text: GM Hummer - 2009 Hummer H3T - Chassis
  The H3T's frame and suspension system are based on a stretched version of the H3 SUV's chassis and suspension – the same race-proven design found on Baja 1000-winning stock-class race trucks. The wheelbase measures 134.2 inches (3,409 mm) – 22 inches (86 mm) longer than the H3 SUV. A ladder-type frame is the truck's foundation and it has a modular, three-piece design that incorporates fully boxed components for outstanding strength and stiffness. An independent SLA torsion bar front suspension and multileaf Hotchkiss-type rear suspension are used. There are two suspension packages available:
  Ability to climb a 60-percent grade and traverse a 40-percent side slopeExceptional 10.2-inch (285 mm) ground clearance (with 33-inch tires)38.7-degree approach angle and 30.1-degree departure angle (with 33-inch tires)Segment-first available front- and rear-locking differentials
  "For most lifestyles, there's almost nothing the H3T can't handle," said Walsh. "It's a truck with HUMMER's immutable capability."Complementing the features that enable the H3T's impressive off-road prowess is a host of first-class protective elements, including four standard skid shields: a front shield, an oil-pan shield/front-axle shield, a transfer case shield and a fuel tank shield.
