If you like the look of a clean bumper when you’re not towing, this base plate keeps things tidy. The hidden bracket design sits back on the frame so the front stays uncluttered. Once the drawbars are removed, the brackets are virtually invisible and protected inside the grille area. It’s a simple way to keep your setup strong without anything hanging out front.
You don’t need to fight with pins or alignment every time you hook up. The removable drawbars slide in and twist to lock securely in place. When you’re done towing, just twist again and pull them free using the built-in pull rings. It’s quick, reliable, and gives a solid locked-in feel that makes connecting your tow bar straightforward every time.
This base plate is all about strength and long-term reliability. The computer-cut, all-steel construction delivers exceptional durability while spreading towing forces across the frame. A black powder coat finish resists corrosion so it can handle years of road use without flaking or rusting. It’s a tough setup built for dependable towing mile after mile.
If you like tackling projects yourself, this kit makes it manageable. The base plates mount directly to the frame with no welding required, and everything needed for installation comes in the box—hardware and clear instructions included. Integrated mounting points make it simple to add an electrical connector plug or bracket (sold separately) for a neat, finished look once everything’s installed.
Already using a Roadmaster tow bar? This kit works with Roadmaster models when paired with the quick-disconnect crossbar #910021-00 (sold separately). That flexibility makes it easier to integrate into your existing towing gear without needing a full replacement. It’s a straightforward way to keep using what you already have while upgrading to a cleaner, more hidden mount design.
The drawbars, or front arms, on the crossbar-style series base plate kit are easy to mount and remove. Once removed, the remaining brackets are virtually invisible. On most automobiles, brackets are mounted within the grille for protection from scrapes and scuffs.

Etrailer is always good to work with.
Delivery was fast. Install went well and was easily completed. Quality products.
Easy to install. Works as advertised. Starting to rust after only 1 year.
Fit perfectly in the Grand Cherokee and the instructions were perfect.
Works great easy installation with ease! No complaints!
Great service from etrailer. I had ordered and received the wrong part. I contacted etrailer and they verified the correct part I needed and shipped it right out.
The products purchased were to allow me to tow my new Jeep Grand Cherokee behind my motorhome. Actually I had purchased a similar setup from you Five years earlier for my 2014 Jeep Cherokee Trailhawk. Both worked as advertised and I was very satisfied.
Just what I wanted. Roadmaster is the b est!
Quality made! Great installation instructions and ETrailer video. Can't go wrong.
Just finished installing this base plate on our 2020 Jeep Grand Cherokee. The install went smoothly with the help of all the etrailer videos. Every thing fit and all the parts were there. Thanks etrailer
Tim M was great to work with, parts came very fast and installation was easy with the instructions that came with it. Will be going back to etrailer again for my towing needs. The salesman was very helpful when it came to knowing the products.
Patrick was a pleasure to deal with.he verified the proper and required components,followed up getting them shipped quickly and free,no sales tax.highly recommend!!!!
Just received RoadMaster Baseplate Kit (-4), Falcon 2 Tow Bar, Diode Taillight Kit and the Wireless Braking Kit for my 2016 Jeep Grand Cherokee Summit. Arrived after only two days! All packages arrived in good shape!
Thanks for the quick delivery. The base plates mounted exactly as per the instructions given. Real easy.
The next time I need new base plates for a different vehicle I'll make sure to contact you.
Thanks again.
Installation was straight forward. Online video was a great addition to the included instructions. Brackets have worked well and are easy to set up for towing
The base plate fit fitment is great. However, due to 2012 Jeep Grand Cherokee Summit manufacturing tolerances, there was a little shimming required on driver side radiator support bolt up on my installation (1/8" flat washer was used). Other then that, installation was a breeze.
Product installed easily hardest part was finding drill sharp enough to drill holes. Took about 4 hrs at a 75 year olds pace.
Looks nice and fit my existing tow bar with no problems. You may want to remind buyers they need a plastic pop rivet tool, not easy to find in local auto stores. I took advantage of my friend who owns a body shop, it took 2 minutes.

Still towing my car works great. Very satisfied only problem I had was my wife panicked when she saw front of car on lawn while I installed brackets.
E trailer representative was very helpful and knowledgeable. The parts fit perfectly just as described and have worked. Perfect I am pleased with my purchase and the service and information given to me by the e-trailer representative. I have recommended e-trailer to other friends that have had the exact same experience that I have had.
I ordered an RM -521440-4 base plate for my Jeep Grand Cherokee.
Talked with sales and they were very helpful and knew their products.
The price was good and it was delivered in a few days.
Good company to do business with.

Since the base plate install we have towed our Jeep to California and back without any issues. Good quality and easy to use.
One year ago I purchased the equipment to tow my Jeep Grand Cherokee 4 flat behind my motorhome from etrailer. I received the items within 4 days, and was able to do the install myself thanks to the fantastic instructional videos provided by etrailer.
I have towed it from Iowa to Colorado, and several shorter trips. It is easy to
hook up/unhook and tows fantastic. I went with the Roadmaster Sterling tow bar as well as the roadmaster crossbar with removable arms. I would HIGHLY recommend this setup! I also put the roadmaster diode wiring set in the Jeep to use the tail lights. Works flawless! I have used etrailer for several items and have always been completely satisfied. Preston was super helpful in helping me choose the best equipment for my application! Can't go wrong with etrailer!
This is an nice unit and the instruction included were spot on. It is very scary to rip the front end of your toad off to install a tow kit. But, nothing went wrong and the parts are great. Should be easy to remove and install when needed.
One improvement would be a better way to cut out the two grill parts for the tow extensions. I finally toss the originals and left open holes. It looks find. And bought new closures for the time that I decide to change the rig. If Road Master had produced a templant, I might have had something that I would have used. as it was, I screwed up the closure too much to use.

they work great. I changed to a 2018 Jeep Grand Cherokee and had the dealer switch over. Still work perfectly. Using them again in Oct.
I ordered this base plate to be installed on our 2020 Jeep Grand Cherokee Limited to allow it to be used with a Roadmaster Tow Bar that we purchased originally in early 2000 to tow our 2000 Jeep Grand Cherokee. Yes, 20 years later we are back into RVing and wanted to tow our 2020 Jeep behind our new Jayco Seneca Super-C motorhome. The only difference between 2000 and 2020 is the fact that we needed a brake activation system for our 2020 setup, something that wasn’t required in 2000. etrailer also sold us the Roadmaster Invisi Brake operating system which we had our local welding fabricator (also RV hitch installation expert) instal. Everything works perfectly and safely. Thank you etrailer!

Excellent! We have towed the Grand Cherokee with it for over 17,000 miles since installation, with no operational issues. From NW MT to west coast of WA, to Rockport, TX, to Duluth, MN and back in three separate trips.
Easy to install the videos you have are a great help, 2012 Jeep Grand Cherokee
The Base Plates are performing as expected, unfortunately chipping paint has plagued these Base Plates. This chipping paint has occurred along both of the leading edge of where the tow bar mounts. This has not been caused from abuse/misuse, it started happening soon after began using. Should not have happened so soon.
This was my 4th install for a dingy (with 4 wheel flat towing) in the last 20 years. This install is for a 2018 Jeep Grand Cherokee, Overland. The New ROADmaster 90* twist & lock removable base plates are REALY Awesome! So much much easier & faster than installing & removing locking pins! One picture shows a Brush guard from ROADmaster no longer available.
