2008 HUMMER H2 SUV

2008 Hummer H2 Duramax Diesel Conversion Allison 6-Speed 2WD/4WD Selectable This is not your average H2. This is a professionally executed, same-year diesel conversion that transforms the driving experience of the H2 into something far more capable, efficient, and desirable. Originally built as a gasoline-powered SUV, this 2008 Hummer H2 has been converted using a correct-generation LMM Duramax diesel drivetrain paired to a 6-speed Allison automatic transmission and matching transfer casea combination never offered by the factory in the H2 platform. What makes this build truly stand out is the approach: Rather than mixing mismatched components from different eras, this conversion utilizes a same-year drivetrain integration, allowing for far better compatibility, drivability, and reliability compared to typical diesel swaps. Performance & Drivetrain LMM Duramax 6.6L Turbo Diesel Allison 6-Speed Automatic Transmission (upgrade over earlier 5-speed units) Selectable 2WD / 4WD Transfer Case (unlike factory full-time AWD) Factory-rated at 365 HP / 660 lb-ft torque Equipped with a tuning switch for increased power and torque on demand This setup completely transforms the H2. The added torque delivers effortless acceleration, improved towing capability, and a driving experience that feels far more modern and responsive than the original gasoline configuration. The addition of 2WD mode also allows for improved fuel efficiencysomething the factory full-time AWD system never offered. Chassis & Condition 109,000 miles on chassis New shocks all around Ice-cold A/C Smooth, easy drivabilitycomfortable around town or on the freeway Wheels & Tires Brand new Raceline 20x9 959MC wheels Brand new 35x12.50R20 Nitto Ridge Grappler tires Matching full-size spare (no shortcuts taken) Additional Notes Roof rack removed for garage clearance (included with sale) Clean Montana title in company name Turn-key and ready to go Important Will not pass California emissions Summary This H2 represents what the platform should have been from the factorya torque-heavy, diesel-powered SUV with a proper transmission and selectable drivetrain. Between the LMM Duramax, Allison 6-speed, and thoughtful execution of the conversion, this is a rare opportunity to own a uniquely capable H2 that stands far apart from anything else on the market.
