About Us

OUR MISSION

X-treme Hummer Performance focuses on optimizing the performance of the H1 Hummer and Military HMMWV. These vehicles have world renown off-road capability, but significantly lack the performance needed to keep up with today's technology. Through 15 years of experience with the Duramax/Allison drivetrain we have created 600+ hp Hummers and quickly identified the weak points in the driveline, suspension and braking systems.

Using the latest Engineering tools and equipment we Design, Engineer and Fabricate custom components that enable the H1 and HMMWV to perform on a level that compete with today's high performance offroad vehicles. Using the best components and hardware keep our products on par with the Level of quality and performance expected of a Luxury Offroad vehicle.
