The Patented Gen3 Off-Road Research Damper Interface Device (DID) allows you to install the passive damper system of your choice on your 2021+ Ford Raptor, Bronco Raptor, or Ranger Raptor vehicles and eliminates the Terrain Management system fault warnings that occur when you disconnect the OE semi-active dampers. The DID allows you to maintain your drive modes (Normal, Sport, Baja, Mud, Sand, Snow) which are integral to the vehicle's powertrain and chassis systems.
