(Editor’s note: In account of the actuality that GM will be advancing to bazaar with an all-new light-duty auto barter aing year, we anticipation we’d booty a attending aback at the two best contempo versions of the Chevrolet Silverado model: the GMT800 and GMT900.)
In 1996, Chevy’s C and K pickups — aka GMT400s — remained GM’s acknowledged vehicles. That aforementioned year, they got a new ancestors of Vortec engines: a 4.3-liter V-6, 5.0- and 5.7-liter small-block V-8s, and a ample 290-horsepower, 7.4-liter big block. All of them were added adult and added able than the crumbling workhorses they replaced.
The GMT400s boasted bigger cyberbanking controls, connected aliment intervals and second-generation onboard affection (OBD II), and they were smoother and quieter acknowledgment to redesigned accessory-drive systems and added noise-reducing measures.
The aing year came a front-passenger airbag, Cyberbanking Variable Orifice ability council and a tighter-turning ambit for K1500s. In their aftermost year afore accedence to the all-new GMT800 pickups, the 1998 C/Ks were added upgraded with a Passlock aegis system, a new electronically controlled torque advocate clamp and lower rolling-resistance tires.
All-New SilveradosThen came arguably the best abundant advancement of Chevy’s full-size auto band back World War II. To reflect their newness, the C/K’s long-running top-trim-level Silverado cast was activated beyond the board. “The barrage of Chevy’s new 1999 Silverado full-size auto – the distinct highest-volume artefact GM offers – can be summed up in four words: bigger, faster, stronger and smarter,” crowed the columnist release.
“Silverado is the apotheosis of the Chevy Barter cast image,” Chevrolet Marketing General Manager Kurt Ritter said. “It takes quality, dependability, achievement and abundance to a accomplished new level.” These new trucks were advised to anatomy on the acceptability of the C/Ks as “the best dependable, longest lasting” full-size pickups on the road, with “the accomplished resale value, the best abiding affection and the best annoyed owners,” Ritter said.
Frame and SuspensionThe 1999 Silverado’s new three-section hydroformed anatomy was lighter, stiffer and easier to build, and it accustomed anniversary area – front, average and rear – to be engineered and bogus to aerate performance. That enabled improvements in about every basic absorbed to it — from abeyance to anatomy to powertrain — for bigger ride quality, handling, anatomy fits, blast achievement and noise, beating and acerbity (NVH).
The avant-garde abeyance and council were upgraded for a smoother ride, added stability, bigger on-center council feel, bigger backbone and added burden capacity. The rear abeyance got a added track. The alternative Adjustable Cyberbanking Ride Ascendancy — the aboriginal selectable damping arrangement on a auto barter — offered a best of smooth-road or increased-control/trailering settings via a dash-mounted switch. Accepted four-wheel-disc antilock brakes were an industry aboriginal for full-size pickups, and ability rack-and-pinion council became accepted on rear-wheel-drive 1500 models.
Powertrain and ElectricsThe three accessible Vortec V-8s – 4.8-liter 4800, 5.3-liter 5300 and 6.0-liter 6000 – got a new valvetrain, redesigned pistons, a added adamant cast-iron block and bigger lubrication, cooling and sealing. Anniversary delivered added ability and a adulate torque curve, forth with bargain emissions and bigger NVH.Both five-speed chiral and four-speed automated transmissions were upgraded, and a Tow/Haul approach for the automated accustomed the disciplinarian to change about-face patterns while towing or carriage to accumulate the manual acknowledgment and abate about-face “busyness” on hills. Additionally new was Autotrac four-wheel drive (standard on the top LT trim and accessible on midrange LS models), which automatically transferred torque to the avant-garde arbor whenever rear-wheel blooper was detected.
The new electrical arrangement was a abundantly simplified Class II architectonics that bargain base to a minimum through a Bussed Electrical Center that centralized connections, adequate them from bane and fabricated them easier to service. New exoteric lighting provided daytime active lamps with automated lamp control, and a Z82 Trailering Appropriate Equipment Amalgamation added constituent connectors for bivouac lighting and electric bivouac brakes.
Refined InteriorNot alone was the ’99 Silverado’s berth beyond than the C/K’s for added allowance and comfort, it was additionally quieter and added refined. “Back in the 400 days, our calendar was abundantly approved cabs,” says Jeff Luke, who formed on C/K accumulation at GM’s Oshawa bulb in Ontario and became the Silverado’s arch architect by 2004. “Then bodies started attractive at auto trucks, abnormally with connected cabs, as affairs vehicles, and the 800 afflicted the game.
“We said we can accomplish a barter a adorable artefact for peoples’ lifestyles, a ancestors agent that offers all kinds of versatility forth with adequacy and performance. There was a big focus on refinement, forth with abbreviation accumulation and advancement capabilities, and we went to the absolutely boxed, hydroformed frame, a advance technology that added stiffness, took out a lot of accumulation and bigger ride, handling, council and NVH,” Luke said.
The 800’s all-new cab architectonics bigger structural candor for bigger NVH. Extended-cab models got added rear-seat legroom and a added adequate seatback angle. New seat-mounted assurance belts bigger rear-seat access, and a accepted third aperture offered the widest aperture of any half-ton auto with acceptable one-hand operation. Additionally new was a faster and added able HVAC arrangement and a Disciplinarian Message Center that monitored and appear on basic agent functions.
Chevy accustomed the 800’s design, development and accomplishment processes as the best absolute and best computerized in GM history. Anatomy combinations and genitalia counts were reduced, the closing amid 170 and 300 per barter (depending on model) admitting college content, and all accumulation plants acclimated identical accoutrement and processes for bigger quality.
Continuous ImprovementThe approachable C/Ks remained in accumulation for agile sales during the 1999 and 2000 archetypal years, and the GMT800s connected the attitude of anniversary improvements. For 2000, the small-block V-8s delivered added ability and torque, and an alternative driver-side fourth aperture was offered on connected cabs. For 2001, absorption ascendancy for two-wheel-drive models and a blended box for four-wheel-drive 1500 connected cabs were offered, and GM’s OnStar account became accepted on top-line LT models. The 6000 V-8 was additional to 300 hp and 360 pounds-feet of torque. The aing year brought a new 1500 HD model, multiport ammunition bang (for California emissions) on 4300 V-8s, accepted automated manual on extended-cab models and, on some models, alternative Quadrasteer, which angry the rear auto adverse the fronts for a tighter axis amphitheater at parking speeds and in the aforementioned administration for added adherence at college speeds.
“We were actual appreciative of that Quadrasteer,” Luke says. “It was a abundant technology that bargain the axis ambit adequately dramatically, a abundant affair for a ample vehicle. It was adequately costly, and consumers at the time didn’t approach to it, but anybody who bought it admired it.”
Midcycle RefreshStill GM’s acknowledged vehicle, the 2003 Silverado got abundant upgrades. Beyond a new front-end architectonics were added than 40 new appearance and enhancements. Among them were cyberbanking burke ascendancy for small-block V-8s, a added avant-garde electrical architecture, dual-zone altitude control, dual-level airbags, new ball systems — including XM Satellite Radio, Bose stereo and a rear DVD amateur for aggregation cabs – and broadcast Quadrasteer availability.
That year additionally saw the addition of a high-performance Silverado SS, a monotone-painted extended-cab short-bed 1500 powered by a high-output LQ9 adaptation of the 6000 V-8 that pumped 345 galloping horses and 380 pounds-feet of pavement-wrinkling torque through a full-time adhesive all-wheel-drive alteration case. Accessible in black, red or brownish blue, the Silverado SS rode on 20-inch auto and tires on a bargain and stiffened Z60 high-performance anatomy package.
New for 2004 were 1500 and 2500 HD crew-cab models, broadcast Quadrasteer availability and accepted cruise control, ability aperture locks, AM/FM/CD stereo, upgraded wheels, chrome bumpers and atramentous bodyside moldings. The afterward year brought the industry’s aboriginal (for retail sales) gas-electric “mild hybrid” pickup, a 1500 connected cab powered by a Vortec 5300 V-8 accompanying to an electric motor through a four-speed automated transmission.
The amalgam powertrain additional ammunition abridgement up to 10 percent. “That was the aboriginal beheading anywhere of that blazon of technology,” Luke said. “It shut off the agent back you were chock-full and provided AC outlets in the cab and in the box, actual advantageous for contractors and added association that capital to use the barter for that affectionate of thing.”
Even in its final year, the GMT800 produced some affable surprises, including a new grille architectonics and a power-dome hood. To enhance the towing adequacy of four-wheel-drive 1500 extended- and crew-cab models, a new VortecMAX Achievement Amalgamation accumulated a high-output 345-hp 6000 V-8 with a able trailering package. An all-new Duramax 6600 turbo-diesel V-8 (good for 360 hp and a amazing 650 pounds-feet of torque) active through an appropriately new Allison six-speed automated debuted in HD Silverados. Availability of the amalgam broadcast to nationwide, and the SS amalgamation became accessible on two-wheel-drive trucks. A appropriate Intimidator SS adaptation was additionally offered to account the backward NASCAR disciplinarian Dale Earnhardt.
