Features to know about

Built for a Clean Look: Hidden Crossbar-Style Design

If you prefer a front end that looks stock when you’re not towing, this base plate kit does the job. The brackets sit far back on the frame so they stay out of sight, and once you pull the removable drawbars, the setup is virtually invisible. The design keeps everything tucked behind the grille where it’s protected from scrapes and scuffs, so the front of your vehicle stays neat and uncluttered.

Quick to Connect and Disconnect: Twist-Lock Removable Arms

Hook-up and removal are simple thanks to the twist-lock design. Each arm slides into the bracket, clicks in place, and locks with built-in pull rings. When it’s time to unhook, just twist and pull them free—no tools, no fuss. It’s an easy system to manage whether you’re setting up solo or breaking down after a long drive.

Strong Where It Counts: Computer-Cut All-Steel Construction

The all-steel build is precision cut for a perfect fit on your frame, giving you solid attachment points for your tow bar. The black powder coat finish resists rust and corrosion, so it holds up through season after season of road spray and weather. The sturdy structure helps handle towing forces evenly without extra welding or fabrication.

Simple Setup at Home: Bolt-On Installation with Hardware Included

You don’t need to be a fabricator to get this mounted. The kit comes with instructions and all required mounting hardware for a straightforward bolt-on job—no welding required. Once installed, it pairs with Roadmaster tow bars using the quick-disconnect crossbar (910021-00, sold separately), making it easy to tie into an existing towing setup whenever you’re ready to roll.

by:

Came quickly and is very high quality. Great directions/video from road master makes the installation step by step easy to follow.
Skill level is probably at the intermediate level depending on experience.



by:

The #118-3 is a perfect fit on my 1995 Geo Tracker. When you pull off the removable arms you would never know they are there. The Quality is very good easy to put on all you have to do is drill 4 holes the tube on the base plate fits into the tube on the frame of the tracker and with the 2 bolts it is a solid fit. I was worried about the plate nut getting it inside of the frame but it went in easy when you put it over the frame tube and use a thin piece of metal to slide it in place. I’m very happy with it. I probably could of got it on without taking my bumper off but with only 4 bolts holding my bumper on it made it easier

This base plate was a perfect fit for my 2021 Cherokee. I had to do a slight modification. The 2 bolts at the top did not light up until I moved the holes up 116 of an inch. The people at etrailer are the best to work with. Alway a pleasure anytime I order anything from them.



by:

Amazing how much bulk there is to this base compared to the base I used on my Pickup truck. Going to get them mounted on the new vehicle and give them a test soon

Installed the RM-521451-4 on my 2019 Jeep Cherokee Trailhawk. Did it myself. Has been working great. Highly recommend.



by:

Came on time in perfect condition. Installation easy except putting the bumper facia back on. Follow the directions and it works fine. In the year since installation the Jeep Cherokee trailhawk has been towed coast to coast and more locally for more than 6000 miles without any issues. I would recommend this product



by:

This was the other part of my order to install the Roadmaster Stowmaster tow bar on my new Jeep.



by:

Fit perfectly. Installation easier then I expected. Snapping the front bumper facia from my 2019 Jeep Cherokee a little more difficult then the instructions would have you believe. Takes some effort to pop it away from the vehicle. That is the only snag.



by:

I've purchased from etrailer for many years. They are always great and this was no exception. After a little confusion with one rep I worked with another and have just received all I need for a new flat-tow package for my RV/Jeep. Meghan was able to help me figure out how to use my existing tow bar with an adapter, which saved me a good bit. I highly recommend etrailer!!!!



by:

i suspect that the kit was for a 2018 cherokee for a couple of reasons. The first is the top 2 holes of the brackets were 3/16th too low to align with the holes on the jeep. i was able to elongate the bracket holes to line up. The rest of the holes lined up. The elongated holes worked fine. the valance was held on by 20 or so white locking clips. nothing like the directions showed. fortunately i was able to figure out how to remove the clips. the workmanship on the brackets was nice. i would check out where those top 2 holes are supposed to be.....John



by:

Good fit, works well. Very happy with the base plate after 1st year of use.
etrailer staff was very helpful with my questions, making certain I got the base plate that was right and advice with minor problems I had with installation.



by:

This is the adapter kit i needed for my 2019 Jeep Cherokee to flat tow it behind my Class A Motorhome. At the time I first ordered this kit the factory still had to finish the design process as we had purchased the Jeep when it came out in 2018. It took about 6 weeks for the factory to call me to say it was done and could be ordered. My RV mechanic installed it and it went very well according to him. I towed the Jeep this weekend and it worked flawlessly. It replaces the tow hooks on the front of the Jeep. Everything arrived very quickly and in perfect order from etrailer.



by:

The crossbar is functioning great and I feel confident while flat-towiny Cherokee. I've done over 3,000 miles so far and many more to come!

  • Flat Tow 2021 Cherokee TRAILHAWK 4X4 Sport Utility
    # RM-521452-4 is not a confirmed fit for your vehicle because it excludes the Trailhawk editions. I recommend # RM-521451-4 which is a confirmed fit instead.

  • Needed Steps Before Flat Towing 2019 Jeep Cherokee
    You will definitlely want the steering wheel to be unlocked when flat towing your 2019 Jeep Cherokee, but you will want to follow the specific steps outlined in the vehicle's owners manual for what needs to be done with the ignition and transmission. I took a look at the online version of the manual and found the following procedure (I do also recommend verifying this in your copy of the manual): 1.

    Yes, the two Roadmaster base plate kits part # RM-521451-5 and # RM-521451-4 are a fit for the 2022 Jeep Cherokee Trailhawk. 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. The most popular compatible tow bar is the Falcon All Terain, # RM-522. This has non-binding arms which makes the setup very easy to connect/disconnect. For lighting/safety cables, locks, and covers for the tow bar...

    Hello Jonnsia, thanks for reaching out. The Stowmaster tow bar is typically not something I recommend since it isn't non-binding and it can be a pain to deal with. If you can get a really good deal on it, it would be enough to support your Jeep. But unless you really want to store the tow bar on the front of your Jeep, there are way better option out there like the Roadmaster Falcon 2 # RM-520.

  • Picking Between Towed Vehicles 2020 Jeep Cherokee Trailhawk 2020 Honda Accord and 2021 Ford Escape
    All of the vehicles you mentioned can be flat towed but the 2020 Honda Accord Sport can only be flat towed if it's a manual transmission model. So assuming that's not something you'd want to mess with that leaves the 2020 Jeep Cherokee Trailhawk and the 2021 Ford Escape Hybrid which would both require about the same components to flat tow so one wouldn't have advantage over other in that regard. I'd pick between these two based on which you'd rather have with you at the campsite or to own...

  • Will the Roadmaster Guardian Work With Roadmaster Direct-Connect Base Plates On 2020 Jeep Cherokee
    I do have a vehicle protector that can be used with the Roadmaster Direct-Connect Base Plate Kit part # RM-521451-5 on a 2020 Jeep Cherokee but the Roadmaster Guardian Rock Guard part # RM-4000 would require the Roadmaster Crossbar-Style Base Plate Kit part # RM-521451-4. There are no adapters or conversion kits for this. Instead, I recommend the Roadmaster Tow Defender Protective Screening part # RM-4750 which will work just fine with the Roadmaster Direct-Connect Base Plate Kit.

    The base plate I recommend for your 2021 Jeep Cherokee Trailhawk is the Roadmaster Direct-Connect Base Plate Kit - Removable Arms # RM-521451-5. I recommend this Roadmaster base plate because the Direct-Connect option makes it very easy to connect your tow bar to the base plate. You will also need a tow bar to link your motorhome to your Jeep Cherokee. The tow bar I recommend is the Roadmaster Falcon 2 Tow Bar - Motorhome Mount - 2" Hitch - 6,000 lbs # RM-520.
