Roadmaster Crossbar-Style Baseplate Kit with Factory Steel Bumper/Winch – 2024 Jeep Wrangler

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.

• Smart design – Integrates into the frame using existing holes for faster, cleaner installs

• Strength-tested – Computer-simulated testing ensures maximum durability
• Custom fit – Tailored to each specific year, make, and model
• Wide compatibility – Over 1,000 baseplate options for most towable vehicles from the past 25 years

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.
