2wd 5 spd 3.0l. has jet performance programmer. k and n air filter and a flow through muffler for some added performance. too much new to list. I'll list instead what I haven't done. clutch and starter. and I have both to go with the truck. is my daily driver. runs and drives great. mechanically speaking this truck should go another 500000 km. looking to trade for any kind of 4x4.
