This truck is 4x4. There is no selection for this feature. It has 33" brand new tires on it with great 17" rims. I put in MSD coil packs, a cold air intake, throttle body spacer, 2 chamber flow master exhaust and strut over shock rear suspension. It also has a 2.5" leveling kit in the front. And 1.5" wheel spacers installed. The front shocks are fairly new. The crankshaft position sensor is brand new. I put in the egr valve new too. It needs the vavle cover gaskets changed which i have but never put in. I also have new exhast tips. And the cv axle on passanger side needs to be replaced but it a $76.00 part. Please let me know if your interested.
