Lift kit and tires
I live in Norway and Im building a 1984 Chevy K20 Silverado with 6" suspension and 3" body lift. I have put on 38x15.5x20 tires.
My problem now is to get the truck street legal, I have talked with the norwegian DMV and they need documentations on that the truck are able to handle this amount of lift and the wider track width these tires give me. They need this kind of documentation either from GM, or from a independent laboratory, like TUV in Germany.
So my main quiestion is, does anybody know if GM will give me papers that say that my truck will handle these modifications? And how do I get in contact with them?
