2003 chevy Tahoe With HD hood , Truck has about 1 year and a half since transmission was rebuilt also aftermarket transmission cooler was installed , few other parts replaced were :     •    Alternator     •    Oil pick up tube and O ring     •    Intake gasket     •    Knock sensor and harness     •    Water pump     •    Radiator     •    Spark plugs and wires     •    Lower ball joints     •    Upper control arms     •    2 inch drop spindles with drop              keys     •    Rear has 4 inch drop springs     •    New belltech drop springs     •    Has cold air intake I also have new oil pressure sensor from AC deleco with valve cover gaskets included with the truck to be installed Smog ready Has new o2 sensor Cons : the tire it sits on is to big for the drop so it is rubbing , suspension needs to be adjusted to what ever wheel installed , the rear is bottoming out so youd have to cut the bump stop brackets for more travel
