    • Crossbar-style brackets sit far back for a supremely clean look
  • 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

The drawbars, or front arms, on the crossbar-style series 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, 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.

This was a straightforward install. The instructions were easy to understand and follow. All the necessary parts and hardware were included. It is pretty well hidden once installed. I highly recommend this base plate and etrailer.

I have towed the Jeep several times with no issues. So far so good.

2023 Jeep Wrangler 4xe

Ordered Product on Saturday afternoon, delivered on Wednesday, Installed on Friday. My 23 Wrangler Sahara 4Xe did take the spacer and washer on each side of the frame and was no problem getting them to fit. The lower passenger outside nut that holds on the bumper will not tighten down all the way, the flange of the factory nut gets caught in a slot in the base plate on that side. Will look into a standard nut to see if that will work - it is tight against the slot and holding.

great kit to add a baseplate to my 2019 jeep wrangler. It takes several hours for one person to install, but if you follow the instructions and watch the video it's straight forward and easy to install.

2022 Jeep Gladiator

5 hours into install. Not the kits problem as I am using a ratchet, don't have an impact wrench. Biggest problem I had was nuts that went up into the frame. Very frustrating. Not sure why couldn't use a long bolt and go straight through to the hole on the other side. Instructions for the cut on the plastic skid plate are a little vague as is the video. All in all, pretty smooth install.

Works great easy to hook up and unhook.

easy to install. After 1 year not rusting at all. On a wrangler they are almost invisible compared to Blue Ox which a friend has and the entire set up is on the front end 24/7 (cross bar)

2019 Jeep Wrangler

Great product and thanks to etrailer.com for the excellent videos detailing how to install the Demco Stay-In-Play Duo braking system. As a result of watching all of the available videos, I learned that there where a couple of different ways to install the system in our Jeep Wranglers. The first installation I did was in our 2019 Wrangler and that was super easy following the one video on your website. The second installation of the system was not as easy because our 2021 Wrangler has a manual transmission and required having to drill a hole in the firewall/floor board to run the wiring and vacuum tube from the passenger compartment to the engine area. If etrailer.com ever has an installation on a Jeep Wrangler with a manual transmission to perform, hopefully they will video tape that installation to guide customers with Jeeps with manual transmissions. I think etrailer.com's idea of mounting the control box on the fuse box is by far the cleanest and easiest way to install the Demco braking system.
I also followed etrailer.com's videos for installing the brake light system and the base plate on both our Wranglers and could not be happier with them. Thanks etrailer for all you offer.

2020 GMC Terrain

Recently I ordered a Roadmaster Sterling All Terrain Tow Bar (RM-576) and a Roadmaster Crossbar-Style Base Plate Kit (RM-521453-4). The included Roadmaster installation instructions were very good and easy to follow. A few minor questions came up during the installation, but eTrailer's excellent installation video by Shane cleared up any confusion. Overall the installation of both the base plates and the tow bar was pretty simple and straight forward. I think eTrailer's product and installation videos are a great help in picking the right item and installing it.



by:

Great product. This is the 4th unit I have purchased and used on different vehicles. When I purchased the wrong unit, etrailer replaced it with the correct one. Between the installation instructions that come with the kits and the available videos on the website, installation is relatively simple. I would and have recommended etrailer to a lot of people.

  • Flat Towing Equipment Recommendations A 2021 Jeep Wrangler Unlimited
    Before flat towing your vehicle you'll need to read the owner's manual to ensure your vehicle is capable of being flat towed and follow any necessary steps it's lists to be ready to tow. To flat tow your 2021 Jeep Wrangler Unlimited you'll need a tow bar, tow bar wiring, base plates, safety cables, and a braking system. I have the following recommendations for you below: Tow Bar: etrailer SD Non-Binding Tow Bar for Roadmaster Crossbar-Style Base Plates - 2" RV Mount - 6K Item # e44ZR....

  • Does Roadmaster Falcon Tow Bar # RM-522 use Crossbar
    The Roadmaster Falcon Tow Bar part # RM-522 that you referenced does not come with a crossbar. You'd use it with a set of crossbar style Roadmaster base plates. Which for your 2021 Jeep Wrangler Unlimited you'd need the part # RM-521453-4. The crossbar is the part # 910021-00.

    You can use the Roadmaster Base Plate kit part # RM-521453-4 that fits your 2018 Jeep JL Wrangler with your Duncan Towmatic II tow bar but you do have to use an adapter # RM-038. For lighting/safety cables, locks, and covers for the tow bar we have the Roadmaster Falcon All Terrain kit part # RM-9243-1 which comes with all of that as one part number. The diode kit that comes with this allows you to splice into the taillight wiring so that your RV controls the vehicle taillights and does...

  • Is Direct Connect Roadmaster Base Plate as Strong as Crossbar Base Plate for 2020 Jeep Wrangler
    This is a good question. So it really comes down to preference between the Roadmaster base plate kits that have the crossbar and the ones that do not. The kits like you have # RM-521453-5 without the crossbar are actually reinforced more at the welds and have thicker brackets to compensate for the lack of support from the crossbar like # RM-521453-4. Having hooked up both styles I really prefer the kit you have as the connection is just much easier and there's one less thing to keep track...

  • Difference Between Crossbar-Style and Direct-Connect Base Plate Kits for 2020 Wrangler Unlimited
    The Roadmaster Direct-Connect Base Plate Kit # RM-521453-5 is the upgraded version of the Crossbar-Style Base Plate Kit # RM-521453-4 for your 2020 Jeep Wrangler Unlimited. The direct-connect has the same basic installation and removable arms just like the crossbar-style option but the direct-connect is much easier to use out in the field because you connect the arms independently of each other instead of having them linked with a crossbar. Because of this I recommend going with the direct-connect...

    The Roadmaster Crossbar-Style Base Plate Kit part # RM-521453-4 and Roadmaster Direct-Connect Base Plate Kit part # RM-521453-5 are both great options for a 2021 Jeep Wrangler Unlimited. The only difference between the two is the arm design.

    The biggest difference between the Roadmaster Crossbar-Style Base Plate Kit # RM-521453-4 and the Roadmaster Direct-Connect Base Plate Kit # RM-521453-5 for your 2021 Jeep Wrangler Unlimited is going to be the style of tow bar that you can use.

  • What is the Difference Between The Roadmaster EZ4 and EZ5 for My 2021 Jeep Wrangler Unlimited?
    The only difference between the Roadmaster EZ4 # RM-521453-4 and the EZ5 # RM-521453-5 is that the EZ5 includes the direct connect brackets that allow you to attach the plates to a motorhome-mounted tow bar like the Roadmaster Falcon # RM-522. This ultimately makes for a faster setup. On the EZ4, you need to purchase an additional part # 910021-00 in order to have that same efficient feature. Given that the EZ5 includes the quick disconnect capability, I recommend going with that tow bar...

  • Best Parts Needed to Flat Tow 2019 Jeep Wrangler JL Recommendation
    Thanks for the picture of your 2019 Jeep Wrangler! Based on that we know that you do have the plastic bumper so the Roadmaster base plate kit part # RM-521453-4 is the correct fit and will work great. It's the easiest to use option to so I think you'll like it the best. The lightest weight and easiest to use compatible tow bar is the aluminum Roadmaster Nighthawk part # RM-676 which would be your best option for sure. The # SM99243 is also a really great option so you are on the right...

  • Difference Between Roadmaster EZ4 and EZ5 Base Plates for 2020 Jeep Wrangler Unlimited
    Both the Roadmaster EZ4 # RM-521453-4 and EZ5 # RM-521453-5 Base Plate Kits are confirmed to fit your 2020 Jeep Wrangler Unlimited, however I do recommend the EZ5 # RM-521453-5 because of how it attaches to the tow bar. Unlike the EZ4 mounts that require a crossbar to connect to a Roadmaster tow bar, the EZ5 design lets you directly attach to the tow bar arms for an easier hookup and cleaner appearance.

Then for wiring you'd need the part # RM-146 as a 6-way to 6-way coiled adapter and then for the wiring and diodes part # RM-152 and you'd be set.

I have found the if it is not in the kit it will be red. As far as the torque specs, I am an installer and we go by the manufacturers recommendations on the instruction sheet.

    For your 2019 Jeep Wrangler Unlimited JL with the adaptive cruise control (ACC) you can use the Roadmaster EZ4 Base Plate Kit part # RM-521453-4 which is a confirmed fit. If you have a Blue OX tow bar then you can still use it with this base plate kit but you will also need the Roadmaster Tow Bar Adapter part # RM-032. The issue with ACC is in regards to the location of the sensors/brackets which Roadmaster has deemed is not an issue while using the above base plate kit.

    Hey Chad, so unfortunately there is not a way to use the EZ hook safety cables with a Direct-Connect base plate like the # RM-521453-5. The EZ hook safety cables are only compatible with the EZ Hook Safety Cable Anchors # RM-910653, and these anchors are only compatible with the Roadmaster Crossbar-Style base plate.

  • 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,...

This is one the easiest setups to use out there so it's a really solid option I would recommend.

    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...

    Since you have a crossbar-style baseplate with the # RM-521453-4 you would need to fill out the # RM-ARMS form linked below and reach out to Roadmaster to get replacement direct-connect arms in order to drop the crossbar. Once the arms are replaced you'll be able to take the crossbar off the Falcon 2 and just use the quick-disconnect attachment points on the tow bar to connect directly to the baseplate.
