H3 Alpha trail truck offroad test. We found an increasingly rare H3 Hummer Alpha on craigslist as our next project truck. We made a few quick and easy offroad upgrades to get it to a trustable overland 4wd. New BFGoodrich 35 KM2 Mud terrains. ATX wheels black satin. New rear leaf spring shackles. New KC hi lights LEDs. Warn winch. Custom Warn winch bumper mount. SuperChips 91 octane performance tune for the GM 5.3L V8. JBA CA emmissions shorty headers. Magnaflow dual mufflers. True dual exhaust front to back with X pipe. Then the big project was a complete cleaning, wire brushing and painting the entire chassis and drive train. It lived in Illinois for its whole life so there was rust. Luckily it was all surface rust and no body rust cancer holes.
