    • 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.

I’ve had Roamaster for years and have worn out 2 tow bars. I’ve never had any problems with them.

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)

as designed. No rust after 2 winters

Installed these on my 2018 wrangler. Awesome instructions! Very happy with how it turned out. The videos in the web site are worth the watch.

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.

Absolutely great, easy install and hitches are hidden when the tow arms are removed , takes seconds by pulling the pin and a simple twist , I highly recommend buying this product, Installed in 2 hours on a 2020 jeep 2 door wrangler.

  • Can You Put A Winch On A 2022 Jeep Wrangler With A Roadmast Base Plate Installed
    Yes, you can install a winch on your 2022 Jeep Wrangler bumper if you have a base plate. Roadmaster Crossbar-Style Base Plate Kit - Removable Arms # RM-521453-4. The base plate mounts to the frame a winch will mount to a plate that is on a bumper or inside some aftermarket bumpers.

  • What Tow Bar Works with the Roadmaster StowMaster Tow Bar for My 2021 Jeep Wrangler Unlimited?
    If you are looking for a great compatible base plate that works with the Roadmaster Stowmaster # RM-501 on your 2021 Jeep Wrangler Unlimited (with factory steel bumper), I recommend the Roadmaster Crossbar-Style Base Plate Kit # RM-521453-4. The Roamaster base plate comes with a hidden-bracket design that comes with a better aesthetic than tow bars that have standard brackets. In order to ensure safety with this system, I recommend the RoadMaster 68" Single Hook, Coiled Safety Cables #...

  • 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...

  • 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...

  • Parts Needed to Flat Tow 2020 Jeep Wrangler Rubicon with Plastic Front Bumper
    We have just what you need! The correct base plate kit you need for your 2020 Jeep Wrangler Rubicon with the plastic bumper is the part # RM-521453-4. This will work great with your Roadmaster Falcon 2 part # RM-520 and Tow Defender part # RM-4750 as well. 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.

  • Can The Crossbar Be Removed From The Roadmaster Falcon 2 Tow Bar
    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.

  • 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,...

  • 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...

  • Parts Needed to Flat Tow 2021 Jeep Wrangler Unlimited and 2019 Ford F-150
    The first thing you'd need is a base plate kit like the Roadmaster part # RM-521453-4 for the 2021 Jeep Wrangler Unlimited and then for the 2019 Ford F-150 you'd want the # RM-524431-4. Then for a tow bar with enough weight capacity for either vehicle the Roadmaster Falcon part # RM-522 would be a really great option. For an easy to use supplemental braking system that's removable the best option is the Blue Ox Patriot part # BLU37TR. Then for wiring the part # RM-15247 would work great.

    You are right that both the Roadmaster Direct-Connect Base Plate Kit # RM-521453-5 and Crossbar-Style Base Plate Kit # RM-521453-4 are confirmed to fit your 2020 Jeep Wrangler Unlimited. The difference between the two models is simply how they are designed to attach to a tow bar.

    The Roadmaster Stowmaster Tow Bar # RM-501 wouldn't be the tow bar to get to flat tow your 2018 Jeep Wrangler Unlimited JL based on the base plate kits that are available for your vehicle. There are only direct connect base plate kits for your vehicle available like the # RM-521453-5 which require tow bars that mount in a hitch on the vehicle like the Roadmaster Falcon # RM-520.

    That's a good question and the only difference between the two Roadmaster base plate kits that fit your 2021 Jeep Wrangler Unlimited are the style of Roadmaster tow bar that connects to them. The Roadmaster Crossbar-Style Base Plate Kit # RM-521453-4 allows you to utilize a Roadmaster crossbar-style tow bar, while the Roadmaster Direct-Connect Base Plate Kit # RM-521453-5 won't allow the use of a tow bar with a crossbar.

    I'd love to help. The first thing you need is a base plate kit confirmed as a fit for your 2018 Jeep JL Wrangler Unlimited. For that we have the # RM-521453-4 from Roadmaster. 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.

  • What is Difference Between EZ5 and EZ4 Roadmaster Base Plate Kits for 2019 Jeep Wrangler
    For your 2019 Jeep Wrangler the EZ5 kit part # RM-521453-5 is a fit and what makes it unique to the EZ4 part # RM-521453-4 is that the EZ5 does not require you to use the crossbar that comes with Roadmaster tow bars like the Falcon 2 part # RM-520. The kit attaches directly to the tow bar whereas with the EZ4 you have to use the crossbar. Not having to use the crossbar makes connecting and disconnecting a bit more easy, but the trade-off is that you can't use a Rock Guard like the # RM-4000...

    Well you're right that it's not EZ1! In fact, Roadmaster quit using the EZ4 and EZ5 names in the baseplates. Now they're called Crossbar-Style and Direct-Connect because it's more clear. The main difference between the two styles, part # RM-521453-4 for the Crossbar-Style and # RM-521453-5 for the Direct-Connect style, base plate kits is how they connect to the tow bar.

    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...

  • Is Crossbar Required to Use Roadmaster Nighthawk Tow Bar w/Roadmaster Base Plates on 2018 Wrangler
    The crossbar, # 910021-00, is not required when using the Nighthawk tow bar, # RM-676, with MX, MS, or EZ5 model base plates. So if your 2018 Jeep Wrangler is the new JL model and you are using base plates EZ5 OR if it is a JK model and you are using # RM-521448-5 or # 1444-3 then you will be good to go without the crossbar. Any other model, EZ, EZ2, EZ4 or XL, and the crossbar is required. The EZ5 for the 2018 JL is # RM-521453-5, or you will need to use the crossbar and baseplates #...
