This custom 2001 Hummer H1 is powered by a GM turbo-diesel V8 engine paired with a 4-speed automatic transmission and enhanced with Predator performance upgrades that include a tuned exhaust, intake, injection system and ECU calibration.

Additional factory updates for the 2001 model year include improved induction components, a revised electrical system and a reengineered fuel supply and filtration system, increasing total onboard capacity to 51.5 gallons.

Exhaust performance is improved through the Predator-tuned system, which works in conjunction with the updated induction and fuel-delivery components.

The chassis incorporates the model-year upgrades introduced by GM, including a high-strength steel structure, a reinforced steering gear, quieter axle differentials with helical gears, and improvements to key electrical and support systems.

This H1 maintains 16 inches of ground clearance and is capable of climbing a 22-inch obstacle, handling a 60% grade and fording up to 30 inches...
