Chevrolet has been building trucks for over a century, and if you’re in the market for one—whether a classic C10 or a brand-new Silverado EV—understanding the generations helps you know exactly what you’re getting.

The history of Chevy trucks is a story of constant evolution. From humble workhorses that shared parts with cars to the tech-laden, luxurious haulers we see today, each generation brought something new. Let’s break down every major generation so you can appreciate the legacy and make a smarter buying decision.

TL;DR

Chevrolet’s truck lineage breaks into three main eras: the early car-based trucks (1918-1947), the iconic Advance Design and Task Force series (1947-1959), the legendary C/K series (1960-2002), and the modern Silverado era (1999-present), which now includes the all-electric Silverado EV. The C/K series introduced the “C” for 2WD and “K” for 4WD naming system and saw four distinct generations, including the beloved “Square Body” trucks of the 1970s. The Silverado name officially took over in 1999 and has gone through four generations of its own, with the latest models featuring advanced tech, diesel engines, and even fully electric powertrains.

Key Takeaways

• 1918-1947: Chevy’s first trucks were essentially cars with cargo boxes, including the 1918 One-Ton and the 1935 Suburban Carryall—one of the first SUVs.

The Early Years: 1918-1946

It all started in January 1918. Chevrolet’s first truck was the Model 490 Half-Ton, which was basically a car with stronger rear springs . You bought it as a “cowl chassis” for $595 and had to add your own cab and bed. A heavier-duty Model T One-Ton was also available for $1,125. Both were powered by four-cylinder engines, with the One-Ton limited to 25 mph.

Chevrolet’s first factory-built pickup with a cab didn’t arrive until 1930. The 1935 Suburban Carryall was a game-changer—a station wagon built on a half-ton truck chassis with a steel body. Chevy claims it was the first SUV . This era also saw trucks used heavily in WWII, with Chevy building military 6×6 trucks and even the 14-ton T17E1 “Staghound” armored car .

Advance Design: 1947-1955

After the war, trucks started becoming more than just work tools. The Advance Design series was the first major redesign since WWII, and it was a hit. These trucks were bigger, sleeker, and offered creature comforts like a roomier cabin, a glove box, a heater, and even an optional AM radio .

The 3100 Series from this era is a classic—its five-bar horizontal grille and rounded profile are instantly recognizable, and it even inspired the styling of the 2000s-era SSR retro truck .

Task Force: 1955-1959

The Task Force series brought a more modern look with an industry-first wraparound windshield and integrated headlights . This is where the Cameo Carrier debuted, a stylish truck aimed at suburbanites with a fiberglass “Fleetside” bed that made the cab and box look like one smooth unit .

This was also the era when the small-block V8 engine—a legend in the making—became available in a Chevy truck . Power steering and power brakes also became options. For 1958, the light-duty trucks were named the Apache, with medium-duty called Viking and heavy-duty called Spartan.

The Legendary C/K Era: 1960-2002

The C/K series is where Chevy truck history gets deep. The “C” stood for two-wheel drive, and the “K” stood for four-wheel drive . This truck was built from the ground up as a truck, not a car with a bed, and it set the stage for everything that followed.

First Generation C/K: 1960-1966

This first generation was a massive leap forward. It rode on a drop-center frame that lowered the cab and gave it a car-like feel, and two-wheel-drive models got independent front suspension—a big deal for ride quality . For the first time, Chevy offered a factory-developed 4WD system . The 1960 models also debuted Chevy’s small-block V8 in a truck, and by 1965, nearly half of all Chevy trucks sold since 1918 were still on the road .

Second Generation C/K “Action Line”: 1967-1972

This generation is often called the “Action Line” , and it’s considered by many to be one of the best-looking trucks ever made . The styling was clean and pure, with a strong shoulder line and the iconic Chevrolet bar on the front fascia .

This was also when things got more comfortable inside. You could get an AM/FM radio, carpet, bucket seats, and even two-tone paint options . A 396 big-block V8 was added to the options list in 1968, bringing serious muscle to the pickup world.

Third Generation C/K “Square Body”: 1973-1991

Officially called the “Rounded Line” , everyone knows these trucks as the Square Body. They have a massive following today for their rugged, purposeful look . This generation grew in size and comfort and introduced the Crew Cab and the C30 One-Ton Dually, considered the first modern heavy-duty pickup truck .

This generation also marks the first use of the Silverado name (as a top trim level) . Under the hood, you could get a diesel engine starting in 1978. Chevy built these trucks for an incredibly long time, with the half-ton versions ending in 1986 and the heavy-duty R/V series continuing through 1991 .

Fourth Generation C/K “GMT400”: 1988-2000

The GMT400 platform brought Chevy trucks into the modern era. Aerodynamics finally influenced the design, and the interior got a futuristic look with a low instrument panel . This generation introduced the Insta-Trac 4WD system, letting drivers shift in and out of four-wheel drive without leaving the cab .

For high-performance fans, the 454SS arrived in 1990—a sport truck with a massive 7.4-liter V8 . Extended cabs also became available. This generation was sold alongside the next one for a few years as the “Silverado Classic” until the 2000 model year .

The Silverado Era: 1999-Present

The C/K name was retired, and the Silverado became the official name for Chevy’s full-size pickup line .

First Generation Silverado: 1999-2007 (GMT800)

The first Silverado was based on the GMT800 platform . It was more aerodynamic and had a stronger, hydroformed frame. This generation introduced a new line of Vortec V8 engines and was the first pickup to offer standard four-wheel disc brakes and an automatic transmission with a Tow/Haul mode . The 2003 model got a facelift, and the high-performance Silverado SS with a 345-hp 6.0L V8 was also offered .

Second Generation Silverado: 2007-2014 (GMT900)

This generation brought more power and technology. It won the North American Truck of the Year award for 2007 . The frame was upgraded for rack-and-pinion steering, and the engines received Active Fuel Management cylinder deactivation to save gas.

The Silverado Hybrid was available from 2009 to 2013, and a 6.2L V8 with 403 hp joined the lineup . This is also when Bluetooth, backup cameras, and side curtain airbags became available or standard.

Third Generation Silverado: 2014-2018 (K2XX)

Chevy dropped the GMT platform name for K2XX . These trucks were lighter thanks to more aluminum and high-strength steel, and they featured a new octagonal center stack housing the MyLink touchscreen infotainment system . This generation introduced the CornerStep rear bumper, a simple but brilliant innovation for getting into the bed .

The 6.2L V8 pumped out 420 horsepower, and a new 4.3L EcoTec3 V6 replaced the old workhorse six-cylinder . A mid-cycle refresh in 2016 updated the grille and headlights.

Fourth Generation Silverado: 2019-Present (T1XX)

The current Silverado generation is the most advanced yet. It was introduced at the 2018 Detroit Auto Show to celebrate Chevy’s 100th anniversary of making trucks . Weight was cut by up to 450 pounds, and new powertrains included a 2.7L turbocharged four-cylinder and a 3.0L Duramax diesel, alongside the carryover 5.3L and 6.2L V8s .

For 2022, the off-road-focused Silverado ZR2 arrived, complete with a lifted stance, spool-valve dampers, and 33-inch tires . In 2024, the heavy-duty models got a major refresh, and the lineup expanded further with the fully electric Silverado EV.

The Mid-Size Trucks: Colorado and S-10

Chevy’s mid-size truck story is also worth knowing. The S-10 was introduced in 1982 and ran through 2004, offering a smaller, more maneuverable alternative to the full-size trucks .

It was replaced by the first-generation Colorado in 2004, which was built through 2012 . The second-generation Colorado launched in 2015 and was a massive hit, offering a diesel engine and the off-road-ready ZR2 model. A third-generation Colorado arrived in 2023, continuing the legacy of this capable mid-size truck.
