward install. Everything went as the instructions said. The product is very well built and looks good where it comes through the front bumper cover. As usual the customer service and fast shipping from etrailer is exceptional.
I have had many purchases here and it's always great. I give etrailer itself 5 stars as well as the products.

Review from a similar EZ4 Base Plate in Base Plates


This was my 4th install for a dingy (with 4 wheel flat towing) in the last 20 years. This install is for a 2018 Jeep Grand Cherokee, Overland. The New ROADmaster 90* twist & lock removable base plates are REALY Awesome! So much much easier & faster than installing & removing locking pins! One picture shows a Brush guard from ROADmaster no longer available.

  • Preparation Procedure for Flat Towing 2009 Jeep Wrangler with Manual Transmission
    When the transfer case of your 2009 Jeep Wrangler with manual transmission is placed into the Neutral the driveshaft will be disengaged from the powertrain. This will allow the vehicle to move with all wheels down despite the transmission position. The owner's manual does not specify which gear to use, as you noted, but most owner's put the Jeep's manual transmission into 2nd or 3rd gear based on what I read online. You might contact a local Jeep dealer with your Wrangler's VIN which...

  • What Gear Should The Transmission Of A 2005 Jeep Wrangler Be Placed While Flat Towing
    There isn't a specific gear listed by Jeep to place your 2005 Jeep Wrangler Sport manual transmission in while flat towing it. Most Jeep owners prefer either 2nd or 3rd gear so it's really just up to your personal preference. The point of this is to keep the transmission components lubed while flat towing your vehicle.

  • Recommended Components Needed To Flat Tow a 2006 Jeep Wrangler
    For your 2006 Jeep Wrangler, I recommend the Roadmaster EZ5 Base Plate Kit, # RM-521424-5. This base plate kit has hidden mounting brackets and removable drawbars to give your Jeep clean and invisible look when not hooked up to your RV. 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....

  • Tow Bar Base Plates for 1998 Jeep Wrangler
    I believe you are referring to the base plates. The base plates are vehicle-specific, and provide the mounting point on the vehicle for the tow bar. For the 1998 Jeep Wrangler, you would need part # RM-521424-4 if you have the Rubicon, Unlimited, or Double Tube bumper. If your Wrangler has the U-Channel bumper, you would use part # 1417-1.

    I have a base plate option for you, but unfortunately we do not have an MX base plate kit designed for the 2004 Jeep Wrangler. The correct base plate kit is the Roadmaster EZ4 Base Plate Kit # RM-521424-4. With the EZ4 base plate kit you will need to use the cross bar and if you want to remove the brackets from the car when not towed you will need the Roadmaster Tow Bar Quick Disconnect Kit, item # RM-201.

    The Roadmaster 5250 is the original Falcon tow bar, so it will still work with most Roadmaster base plates, including the Roadmaster Crossbar-Style Base Plate Kit - Removable Arms # RM-521424-4. These are the base plates I recommend using with your Falcon on your 2004 Jeep TJ Rubicon edition. This will work with most bumpers on the Jeep.

The difference is the attachment style the removable arms of the kit have. The EZ4 kit requires you to use the crossbar that comes with the tow bar you use and the EZ5 does not.
