2021 Jeep Grand Cherokee L - Roadmaster Direct-Connect Base Plate Kit - Removable Arms

  • Roadmaster
  • Removable Draw Bars
  • Twist Lock Attachment
  • Partially Hidden

Designed for use with motor-home-mounted tow bars, the direct-connect brackets are virtually invisible, easy to mount and remove, and they eliminate the need for a quick-disconnect crossbar on your tow bar. Installs on your Jeep Grand Cherokee L's frame.


Features:

  • Direct-connect brackets provide attachment points for your motor-home-mounted tow bar
  • Streamlined design creates supremely clean look
    • No obtrusive quick-disconnect crossbar
    • Hidden brackets sit even farther back than standard brackets
  • 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 motor-home-mounted tow bars only
  • Instructions and mounting hardware included
  • Made in the USA
  • Limited Lifetime Warranty


Note: Roadmaster direct-connect base plates will only work with Roadmaster tow bars that slide into a trailer hitch, such as the Nighthawk, Sterling, Blackhawk, Blackhawk 2, Falcon, or Falcon 2. These base plates will not work with tow bars that require a hitch ball.


The drawbars, or front arms, on this 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 each arm, simply tug the built-in pull pin to disengage the lock, twist the arm back and pull it out of the bracket. 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.

  • Recommended Baseplate For A 2023 Jeep Grand Cherokee 4xe With Roadmaster Falcon 5250 Tow Bar
    Hey Michael, The Falcon 5250 has direct-connect attachment points that hook onto a crossbar, if you remove the crossbar adapter then you'll be able to go with a direct-connect baseplate like the # RM77ZR (models with tow hooks) or # RM76RR (models without tow hooks). If you haven't picked out the rest of your setup then I have the following recommendations: Tow Bar Wiring Kit: Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. This diode kit will splice into your factory...

  • Complete Flat Towing Setup for a 2023 Jeep Grand Cherokee Overland W/ Tow Hooks
    I would personally go with Roadmaster's stuff. They've had a really good track record in my experience and have been an industry favorite for a while. So, for your 2023 Jeep Grand Cherokee you're going to want the Roadmaster Direct-Connect Base Plate Kit # RM77ZR for a base plate and the Roadmaster Nighhawk # RM-676 for a tow bar. This tow bar will easily attach to the base plate using the direct connect brackets, has an integrated LED light for low light conditions, and has an 8K capacity...

  • Will Roadmaster Falcon Tow 2025 Jeep Grand Cherokee Overland
    Hi John; as long as you aren't exceeding that 6,000 lb capacity it won't be a problem so you can use the Falcon to tow your 2025 Jeep Grand Cherokee Overland. Since the Overland has tow hooks the correct Roadmaster Direct-Connect Base Plate Kit is the # RM77ZR. Since you want to use the Blue Ox Patriot # BLU37TR you will also need the 12 Volt Outlet Kit, 20 amps # RM-9332. If you need new wiring the Roadmaster Smart Diode Kit for Variable Voltage LED Tail Lights # RM63MR is the best option...

  • Best Supplemental Braking System For Flat Towing 2025 Jeep Grand Cherokee
    Hello Greg, thanks for reaching out. The correct Roadmaster Base Plate for your 2025 Jeep Grand Cherokee is part # RM77ZR if you have tow hooks and no lower air shutters. If you have lower air shutters and no tow hooks use part # RM75GR. Or if you have no tow hooks or shutters use part # RM76RR. For a brake system, what I recommend is the Demco Stay-IN-Play Duo Flat Tow Brake System for RVs w/ Hydraulic Brakes # SM99251. This is by far our most popular and most durable brake system. It...

  • Recommended Baseplate For A 2023 Jeep Grand Cherokee
    Vehicles with active air shutter will typically have to either have to have them removed or trimmed in order to fit a baseplate and wouldn't be something that would based on the trim level. This happens quite a bit with the Chevy Equinox and isn't a major deal as long as the installer isn't being careless and cutting off more than he needs to. To determine which models are going to have active air shutters you would need to reach out to Jeep to confirm. For a 2023 Jeep Grand Cherokee...
