The Roadmaster Direct-Connect Baseplate Kit for 2003-2007 GM Heavy Duty trucks and SUVs delivers a custom-fit towing system that is made from weather-resistant steel. The baseplate installs quickly and securely mounts to the vehicle frame. The hidden bracket design keeps the front of your vehicle clean and low profile. Compatible with motorhome-mounted tow bars. Note: Roadmaster direct-connect baseplates will only work with Roadmaster tow bars that slide into a trailer hitch, such as the Blackhawk, Blackhawk 2, Falcon, or Falcon 2. These baseplates will not work with tow bars that require a hitch ball. Fitment• 2003-2006 Chevrolet Silverado 1500 Pick-Up 1500 HD, 2500, 3500.
