The Roadmaster Baseplate Kit with Factory Steel Bumper/Winch (Part #521463-4) is designed for the 2024 Jeep Wrangler equipped with the factory steel bumper and winch. This crossbar-style baseplate kit facilitates flat towing by providing a secure connection between your Jeep and a motorhome-mounted tow bar.
Please note that this baseplate is not compatible with Roadmaster’s direct-connect style tow bars, which do not require a crossbar assembly. For those systems, a different baseplate kit would be necessary.
For detailed installation instructions and compatibility verification, refer to the manufacturer’s guidelines or consult with a professional installer.

Types of Baseplates
There are two main baseplate styles for most flat towable vehicles:
Direct-Connect: This style lets you attach the tow bar directly to the baseplate—no crossbar needed. It’s the easiest option for quick hookup and disconnect. Ideal for motorhome-mounted tow bars. Note: If you’re using a Stowmaster, Tracker, Guardian Rock Shield, or Tow Defender #4700, choose the Crossbar-Style.
Crossbar-Style: Designed for use with Roadmaster tow bars and accessories that require a crossbar or quick-disconnect system. This is the required option for car-mounted tow bars.
