I'm seriously considering the purchase of this truck. Anybody know if there are issues with huge GM lift kits? The tires appear to be wearing evenly. Its gets up to 80mph smoothy (2007 Duramax) and the suspension parts look very well designed. I have no idea what brand, height, articulation, etc. I'm familiar with Jeep lift kits but this is a different animal. Any advice would be appreciated.
