Details

Originally designed for military use, the AM General Humvee was released to the civilian market due to popular demand as the H1. For the 2006 model year, GM released the upgraded Hummer H1 Alpha, equipped with GM's 6.6-liter Duramax turbo-diesel V8 engine backed by a 5-speed Allison 1000 automatic transmission. Horsepower was up 46% over the previous H1s, and peak torque was increased 18% over the standard H1. Beyond the GM Alpha upgrades, the most recent owner strived to upgrade this H1 Alpha with the help of Predator, Inc., and Canepa. Treated to a full workup of Predator's performance accessories, this Hummer features a Predator-tuned exhaust, Predator intake with a hood scoop, Predator injection and ECU management to produce 360hp and 640 ft/lbs of torque. The additional Predator accessories include the Trek-R steering kit, roof rack, brush guard and an LED lighting package. Some major modifications from the previous H1s included the use of special high-strength steel in the chassis frame, a more powerful steering gear, quieter axle differentials, redesign of the geared hubs to use quieter helical gears, new induction, exhaust and electrical power systems, and reengineering of the fuel supply and filtration system. A revised fuel system also increases the capacity of the Alpha H1's two onboard tanks to 51.5 gallons, 9.5 gallons more than previous H1s. To accommodate the new dimensions of the Duramax 6600 and Allison 1000, the body of the H1 Alpha is positioned 2 inches higher than the previous H1. This provides slightly more clearance for the body panels from the wheels and from potential obstacles on trails. Now boasting 16 inches of ground clearance, as well an aggressive approach and departure angles (72/37.5 degrees), the H1 could climb a 22-inch-high obstacle, handle a 60-percent grade, and wade through up to 30 inches of water. It accomplishes this rolling on 18-inch GT/Cepek wheels, with beadlocks and Central Tire Inflation System tire pressure control, all wrapped in Toyo Open Country M/T tires. It also features larger brake rotors, going from 10.7 inches to 12 inches in diameter. This Alpha also features a custom black-leather interior with sound-deadening throughout, a custom Alcantara headliner, tinted windows, a Momo steering wheel and an upgraded audio system. Originally acquired from Hummer of Cincinnati, this H1 received vehicle inspections and service since new. Given the factory odometer was replaced with a total mileage of 81,646 miles, the odometer reads 40,173 miles (title reads exempt). CARFAX shows potential odometer rollback on 12/21/2016; Damage report on 06/24/2022: Accident reported, vehicle involved in a sideswipe collision, airbags did not deploy.
