| Wheelbase | longer than a Chevy Tahoe, while its overall 189.8-inch body length |
| is 9 inches shorter. On-road, the long wheelbase helps smooth out |
| the ride; off-road, it helps prevent pitching in rough terrain. |
| Approach and | Extremely short overhangs, including a 32.6-inch front overhang |
| Departure Angles | and 34.6-inch rear overhang. The short overhangs provide high |
| | approach and departure angles, allowing the H2 to drive right into a |
| | hole and out again without getting hung up in front or rear. These |
| | approach and departure angles are the highest of any GM fullsize truck. |
| Modular Frame | A fully welded ladder-type frame with a modular, three-piece design |
| that incorporates a number of hydroformed (formed with water |
| under high pressure, which allows steel to retain more of its |
| strength through the manufacturing process) components, for |
| outstanding strength, stiffness, and dimensional accuracy. |
| Belly Protection | Rock-defying underbody protection, which helps define H2's |
| uniquely rugged character and enhance its performance |
| characteristics. It includes large, thick skidplates; an undershield |
| for the fuel tank; totally unique, chassis-bolted steel rocker panel |
| protectors; a protective shield for the optional on-board air |
| compressor, and mud flares that run up, around, and over wheels. |
| IFS/Five | An independent front torsion bar and five-link coil-spring or |
| Link Rear | airbag rear suspension, providing excellent on-road ride comfort |
| and control and a high degree of strength, control, and rear-axle |
| articulation off-road. Its solid rear axle provides durable sure- |
| footedness, particularly in tight off-road situations. |
| Air Spring Options | A new optional self-leveling rear air spring suspension system |
| | tuned to H2's severe off-road requirements included in the off- |
| | road suspension package. |
| Adjustable Seats | Comfortable seats with standard eight-way power adjustment for |
| the front seat cushions and backs, and a standard memory |
| feature for the driver's seat that allows two drivers to select and |
| set their preferred positions, using key fob buttons or controls in |
