Construction
The GRAV earth point consists of a profile connected to the aluminum front end with a threaded stud. An earth lead is connected to this threaded stud. The earth lead goes to the steel body.
How it works
The connection of the lightweight aluminum front end (GRAV) and the steel body with an earth lead improves the vehicle's electromagnetic compatibility (EMC). Contact resistances between the front end and the rest of the body are bridged.
