I have a 2004 GMC Sierra 1500 are. Cab 4 wheel drive. It's not a high in the air model from the manufacturer. Maybe just a shy higher than a reg truck. I think it has 16 inch wheels so it sits lower than you would think it would. It's not like a Z71 or any similar variant. If I wanted to do a 2 or 3 inch drop what all would be involved in that. I installed a 2 inch drop kit on my Trans AM with Bilstein's. So I know what involved in a car but I am clueless on a truck. I don't go off roading, 4×4 would only be used in snow up here so no probs there. What am I looking at parts wise for lets say a 2 inch in the front and 3 to 4 in the back. Any suggestions would be greatly appreciated.
