1984 pickup had a bold new bi-level grille. Two galvanized steel interior
door panels were a new rust-fighting feature. Also new were semi-metallic
front brake linings on C/K10 and C/K20s. Non-asbestos rear brake linings
were used on most models. The U.S. Army purchased nearly 30,000 full-size
Chevrolet 4x4 pickups with 6.2-liter diesel V-8s. The trucks were
said to be "like the ones you can get, except for a few specialized
Chevys had another front end redesign. A new custom two-tone body-color
treatment was seen. It had a sportier look with a tapering color panel
on the cab and fender sides. GM's Vortec six was standard. A
real "Country Cadillac" was the "Big Dooley" with
flared rear fenders and dual rear wheels.
1985 light-duty truck sold by a U.S. Chevy dealer came with a one-year,
$10,000 seat belt insurance certificate at no additional charge. Under
the policy, $10,000 would go to the estate of any occupant suffering
fatal injuries as a result of an accident involving that vehicle while
wearing a GM seat belt.
kicked off a 75th anniversary celebration in 1986. By year’s
end, the company would make 1,174,217 trucks. New was a high-tech instrument
cluster. The Vortec V6 had electronic fuel-injection and swirl-port
heads for a nine percent power boost. It was Chevy’s most powerful
base truck engine ever.
Chevy’s full-size pickups (the ones called C/K models in 1986) were
R/V models in 1987. New full-size pickups based on the so-called GMT400 platform
were introduced in mid-1987 as the “1988” C/Ks. Throttle
body injection was fitted to all. Engine-mounted mechanical fuel pumps
were replaced by electric units in the gas tank. This, along with a fuel
pressure regulator, provided instant and constant fuel pressure for precise
fuel control during starting and driving.
Vortex V6 remained base engine. It came with lower-friction roller-hydraulic
valve lifters that upped engine efficiency, while providing a three percent
fuel economy increase. Chevrolet also installed new lower-weight Delco
batteries with higher cold-cranking current for all gasoline engines.
Chevrolet C/K Pickups
all-new pickups on April 23, 1987 as 1988 models. The new trucks were
produced at three plants in Fort Wayne, Ind., Pontiac, Mich. and Oshawa,
Ontario, Canada. Adding sales appeal, as well as representing a new
avenue of versatility, were extended-cabs with optional six-passenger
of the new models were 117.5-in. for standard models, 131.5 in. for
long-wheelbase and extended-cab models and 155.5 in. for extended-wheelbase
models with extended cabs. These dimensions were unchanged from 1987,
although the new trucks were longer than the old ones.
was 3.5-in. narrower, but the interior had more leg and shoulder room
and seat travel. The new models had larger doors that extended into
the roof line and down nearly to the bottom of the rocker. These, along
with a low step-up height and high headroom, made for ease of entry
had a box that measured 49.15-in. between the wheel wells and 63.8-in.
between the side panels. Flush side glass, a modular-assembled bonded-flush
windshield, single-piece door frames and robotic welding made the new
trucks very advanced. Hidden roof pillars and built-in drip rails eliminated
matching problems on door cuts. The back of the cab and front of the
box were mounted on a single, one-piece fixture, eliminating mismatch
of the two sections.
A new single-piece
grille eliminated potential molding mismatch. There were single headlamps.
The Silverado was equipped with dual halogen headlamps. Structural
rigidity was improved by double-panel construction on the roof, hood,
fenders, doors and box. Glass area was a third larger. A bonded, angled
and curved backlight cut glare. The windshield wiper sweep was larger.
anti-corrosion protection was a high priority. The all-welded box had
a seamless floor without bolts to fight corrosion. Two-sided galvanized
steel was used for major exterior panels, except the roof. All exterior
sheet metal was primer dipped. Anti-stone protection was used. The
windshield and backlight were made without mitered corners.
bumper had no attaching bolts to improve appearance and eliminate a
source of corrosion. Prior to painting, all sheet metal panels were
immersion-washed to remove contaminants for better paint adhesion. A
uniprime ELPO dip treatment drew the protective primer into recessed
areas. The color coat/clear coat paint gave a hard, high-luster finish.
base trim was Cheyenne, a new value standard in full-size work trucks.
The mid-range Scottsdale was described as, "a big step up in a
sensible blend of function and form." Silverado was the top-of-the
line trim package.
used independent coil spring front suspension in all weight classes.
C1500/C2500s used a semi-floating rear axle and C3500s had a full-floating
one. Four-wheel-drives had a new independent front suspension with
a hypoid driving axle and torsion bars. It utilized a wire-form design
for upper control arms with lighter, stronger parts. The torsion bar
springs and jounce bumpers were connected to the lower control arms.
The torsion bars were computer selected to match a truck’s
GVWR and balance with the rear springs.
4x4 frame had an additional cross member under the transmission. Their
new "Shift-On-The-Fly Instra-Trac" system allowed shifts
from 4x2 to 4x4 high and back, without stopping, at any speed.
The front axle disconnect system locked the front hubs automatically
when a lever operating the 4x4 system was pulled back. The shifter
connected directly to the transfer case. In 4x2 mode, the front-axle
disconnect allowed the front wheels to turn freely. In 4x4 mode,
the transfer case split the power equally to the front and rear wheels.
axles on 4x4s were of the same type and capacity as on 4x2s. The
K1500 had off-road option with a front differential carrier, engine and
transfer case shields, front stabilizer bar, gas shocks and heavier jounce
V6 for K1500-K2500s had a new one-piece rubber oil pan gasket to help
prevent oil leakage. At midyear, Chevy introduced a new K1500 Sportside
model on the 117.5-in. wheelbase. It had a 6.5-foot long pickup box.
The fiberglass rear fenders or side panels were flanked by functional
