This thing is a BEAST! It has a 5. 7 liter GM Goodwrench gas engine that will GET UP AND GO. I have replaced many of exterior parts including: headlights. tal lights. turn signals. grille. and side mirrors. On the inside I have replaced the stereo system and Rhino lined the entire interior and exterior. It has a 4" Rough Country suspension lift with American Racing wheels and 37/14. 5R15 Toyo Mudders. The motor starts up first time. every time. The transmission shifts smooth. with the exception of when it downshifts out of overdrive into 3rd gear. it's a little harder but thats a typical trait on those older transmissions. The only leak it has is one of the seals on the transfer case.
