About X-treme Hummer Performance
X-treme Hummer Performance Specializes in High Performance Duramax Powered Hummer H1's and HMMWV's. Our Duramax Conversions are based on 15 plus years of Duramax performance experience and focus on optimizing the power and efficiency of the Duramax/Allison drivetrain. Our Hummer conversions outperform others and incoporate features that no other company can offer. Our in-house engineering and design staff produce components that no one else offers.
The H1 and HMMWV vehicles are very capable off-road vehicles but are very under-powered and although the Duramax Conversion is the ideal solution for more power, many of the components of these vehicles were not designed to accommodate the significant increase in power and speed that the Duramax conversion offers. We have developed solutions for all of these shortcomings, from Big Brake kits and Custom Coilover suspensions, to Massive Intercooler and Radiator systems. Our Hummers dont just advertise performance, they produce it!
Whether you just want to improve your current H1 Hummer's ride and handling or turn it into a 1000hp Twin Turbo Monster, we can engineer the solutions you need!
