Overview:
The Chevy Silverado HD 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.
This
guide covers the heavy-duty versions of the Silverado, which come
in 2500 (three-quarter ton) and 3500 (one-ton) series. The light-duty
versions of the Silverado are covered separately in the Silverado
guide.
Chevrolet
offers a selection of 32 heavy-duty models, including 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.
The
2002 Silverado HD is offered in the following configurations and
trim levels:
2500
HD, 3500 Reg. Cab, fleetside, long box-standard and LS
2500 HD Ext. Cab, fleetside, short box-standard LS and LT
2500 HD, 3500 Ext. Cab, fleetside, long box-standard, LS and LT
Crew Cab, fleetside, short box-standard, LS and LT
Crew Cab, fleetside, long box-standard, LS and LT
The
Silverado HD is all about power and capability and for 2002 there
is plenty to go around.
In
this segment the engine counts most. Three class leading engines
are available.
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.
The Vortec 8100 gasoline V8, with 340 horsepower at 4200 rpm and
455 lb-ft of torque at 3200 rpm, 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.
Finally,
the Silverado's standard engine, the Vortec 6000 gasoline V8, is
the most powerful standard engine in its class.
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 GVWR (400 pounds more
than competitors) and payloads of up to 3964 pounds
The
one-ton pickup segment’s highest 11,400-pound GVWR and payloads
of up to 5753 pounds
An
11,400-pound GVWR for 2WD chassis cabs and 12,000-pound GVWR for
4WD chassis cabs. Chassis cabs provide payloads of up to 6089 pounds.
Both
the Vortec 8100 and Duramax 6600 Diesel V8 permit towing trailers
up to 12,000 pounds; they provide a maximum 22,000-pound gross combined
weight rating (GCWR).
With
a fifth wheel or gooseneck hitch, trailering capability increases
to an astounding 15,800-pound 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 and provides
a maximum 16,000-pound 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.
Exterior
Design:
There are no exterior changes for 2002.
Interior
Design:
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 live operators.
All
models have standard dual air bags, with a passenger side deactivation
switch on regular and extended cab models to protect small occupants
Powertrain:
To meet California’s Low Emission Vehicle requirements, refinements
have been made to Silverado’s Vortec 6000 V8 engine.
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.
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 transmission oil change
intervals and a standard temperature gauge and temperature monitoring
system.
