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.1392216
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.1236553

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.1046400
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.1245762

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)1277163

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.851189

The Roadmaster Base Plate Kit # RM-521453-4 referenced in your question does not feature a mounting space for a breakaway switch. This is really the case for any of the base plate kits we have available as it's really best to attach the breakaway switch and bracket directly to the vehicle and not an external attachment like the base plates or tow bar. On your 2018 Jeep JL Wrangler your best option may be to attach it to the underside of the front fascia/bumper. view full answer...
The 2020 Jeep Wrangler JL does not have a steering wheel lock. In 2008 Jeep did away with that function so if your plan is to flat tow your JL you do not need to worry about the steering wheel being locked. There are very specific instructions in your owners manual about flat towing though that you need to follow.
The Roadmaster base plate kit part # RM-521453-4 is the correct kit for your JL though. I attached an install video for more info on the kit as well. view full answer...
The Roadmaster Direct Connect Base Plates # RM-521453-4 are going to install in the area that the skid plate is located, not on top of the bumper or in front of it, which is where I'm assuming most of winches are going to be mounted. If you've got an aftermarket bumper where the winch is mounted behind the bumper area and the rope winch has rollers on the front, it still isn't going to interfere.
I've linked our installation video of these base plates for you to have a look at, as well. view full answer...
The Roadmaster base plate kit part # RM-521453-4 does fit your 2018 Jeep JL Wrangler Unlimited that has the factory steel bumper with the winch built into it. view full answer...
The Roadmaster Crossbar-Style Base Plate Kit # RM-521453-4 we will only have as an entire kit. The individual mounts are not available with the arms. view full answer...
Yes, you can install a winch on your 2022 Jeep Wrangler bumper if you have a base plate.

The base plate mounts to the frame a winch will mount to a plate that is on a bumper or inside some aftermarket bumpers. view full answer...
All warranty registrations like your Roamaster Crossbar-Style Base Plate # RM-521453-4 (521453-4) is completed through the manufacturer of that product. You will need to register your baseplate through Roadmaster. view full answer...
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... view full answer...
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,... view full answer...
Both the Roadmaster Direct-Connect Base Plates # RM-521453-5 and the Crossbar-Style Base Plates # RM-521453-4 will fit your 2020 Jeep Wrangler Unlimited perfectly (as long as you have the factory plastic or steel bumper). The difference between the two models focuses on how they actually attach to the tow bar.
The Direct-Connect Base Plates, which is what I recommend, can attach directly to the tow bar arms without the need for a separate crossbar component that can be a bit of a pain... view full answer...
The EZ5, part # RM-521453-5 won't utilize the crossbar on the tow bar, which leads to a quicker, cleaner installation, hook up and removal process. If you're using a motorhome mounted crossbar, this is what you should use unless you have the Sterling, Stowmaster or Tracker tow bars or use or intend to use the Guardian Rock Shield, part # RM-4700 Tow Defender. If you have one of those tow bars or wish to use those rock shield products, you'll need the EZ4, part # RM-521453-4. view full answer...
The reason the Roadmaster Direct-Connect Base Plate Kit # RM-521453-5 for your 2021 Jeep Wrangler Unlimited does not use a crossbar for the tow bar is due to the design of the removable arms that connect directly to the tow bar instead of requiring a tow bar. There is not a hidden cross bar on the base plate.
You are correct that the crossbar adds strength to the system, but on Jeeps like yours direct connect base plates are plenty strong and are the most common option due to them allowing... view full answer...
Whenever available I recommend people go with the Direct Connect Roadmaster base plate kits like the part # RM-521453-5 over the crossbar style # RM-521453-4 that fits your 2021 Jeep Wrangler Unlimited as they overall are easier to use and require less parts to remember (the crossbar). Both are also perfectly compatible with your Roadmaster Falcon tow bar # RM-520. view full answer...
Yes, the Roadmaster Guardian Rock Guard # RM-4000 will absolutely fit the EZ4 Roadmaster Crossbar-Style Base Plate Kit # RM-521453-4 that you have on your 2018 Jeep JL Wrangler. The Guardian is going to do a superb job of keeping your Wrangler from any unnecessary damage when you're towing.
I've added a link to a video review of the Guardian Rock Guard for you to check out as well. view full answer...
Yes, the Roadmaster Stowmaster 5000 tow bar you have is perfectly compatible with the Roadmaster base plate kit # RM-521453-4. The crossbar of your tow bar would connect to the removable arms of this base plate kit and you'd be set. view full answer...
Roadmaster does have a base plate that will work, part # RM-521453-4. You'll also need the # RM-038 Duncan tow bar to Roadmaster Base Plate adapter. The reason we don't list the coupler style tow bars as being compatible is that the EZ4 type base plate drawbars need to be twisted 90° to remove, which isn't easy when the adapter is bolted on.
In other words, according to Roadmaster, it WILL work, it just won't be super-easy to remove the base plate draw bars as you'll need to unbolt the... view full answer...
The Roadmaster Crossbar Base Plate part # RM-521453-4 is a fit for your 2021 Jeep Gladiator and is compatible with all Roadmaster tow bars including the Stowmaster # RM-501 you have. view full answer...
The # RM-576 tow bar will connect to the # RM-521453-4 with no issues and to your 2021 Jeep Gladiator. The # RM-521453-4 base plates will come with new twist-lock arms. If the arms you have for your Honda CRV are Roadmaster then they should also work with your base plates. view full answer...
Since you have a Roadmaster tow bar already that uses the crossbar setup you'd just need the base plate kit part # RM-521453-4 for the 2021 Wrangler JL and you'd be set.
If you don't have lighting already you could use the part # RM-15247 as well. view full answer...
If you are going to flat tow with a Roadmaster Nighthawk tow bar, you will need to use accessories that are compatible. The base plate I recommend is the Roadmaster Crossbar-Style Base Plate Kit - Removable Arms, part # RM-521453-4. With this baseplate and towbar combination you will have everything you need to flat tow your Jeep Wrangler Unlimited.
The last thing you will need is a rock guard that can attach to your tow bar mounting bracket. My choice is the Roadmaster Guardian Rock... view full answer...
The Roadmaster Guardian Rock Guard # RM-4000 is compatible with the Roadmaster Crossbar-Style Base Plate Kit # RM-521453-4. The rock guard will still attach to the base plate kit. I have included a picture of the rock guard installed on the Roadmaster Crossbar-Style Base Plate Kit # RM-521453-4 and I have linked the instructions for the rock guard so you can see how it would install. view full answer...
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... view full answer...
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 Direct-Connect Base Plates can connect directly to the arms of a compatible Roadmaster tow bar, without the use of a crossbar like what comes with the Falcon 2 # RM-520 or directly to a model that doesn't... view full answer...
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 former has crossbar style arms meaning they are designed to be used with a tow bar like the Roadmaster Falcon 2 Tow Bar part # RM-520 and the latter has direct-connect arms meaning they are designed to be used with a tow bar like the Roadmaster... view full answer...
