Roadmaster Base Plates

  • Removable Drawbars
  • Roadmaster
  • Twist Lock Attachment

Roadmaster's crossbar-style brackets are virtually invisible, easy to mount and simple to remove. Brackets install on your vehicle's frame to provide attachment points for your tow bar.

    • 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
  • Compatible with Roadmaster tow bars with use of quick-disconnect crossbar (910021-00 - sold separately)

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.

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.

2018 Jeep Cherokee

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

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



by:
2019 Jeep Cherokee

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:

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!!!!

Jeep Cherokee

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:
2019 Jeep Cherokee

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.

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.

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.



by:

great fit. a slight cut needed to be made in the bumper bracket to facilitate the round tube to fit through the bracket. but, other than that, it was an easy install took about 2 hours if you include the coffee brakes. this part is highly recommended. Fast shipping. the beast human service. thank you.

Had Base Plate installed today, shop gave me 2.5 hr labor time. I returned just under 2hrs and they were backing my car out the shop. They parked it facing me. I told the Mechanic "That was quick" He said that's because it wouldn't fit. I was disappointed and asked what do I owe you for your labor> He laughed out loud and said it on there, but hard to see. I was so surprised and pleased you have to just about get down on your knees and bend down to see it. took me about 8 min to install everything and connect it to the Tow vehicle. I'm very pleased with it.

  • 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...

  • Roadmaster and Blue Ox Base Plate Kits that Fit 2019 Jeep Cherokee Trailhawk
    Actually both Roadmaster and Blue Ox have two base plate fits for your 2019 Jeep Cherokee Trailhawk. Roadmaster has the crossbar style part # RM-521451-4 as well as the direct connect kit part # RM-521451-5 whereas Blue Ox has the part # BX1143 and the # BX1140 (no longer available) which are both the same style but were intended for different variations of the vehicle but happen to both fit the Trailhawk style.

  • Roadmaster Base Plate Compatible with 2019 Jeep Cherokee TrailHawk
    For your 2019 Jeep Cherokee TrailHawk you can use either the Roadmaster Direct-Connect Base Plate Kit - Removable Arms # RM-521451-5 or Roadmaster Crossbar-Style Base Plate Kit - Removable Arms # RM-521451-4. Both are a confirmed fit for the TrailHawk model. The difference is the # RM-521451-4 will use the quick release bar with the tow bar and the RM-521451-5 will directly connect to the tow bar without the cross brace.

  • 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. I also recommend the following needed equipment required to flat tow your vehicle: Tow Bar: # RM-522. Tow Bar Wiring: # RM-154. Braking System: # HM39530. Safety Cables: # RM-643. There are some additional steps to getting your vehicle flat tow ready so I attached pictures of the owner's manual showing the steps. I highly recommend...

    You are correct that installing the Roadmaster Crossbar-Style Base Plate Kit # RM-521451-4 will require a special tool. The tool you will need is a plastic pop rivet gun. You should be able to find one at a local hardware store or online. I have linked our install video, as well as the manufacturer instructions below.

    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...

  • 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.

  • Guardian Rock Guard Compatibility with Roadmaster Base Plates on 2019 Jeep Cherokee Trailhawk

The better option for you to enable use of both the tow bar and your Rock Guardian # RM-4000 is to use the Roadmaster EZ4 Base Plate Kit - Removable Arms # RM-521451-4. I confirmed with the manufacturer this is the correct fit for your 2019 Trailhawk.
