Chevy HDDetroit, Michigan - The Chevy Silverado H.D. Pickup begins its first full year of production in 2002, and continues to build momentum after its introduction last year as the segment’s most powerful line of all-new three-quarter and one-ton pickups and chassis cabs.

Comprehensive lineup

Chevrolet Silverado offers a selection of 32 heavy-duty models, including 2500HD (3/4-ton) and 3500 Series (one-ton) regular cabs; four-door extended cabs, Crew Cabs and chassis cabs. Four special versions of the heavy-duty pickups, with a reduced gross vehicle weight rating (GVWR), are available for alternative fuel vehicle customers.

Most powerful engine lineup

The segment’s most powerful gasoline and diesel engines drive the 2500HD/3500 Series to the head of its class in performance. The new powertrains were validated for an extended operating life of at least 200,000 miles (322,000 km).

Duramax 6600 V8 tops diesel class

The Duramax 6600 diesel V8 is a state-of-the-art, 90-degree, direct-injection, overhead valve, four-valve-per cylinder, turbocharged and intercooled V8, developed through a joint venture between GM and Isuzu Motors. From virtually any perspective, the optional new Duramax 6600 provides more customer benefits than competing diesels.

Highlights include:

  • More power. With 300 hp at 3100 rpm and 520 lb-ft (705 Nm) of torque at 1800 rpm, the Duramax 6600 produces 65-70 more horsepower and 20-70 lb-ft more torque than the competition’s diesels.
  • Segment-leading acceleration at any load level. Acceleration tests show that the heavier the load it pulls, the more quickly the Duramax 6600 outdistances its competitors.

Chevy HDVortec 8100 big block V8 tops competitors’ V10s

An optional Vortec 8100 V8 gas engine is built on one of the most celebrated engine foundations in automotive history, GM’s Big Block V8. With 340 horsepower at 4200 rpm and 455 lb-ft (617 Nm) of torque at 3200 rpm, the Vortec 8100 produces 40-65 more horsepower and 30-45 lb-ft more torque than Ford and Dodge V10 engines.

The Vortec 8100 also provides best-in-class gas engine acceleration.

Most powerful standard Vortec 6000

The Vortec 6000 V8 is the most powerful standard engine in its class, with 300 hp at 4400 rpm and 370 lb-ft (501 Nm) of torque at 4000 rpm. It produces 40-50 more horsepower and 25-35 more lb-ft of torque than the competition’s largest gasoline V8s.

Smooth-shifting, high capacity transmissions

The Duramax 6600 and Vortec 8100 mate to smooth shifting, high capacity transmissions, including a standard ZF S6-650 six-speed manual and optional Allison 1000 five-speed automatic. Both have close-ratio gearing, which provides exceptional launch, hill climbing and towing capability and economy. Their heavy-duty components are stronger than those typically found in one-ton truck transmissions, providing exceptional durability.

The ZF S6-650 six-speed is fully synchronized in all gears for easy shifting. Dual cone synchronizers in second and third gear provide extra capacity. High helix angle gears provide quiet operation. A convenient shift pattern allows the shift lever to be moved forward for reverse and straight back for first, providing easy low speed maneuvering. Second can be used for launching unloaded or lightly loaded trucks. First gear can be used as a "creeper gear" for extra low-end performance.

The Allison 1000 is a GM-exclusive. It has full electronic control of shift timing points, five forward speeds, and helical-type planetary gearsets for quiet operation. It also provides two operating modes, normal and Tow/Haul. In the latter, the torque converter clutch engages in second, third, fourth and fifth gears to avoid excessive heat buildup when the truck is heavily loaded.

Heavy-duty five-manual and GM’s optional 4L80-E four-speed electronically controlled automatic transmissions are available for the Vortec 6000. The 4L80-E also provides the benefits of Passive Shift Stabilization with its Tow/Haul mode, two year/50,000-mile (80,000 km) transmission oil change intervals and a standard temperature gauge and temperature monitoring system.

Chevy HDTop hauling, trailering capability

With awesome power, tough frames, advanced suspensions and higher capacity brakes, the 2500HD/3500 Series provide outstanding payload capacities and unparalleled hauling and trailering capabilities, including:

  • The 3/4-ton segment’s highest 9200-pound (4173 kg) GVWR (400 pounds/181 kg more than competitors) and payloads of up to 3964 pounds (1798 kg)
  • The one-ton pickup segment’s highest 11,400-pound (5171-kg) GVWR and payloads of up to 5753 pounds (2610 kg)
  • An 11,400-pound (5171 kg) GVWR for 2WD chassis cabs and 12,000-pound (5443 kg) GVWR for 4WD chassis cabs. Chassis cabs provide payloads of up to 6089 pounds (2762 kg).

Both the Vortec 8100 and Duramax 6600 Diesel V8 permit towing trailers up to 12,000 pounds (5443 kg); they provide a maximum 22,000-pound (9979-kg) gross combined weight rating (GCWR).

With a fifth wheel or gooseneck hitch, trailering capability increases to an astounding 15,800-pound (6804-kg) maximum. The Vortec 8100 provides its maximum ratings with either a 4.10:1 or 3.73:1 axle ratio; the Duramax 6600 offers a 3.73 axle ratio.

With a weight-distributing platform hitch and 4.10 axle ratio, the Vortec 6000 V8 permits towing trailers weighting to 10,500 pounds (4763 kg) and provides a maximum 16,000-pound (7257-kg) GCWR.

The heavy-duty pickups are trailer ready. A Handling and Trailering package is standard. A Trailering Equipment package provides the weight-distributing hitch platform, eight-wire trailer harness with mounted connector and a jumper harness with a plug-in for the electric trailer brake controller.

Suspension, braking and steering systems

A long- and short-arm independent front torsion bar suspension is standard on all models.

Semi-elliptic multi-leaf rear springs operate in two stages on pickups and in three stages on one-ton chassis cabs. A world-class four-wheel disc brake system, featuring GM’s powerful Hydro-Boost brake apply system and four-wheel ABS, is standard all models.

Wheels and tires

Wide standard 16 x 6.5-inch eight-bolt steel wheels provide great stability, and 2500HD/3500 Series also have E-load range tires to help provide for increased load-carrying capability. The 2500HD models feature standard LT245/75R16E radials with either an all-season or on-/off-road design, depending on the model. The 3500 Series have standard LT215/85R16-E highway or on-/off- road radials. A full-size spare is standard.

Cabs, safety and security

Regular, four-door, extended and Crew Cab sizes have significant interior room and outstanding seating comfort. The extended cab has the industry’s largest rear-door openings. The Crew Cab has even more headroom, leg room and hip room than the segment-leading Extended Cab.

The 2500HD/3500 Series has the OnStar system. It is now standard on uplevel Silverado LT extended cab and Crew Cab models. OnStar adds safety and security features such as automatic air bag deployment notification and emergency assistance with remote location.

All models have standard dual air bags, with a passenger side deactivation switch on regular and extended cab models to protect small occupants.

With several best-in-class advantages, Silverado H.D. stands ready to increase Chevy’s heavy-duty pickup market share in 2002.
