Features to know about

Built for Heavy-Duty Towing: Fixed-Bar, All-Steel Design

When reliability matters most, this setup delivers. The Roadmaster Direct-Connect Base Plate Kit features a fixed-bar design with front arms that stay in place for consistent strength. Each bracket is computer-cut from all-steel construction to provide exceptional durability and a solid connection point for your motor-home-mounted tow bar. It’s built to handle heavy-duty applications with confidence mile after mile.

Simplify the Setup: No Crossbar Needed for Hookup

This base plate eliminates the need for a crossbar, so connecting your tow bar is faster and cleaner. The direct-connect design pairs directly with Roadmaster tow bars that slide into a trailer hitch receiver—models like the Nighthawk, Sterling, Blackhawk, Blackhawk 2, Falcon, and Falcon 2. Without the extra crossbar hardware, you get a sleeker appearance up front and fewer steps each time you hook up.

Tough Finish That Lasts: Black Powder Coat Protection

The black powder coat finish adds more than just looks—it’s durable and corrosion resistant. Whether you’re towing through rain or road grit, this finish helps shield the steel frame from rust and wear so your setup stays dependable over time. It’s a design that takes hard use and keeps performing.

DIY-Friendly Install: Custom Fit and Straightforward Mounting

You don’t need to weld anything to get this base plate in place. It’s custom-cut to ensure a precise fit on your vehicle’s frame, which makes installation simpler and alignment easier. The kit includes instructions and mounting hardware so you can bolt it up with basic tools and get back on the road with a secure connection for your tow bar setup.

Specs

Construction and Design

  • Design: Fixed-bar design - front arms cannot be removed
  • Construction: Computer-cut, all-steel construction provides exceptional strength
  • Finish: Black powder coat finish is durable and corrosion resistant
  • Installation: Simple installation - no welding
  • Fit: Custom base plates ensure a perfect fit for your vehicle
  • Crossbar Requirement: No crossbar needed - faster hookup and sleeker appearance
  • Compatibility: Compatible with all Roadmaster tow bars that slide into trailer hitch receivers
  • Included Components: Instructions and mounting hardware included
  • Origin: Made in the USA
  • Warranty: Limited Lifetime Warranty

Note

  • Note: Direct-connect base plates will work only with the Roadmaster tow bars that slide into a trailer hitch, such as the Nighthawk, Sterling, Blackhawk, Blackhawk 2, Falcon, and Falcon 2. These plates will not work with tow bars that require a hitch ball.
  • Direct-connect brackets do not require a crossbar because of the heavy-duty nature of your vehicle's frame. Thus, installation is simplified, the hookup process is faster, and the total appearance is enhanced.
  • Note: The EZ Hook safety cables included with Roadmaster's Sterling tow bars will not work with these base plates. These cables connect to an anchor plate on the Quick Disconnect crossbar, which will not be present when you are using direct-connect base plates.

See what our Experts say about this Roadmaster Tow Bar Base Plate

  • Comparing Roadmaster Base Plates for 2007 Hummer H2 and Recommended Flat Towing System Components
    The Roadmaster MS Base Plate Kit - Fixed Arms # 2503-1 does not have the removable connections like the # 2506-1 or even the # 2506-3. The removable option gives you a cleaner look when not connected, but the connection will be similar. The # 2506-1 style of arms is compatible with Quick Disconnects and all Roadmaster tow bars, where the other options are not able to use the Quick Disconnects and are not compatible with coupler style tow bars. This compatibility is the only reason why...
