Sometimes, to truly appreciate how far something has come, we need to look at where it started. Such is the case for the GMC Hummer — one of the most well-known road warriors in existence.
While neither of the two Hummer H1s are stock, they still embody what the Hummer is at its core: one tough machine.
An excellent example is this 2003 Hummer H1 custom built by Predator in 2016. Predator is one of the largest manufacturers of custom Hummer H1 accessories and specializes in turning stock Hummers into weapons on wheels that can take on anything thrown at them.
Predator gave this Hummer H1 its Duramax conversion, including a 6.6-liter Duramax diesel engine equipped with a Duramax-654 Garrett GT37 AVNT turbo kit. The custom RaptorQ computer tune helps push its power output to 450 horsepower and 900 ft/lbs of trailblazing torque.
Upgrades to the engine include a Duramax-664 Mahle GM piston kit and Duramax-66 IS 30% over injectors. The engine is kept cool by a Duramax cooling package, performance aluminum intercooler and radiator. Other components include a Mean Green high output alternator, race manifolds with up-pipes, custom upper and lower Duramax gasket kit and an OPTIMA YELLOWTOP battery.
The engine is backed by a stage four Allison automatic 6-speed transmission with a 2/4s transfer case and triple-disc converter. A custom-built Predator 6-piston big brake kit provides the stopping power.
Predator gave this H1 a 2-inch lift kit and a radius rod assembly suspension that allows it to make its own roads. When traversing flooded areas with high water lines, the short Gloss-Black snorkel will be helpful.
The Hummer gets its menacing look from its stealth color combination of Corris Grey and black with an exterior steel skin. A Gloss Black D-Ring II brush guard protects the upgraded LED headlights and grille-mounted light bar. Combined with the roof rack-mounted light bar, nothing stays hidden in the dark.
Inside, the driver can monitor the Hummer’s vitals with a high-performance cluster gauge set tucked behind a Momo steering wheel. Other interior amenities include four black vinyl seats, tinted windows, a Yaesu transmitter radio, an aftermarket Clarion Bluetooth radio and a flat-screen TV mounted in the middle dash.
Included with the sale is a matching trailer created from a steel frame and matching exterior steel skin that serves as the ultimate off-the-grid sleeping setup.
The trailer features steel cabinetry, slide windows, carpet and a flat-screen TV mounted to a swivel rack. Anyone can live off-the-grid for weeks with its 12-volt battery, inverter, gas and propane mounts, 20-gallon water tank and pump hookup to the shower and plumbing system.
Another unique offering during the 2022 Houston Auction is a 2006 Hummer H1 wagon with the Alpha package. General Motors only built 729 H1 Alpha Hummers — of those, only 417 were wagons.
The H1 Alpha wagon is powered by the factory Duramax 6600 6.6-liter V8 32-valve turbo diesel engine. It’s capable of producing 300 horsepower and 520 ft/lbs of torque. An Allison 1000 5-speed automatic transmission backs the engine.
This Alpha retains the Hummer ethos with its 16-inches of ground clearance and aggressive approach to departure angles, enabling it to climb 22-inch obstacles and handle a 60% grade. As if that isn’t enough off-road capability, the wagon can wade through 30-inches of water.
This off-road machine is complete with a set of HELLA HID fog lights and a bumper-integrated winch with a brush guard. The vehicle also comes equipped with a Hummer Adventure package and takes it up a notch with the Military FLIR night vision camera system.
From inside the cabin, the driver can control the winch and the fog lights or view what the rearview camera sees with the Alpine touchscreen stereo system, hooked to a Monsoon 5-speaker system including a subwoofer.
Other interior amenities include custom made-to-fit Vizualogic rear headrest tablet LCD screens with WIFI connection.
This Alpha is finished with Metal Grey paint on the body, topped with a black roof for a rugged two-tone paint combination. It rides on Dick Cepek electronically adjustable shocks and the original 17-inch forged aluminum wheels with factory Central Tire Inflation System (CTIS) wrapped in new 37-inch Kanati Mud Hog M/T tires.
According to the consignor, all the work and service have been done by professional Hummer-certified technicians.
The sale includes original books and manuals, the mini rescue kit and service receipts.
Both of these H1s are offered with No Reserve at the 2022 Houston Auction — each just waiting for adventure.
