I bought a brand new 2007 Chevy Sil 2500HD dirtymax. Couple of questions I have. What truck do I have? I hear all this talk about LBZ LLY ???? I love this truck. I bought it in Feb of this year. I already have 14000 miles on it LOL. Today it said the fuel filter needs to be changed? I'm thinking there must be a reset like there was for the oil. What things should I look for? I want this thing to last. Heres a pic. 6" lift and 35" open countrys.
