Here I have a 2001 Silverado 2500 4x4 duramax equipped with the 6.6 motor and Alison automatic tranny also know as the LB7. Has fab tech suspension aftermarket air filter Fass fuel system and it is straight piped. 20 inch aftermarket rims wrapped in 35 nittos basically new! Clean Colorado title heater and ac work good, along with heated seats. Comes with fuel tank ready to work and a low profile tool box. Willing to trade for a car let me know what you got prefer a charger RT but willing to entertain offers!
