2021 Jeep Wrangler Unlimited - Roadmaster Direct-Connect Base Plate Kit - Removable Arms

  • 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 Jeep Wrangler Unlimited'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:

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:

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.

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



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!

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:
2021JeepWrangler Unlimited

Great to work with. Would definitely recommend Etrailer.



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:

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:

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:

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:

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.



by:

I had to go pick up this package. I drove 30 miles to pick it up. The box is open. I hope parts are not lost.

  • Does Roadmaster Direct-Connect Base Plate Fit 2021 Jeep Wrangler Unlimited
    I just checked with Roadmaster for you and can confirm that your 2021 Jeep Wrangler Unlimited is compatible and will work with the Roadmaster Direct-Connect Base Plate Kit # RM-521453-5. These base plates will also work with the tow bar you mentioned, which is a great choice, the Roadmaster Falcon All Terrain, Non-Binding Tow Bar # RM-522. Along with the base plates and tow bar, there are some other parts you will need for your '21 Wrangler if you don't have them, which I'll list for...

  • Recommended Base Plate Kit for a 2020 Jeep Gladiator Rubicon
    The base plate kit that I recommend for a 2020 Jeep Gladiator Rubicon is the Roadmaster Direct-Connect Base Plate Kit part # RM-521453-5. This will then pair perfectly with the Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar part # RM-676 which is what I recommend. Please note, any aftermarket winches could interfere with the base plate depending on location so you will need to keep this in mind during installation. There aren't any options designed for aftermarket winches so you...

  • Do Base Plates for 2021 Jeep Wrangler Unlimited with Factory Steel Bumper Alter Skid Plate?
    Each of the base plates that fit your 2020 Jeep Wrangler Unlimited (with factory steel bumper) do require the altering or even replacement of the skid plate (also sometimes called a rock guard). The base plate kit I recommend because it will allow the skid plate to be trimmed but not outright replaced is the Roadmaster Direct-Connect Base Plate Kit # RM-521453-5. I went ahead and linked a video to a 2020 Wrangler model to give you perspective. In addition to the base plate kit, you will...

  • Recommended Roadmaster Base Plate for 2019 Jeep Wrangler Unlimited with Factory Bumper
    For your 2019 Jeep Wrangler Unlimited with standard bumper I suggest Roadmaster's EZ5 Base Plate # RM-521453-5 because its streamlined design and removable draw bars mean a cleaner appearance on the Jeep when you're not towing it. This USA-made base plate includes all hardware and it is directly compatible with your BlackHawk 2 all-terrain tow bar # RM-422. Installation instructions are linked for reference.

  • How to Install Roadmaster Direct-Connect Base Plate Kit on 2020 Jeep Wrangler Unlimited
    The long and short of installing the Roadmaster Direct-Connect Base Plate Kit # RM-521453-5 on your 2020 Jeep Wrangler Unlimited is that you'll need to remove the front bumper (disconnecting any electrical parts connected to the bumper) and then the base plate kit mounts directly to your frame. You will need to also make some cutouts in your bumper fascia for the removable arms to fit through. While I could copy out the entire installation instructions, anything I put here wouldn't do...

  • Will The Roadmaster Direct Connect Base Plates # RM-521453-5 Connect To A Demco Dominator Tow Bar
    There currently are no adapters available to connect the Roadmaster Direct-Connect Base Plate Kit - Removable Arms # RM-521453-5 to your Demco Dominator Tow Bar # DM9511008 so instead I recommend going with the RM-521453-4 which is the same bracket but with different style arms which will allow you to use the Roadmaster Tow Bar Adapter # RM-032 and connect to the Dominator tow bar. If you don't want to have to use an adapter you can use a Demco branded base plate like the # DM9519336...

    In addition to your Falcon # RM-522 All Terrain tow bar, you'll need base plates, safety cables, a wiring harness, a supplemental braking system and possibly a high/low adapter. For a base plate, use the Roadmaster Direct Connect Base Plate, part # RM-521453-5 and the # RM-643 safety cables. For wiring, the popular choice is # RM-15267. For a braking system, some prefer a drop in system like the # RM-9400 Even Brake, but unless you swap vehicles every year or two you'll probably be happier...

  • Comparing Direct-Connect and Crossbar Base Plates for 2018 Jeep Wrangler JL Unlimited
    The difference between the Roadmaster Direct-Connect Base Plate Kit # RM-521453-5 and Roadmaster Crossbar-Style Base Plate Kit # RM-521453-4 is how tow bars attach. As the name suggests, you will connect your tow bar straight to the direct-connect base plates while the crossbar style will require you use your tow bar's crossbar or quick-disconnect. This makes the direct-connect the easiest base plate to connect to and disconnect from. Because of that, for your 2018 Jeep JL Wrangler Unlimited...

  • Recommended Tow Bar Wiring For Flat Towing 2021 Jeep Wrangler Unlimited
    For tow bar wiring to flat tow your 2021 Jeep Wrangler Unlimited behind your 2019 Ford F-450 I recommend the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 which will add a 6-way connector to the front of your Jeep and the included 7-way to 6-way cord will plug into the 7-way connector on your tow vehicle. The included diodes will protect your Jeeps factory wiring from any backfeed or damage. You will still need a base plate kit, tow bar, safety cables, and supplemental...

  • Can The Roadmaster StowMaster Tow Bar Work With Direct-Connect Style Baseplates

If you haven't picked out the rest of your flat towing components then I have the following recommendations for you as well: Tow Bar Wiring Kit: Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267.

  • Roadmaster EZ 4 or EZ 5 Base Plate for Flat Towing Vehicle Behind RV
    The difference between the EZ 4 # RM-521453-4 and the EZ5 # RM-521453-5 base plate kits is that the EZ 5 is a direct connect with no crossbar and the EZ 4 doesn't use a crossbar. Essentially, you'd want to match the base plates to the tow bar you're using. This involves how the tow bar attaches to the base plates. The Falcon 2 # RM-520 tow bar uses a crossbar, therefore you'd want to use the EZ 4 base plate. For a tow bar such as the # RM-677 Roadmaster Nighthawk that doesn't use a crossbar,...

That being said, a winch that mounts on the top side of your bumper is probably the safest route to go for compatibility.
