Hummer is one of the most recognizable names out there. The mere mention of the name conjures of thoughts of unmatched off road performance. In these times of high gas prices it also makes you think of a big hit to the wallet with every fill up. Well guess what!!  We've found a conversion kit for hummer that can increase overall performance of the H1 and H2 while increasing fuel economy to 22 MPG. That's right!!! 22 MPG from one of the nastiest offroad vehices out there. It's a Duramax conversion kit. It's supplied by Predator motorsports but they don't sell to the general public. So Elite Aftermarket is the place to get your hands on this money saver.  The conversion consists of removing the stock engine, transmission and transfer case and replacing with the Duramax Engine, Allison Heavy Duty 5-speed Transmission and selectable 2WD/4WD transfer case. This conversion enables you to operate a selectable 2wd/4wd system which increases fuel economy up to whopping 22 mpg. Not sure of the price tag on this baby but with gas prices continuing to move upward the price may just be right.
