Roadmaster Base Plates - RM-521424-5

  • Removable Drawbars
  • Roadmaster
  • Twist Lock Attachment

Designed for use with motor-home-mounted tow bars, the direct-connect brackets are virtually invisible, easy to mount and remove, and they eliminate the need for a quick-disconnect crossbar on your tow bar. Installs on your vehicle's frame.


  • Direct-connect brackets provide attachment points for your motor-home-mounted tow bar
  • Streamlined design creates supremely clean look
    • No obtrusive quick-disconnect crossbar
    • Hidden brackets sit even farther back than standard brackets
  • Drawbars attach and remove quickly and easily
    • Arms click to lock in place in brackets
    • Built-in pull rings let you unlock arms so you can twist and remove them
  • 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 motor-home-mounted tow bars only
  • Instructions and mounting hardware included
  • Made in the USA
  • Limited Lifetime Warranty

Note: Roadmaster direct-connect base plates will only work with Roadmaster tow bars that slide into a trailer hitch, such as the Sterling, Blackhawk, Blackhawk 2, Falcon, or Falcon 2. These base plates will not work with tow bars that require a hitch ball.

The drawbars, or front arms, on this base plate kit are supremely easy to mount and remove. Just insert them into the brackets and twist to lock them in place. To remove each arm, simply tug the built-in pull pin to disengage the lock, twist the arm back and pull it out of the bracket. 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 instructions were accurate and the installation went well.


I ordered this Roadmaster tow plate to flat tow my Jeep Wrangler behind my motorhome. Katherine B at etrailer was very helpful in assuring the tow plate was the part I needed. The tow plate arrived in a few days and I installed it myself. It was an easy installation. The tow plate is sturdy and well built and fits nicely under the front bumper. Thank you etrailer and especially Katherine B. Now I have to decide on the type of braking system for my towed Jeep.

Still performing well. No issues.
Bobby U - 06/20/2021


At first I was a little nervous about undertaking this project, but after I started I realized it wasn’t as complicated as I thought. It is important to completely read the instruction and follow them. One thing I eventually did was remove the bumper and the plastic cowling with the word JEEP stamped on it. For me anyway, this made the installation much easier. I didn’t realize it at first, but a screw that held the cowling in place was actually interfering with lining up the base plate and as soon as I removed the cowling the base plate just about fell into it’s proper place. It’s really not a difficult job and doesn’t require a lot of tools, however, be sure to know which tools you will need and make sure you have them on hand. Ordering the Base Plate for my 2004 Jeep Wrangler TJ was easy and quick, the staff I spoke with were knowledgeable and helpful. And, the Base Plate was delivered in just a few days.


What a difference this base plate makes! Brackets remove easily and works like s charm! Great product- my 2006 TJ Jeep is happy& I am as well. We have a few thousand miles of towing on it and still perfect!


Had to replace one that was damaged while 4-wheeling. Great product, love my Roadmaster set-up


Fit perfectly.


thought the over all designee and quality of the base plate is great, your shipping of the part was not to the standard I was expecting and resulted in one of the safety tabs getting bent a bit see photos. not a major problem but not what I expected from etrailer


Works great. Pretty easy to install by myself on my ‘03 TJ


Awesome piece of equipment makes hooking up my jeep to motor home

2003 Jeep Wrangler

I was amazed at how easy it was to install on my 15 year old Wrangler-the mounting instructions were very clear and it fit perfectly! Also impressed with the fast free shipping!


Works great. Easy install


Easy to install and works great


Great product. No problems !


The kit installed as advertised. Have not used it yet. Thanks

1999 Jeep Wrangler

The quick connect pins on this base plate were easy to use and made hooking up and unhooking a breeze. The base plate was easy to install on our 1999 Jeep Wrangler. Worked great with the tow bar we chose.

the based plates work great with the tow bar. EAsy to remove and put on. Love them!
Peggy S - 08/24/2020


Easy to install, drill two holes, six bolts, done.


Great to deal with you. Parts arrived as stated. Got it installed. Only problem was getting the steering box lined up properly. Took it loose when I removed the old brackets.


I received the product as promised and on time


Installed this myself on my vehicle. Needed to drill one hole in the process. Overall very easy to install and fits the vehicle great. I like that it is almost not visible when not in use and arms are removed.


Excellent. Easy to put on my 2001 Jeep. Working with u all I was able to take pictures of my keep and you all got me the exact model I needed. Customer support second to none. Thank you


Thanks I received the order and already mounted the tow bar bracket. Was very easy. I will send a picture once it’s wired up.


Setup was just as stated


Just got it delivered an hour ago. Looks complete, so I will install it in the morning. So we can tow the Jeep and canoe for our camping trip this weekend.

2004 Jeep Wrangler

Fit my 2004 Wrangler perfectly. Some drilling required but not bad. And I'm 65 years old. Etrailer is great!


The bracket was of obviouly excellent construction with a good finish. The accompanying hardware and installation instructions were exceptional. All that was needed was included and carefully explained.

  • Will Roadmaster Direct-Connect Base Plate Kit Fit 1999 Wrangler and Work with Old Sterling Tow Bar
    The Roadmaster Direct-Connect Base Plate Kit # RM-521424-5 is compatible with your 1999 Jeep Wrangler if you have the standard or the double tube bumper. This base plate kit is compatible with your older Sterling tow bar because it has the connections like what you see in the attached picture.

    I went ahead and contacted my tech at Roadmaster, and he confirmed that while he doesn't have the exact measurement below the bumper where the Base Plate # RM-521424-5 installs on a 2004 Jeep TJ, he did confirm that the pins on the baseplate sit 17.25" from the ground. This is with standard 215/75R15 tires. This is super helpful for you to compare with your current setup if you have a lift kit or larger tires installed.

To use your RoadMaster Eagle 8000 towbar with these you will use RoadMaster Base Bar # RM-067. I confirmed this with my technical contact at Roadmaster.

  • Size of Base Pin Holes on Roadmaster RM-521424-5 Base Plate Kit
    As indicated in the provided photo, the holes in the removable drawbars of the Roadmaster # RM-521424-5 base plate kit accept a 3/4 inch diameter pin, such as part # RM-910029 so the holes are actually fractionally larger than 3/4 of an inch. According to Roadmaster, the actual diameter of the hole is right at .77 of an inch.

  • Attaching Roadmaster BlackHawk All Terrain Tow Bar with Blue Ox Collars to EZ5 Base Plates
    I spoke with my contact at Roadmaster regarding your original BlackHawk All Terrain Tow Bar with the Blue Ox specific collars. She stated that the Replacement Swivel Collar # RM-9200-6 that you are looking at is exactly what you need to make your existing tow bar and the EZ5 Base Plate Kit # RM-521424-5 compatible with each other. These collars will simply replace the Blue Ox collars on the tow bar so that it works with any Roadmaster base plates.

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....

  • What Type of Base Plate Does Curt Tow Bar Attach to for 1998 Jeep Wrangler
    This Curt tow bar part # C19745 is designed to be used with the included brackets that would attach directly to a vehicle bumper/frame. It's not a very sophisticated or easy to use setup as most vehicles don't have steel bumpers rated for flat towing. For flat towing a 1998 Jeep TF I'd rather recommend a base plate kit like the # RM-521424-5 and a tow bar like the part # RM-501.

  • Which Roadmaster Base Plate Kit for a 2006 Jeep Wrangler, EZ4 or EZ5
    As long as your 2006 Jeep Wrangler has a double tube bumper either Roadmaster Base Plate Kit # RM-521424-4 or # RM-521424-5 would fit and work well. 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. If it was me I would go with the EZ5 kit as they are easier to connect/disconnect in my opinion. In addition to the base plates, you will also need a compatible tow...
