2021 Jeep Gladiator - Roadmaster Direct-Connect Base Plate Kit - Removable Arms

  • Roadmaster
  • Removable Draw Bars
  • 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 Jeep Gladiator's frame.


Features:

  • 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
    • Pins to connect base plate to the tow bar (RM-910029) are sold separately
  • 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 Nighthawk, 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.

Installed on my 2020 jeep jl sport s with factory plastic bumper and plastic rock guard. Shane’s video was very helpful but I did not like how the metal plate behind the rock guard was cut away and how the rock guard had two big cut outs so I did some modifications. I cut two slots in the metal bracket and added angle brackets for extra support. As a result i did not use the supplied brackets for the rock guard. I created a template for the rock guard which resulted in two small cut outs. A lot of extra time but i am retired so time is relative. I think it looks great.

I bought this base plate kit for my 2022 Jeep Rubicon Gladiator so I could flat tow behind my class a motor home with a Roadmaster Falcon all terrain non binding tow bar. The instructions were easy to follow and went smoothly except drilling the holes. That was my fault because I was using a dull drill bit. See attached photo



by:

Well made, easy to install (provided you use one of etrailer's videos to install it!), non obtrusive. Fits well on my Jeep Wrangler. Just an overall great product!



by:
2020 Jeep Wrangler

Awesome product and great installation instructions. When the draw bar attachments are removed this base plate is barely seen. Highly recommended.



by:
Ram 4500

Perfect fitment and easy installation. Worked out great with our aftermarket bumper. Had to make small modifications but couldn’t be happier. Did a 4500 mile trip right after and paired up great with the falcon 2! I couldn’t believe how fast the shipping was! Thank you etrailer!



by:
2021 Jeep Wrangler

Piece of Cake to install. Video is excellent but some models of Jeep Wrangler are slightly different so pay attention to all the instructions from Roadmaster. in particular, the support for the plastic rock guard is different than those for the metal one.



by:
2024 Jeep Wrangler

Perfect fit. So clean and it has great usability. I am more than satisfied with this wonderful Base Plate.



by:

Well made, easy install following the instruction sheet and etrailer's video. The only problem is that they recommended a 9/16 drill bit which was hard to find for a 3/8 drill and the one that I did buy for $18 would not drill the holes. I ended up using a good 1/2 drill bit that I had and the holes were fine. Installed on 2022 Wrangler.

Still working great after a year and 4,000 miles.



by:
2024 Jeep Wrangler 4xe

Second set on second Jeep, Solid connection, and easy to install, like the removable arms when stowed



by:

Installed, All parts came in the kit, everything fit well.



by:
2021 Jeep Wrangler Unlimited

Great to work with. Would definitely recommend Etrailer.



by:

Roadmaster system is top notch. Installation was not bad. Getting bumper to line up with holes in new bracket was difficult, due to very tight tolerance. We have towed 4 down over 4,000 miles with this set up, no issues at all. Towing 4 down is the only way to go!!



by:

Everything installed perfectly and the instructions where clear. I didn't care for the instruction to cut up the metal rock guard for the crossbar, but otherwise am pleased with the installation result.

We have since travelled 1,200 miles with this set up connected to a Nighthawk tow bar, and are 100% happy with the performance, and are especially pleased with the ease of connection and disconnection.



by:

This is our 2nd tow vehicle with the road master product all is well
Not hooked up but ready to go!

All is working as it should No problems



by:

They look great. Very easy to install great directions and the DIY video made it simple to install. With a twist the tow arms can be added or removed for storage when not in use.
Very satisfied



by:

I installed the tow brackets on my new 2020 Jeep Wrangler. The instructions were excellent. I had no difficulty installing except I failed to follow one instruction to use supplied bolts to reattach part of the Rock Guard Mount. I used the factory bolts which were slightly larger causing interference with my locking mechanism. Maybe a note on that step would be warranted to make sure folks do not make my mistake which resulted in me basically doing the job twice. Tackle the brakes next.



by:

These base plates fit perfect! I have an aftermarket bumper manufactured by Rugged Ridge so some slight modifications had to be made to the winch mounting plate. This consisted of elongating to frame rail holes and adding an additional hole for the top bolts on the base plate. The inside tabs for the winch plate had to be cut back 3/16” in order to fit inside the Roadmaster base plate brackets. It was a tight fit but with some persuasion the winch plate was installed. Looks great!



by:

Installed just like the videos described and comes with all the hardware needed to complete the installation. There is a hole you will need to measure and mark that the video did not cover.



by:

Installation was very simple. Instructions were easy enough to follow. I have an aftermarket Quadratic bumper and they look great. I had to do a little of my own measuring to cut the steel. But easy to install.



by:

Very easy to install and to use. Would definitely recommend it to others.



by:
2022 Jeep Wrangler

Easy to follow instructions.

Great value! Installed myself and performs great! Looks amazing on my 2020 Jeep Gladiator Sport.

  • Recommended Complete Flat Towing Setup for a 2021 Jeep Wrangler Unlimited
    Hey Robert, so for base plates that are going to be compatible with both your Gladiator and your Wrangler I'd recommend going with the Roadmaster Direct-Connect Base Plate Kit # RM-521453-5. These are going to be direct connect base plates that will work great with a tow bar like the Roadmaster Nighthawk All-Terrain Tow Bar w/ LED Lights # RM-676. This tow bar also includes the safety cables needed as well. The last thing you'll need, along with your braking kit is a wiring harness #...

  • Parts Needed to Flat Tow 2022 Jeep Wrangler
    The easiest 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. We don't have a kit that includes everything you'd need for your 2022 Jeep Wrangler but we can help piece it all together. For a base plate kit you'd want the part # RM-521453-5 which is a confirmed and would work great with the Nighthawk tow bar # RM-676. Then...

  • How To Get New Arms For A Baseplate On A Used 2020 Jeep Wrangler
    I believe you have Roadmaster baseplates like # RM-521453-5 instead since the Curt baseplate that's confirmed to fit your 2020 Jeep Wrangler is a different style than what you have pictured. You best bet to confirm would be to remove the underbelly skid plate to get a better look at them to confirm. If they are Roadmaster branded then you'll need to fill out the form under the Installation Details on # RM-ARMS, which I've also attached below and send it in to Roadmaster to get the correct...

  • Comparing Roadmaster & Blue Ox Base Plates For 2023 Jeep Gladiator For Towing With Ready Brute Bars
    For your 2023 Jeep Gladiator Mojave your options are either the Blue Ox Base Plate # BLU53FR which you found or the Roadmaster Direct-Connect Base Plate Kit # RM77VR. The kit # RM-521453-5 you found does not fit your Mojave package. Both the Roadmaster and Blue Ox options are very similar in design with the main difference being Blue Ox requiring you to use safety cables as a safety device. Personally I recommend going with the Roadmaster as their parts I find have better quality and you...

  • Does Installing Roadmaster Invisibrake on 2022 Jeep Wrangler Require Stoplight Switch
    The reason you have to use a Roadmaster Stoplight switch part # RM-751490 when installing the Roadmaster InvisiBrake # RM-8700 on your 2022 Jeep Wrangler Unlimited is because your vehicle's stoplight circuit is not active when the vehicle is off so this is there to provide that signal.

    You will indeed need a "special tool" in order to install the Roadmaster Base Plate # RM-521453-5 on your 2024 Jeep wrangler. The tool they are referring to is a die grinder. This is used to enlarge holes in the frame in order to allow bolts to pass thru. A die grinder would be the preferred tool for this, but it could be done with a drill or file if that is all you have. You should be able to find a decent die grinder at your local hardware store. I have linked the installation instructions...
