2009 Automatic Gasoline mileage: 1 KM 4WD Hummer H3 Alpha, 6-liter engine, 400 horsepower, front and rear diff lock. The modifications done to it: (The previous engine was 5.3 V8, I replaced it with a 6.0-liter engine with the same original wiring and harness. For over 3 years, only the rear-wheel drive has been used, and all differentials and diff locks are working. Lower fuel consumption and better performance). Please contact via WhatsApp: 0541911995. The car has undergone a full maintenance and is ready for use. There are no oil leaks or any issues.
