The jeep has the inline six motor with shaved head and bigger cam, lifford intake,MSD ignition system, barrel holley, ong tube split headers. Runs like a sewing machine and is fast. I have installed new front and rear bumpers with a 9500 lb warn winch and a full size 35 inch tire on rear with a high lift jack. I have been working on this jeep since 2003 The only thing that hasnt been changed are the rear ends. It is for sale locally please text with any questions 803-600-6743 my name is Joey. This jeep has over 25k invested in it and has been my baby for years but sadly I dont have that much time to ride it any more
