Four Generations of the Chevy C10
The Chevrolet C10 is the most collected classic truck in America. From the rounded fenders of the 1950s Task Force to the aerodynamic OBS of the 1990s, each generation has its own character, collector base, and investment profile. This guide compares all four generations side by side so you can decide which is right for you.
| Generation | Years | Nickname | Design Era | Price Range (#2) | Investment Rating |
|---|---|---|---|---|---|
| Task Force | 1955–1959 | Apache | Rounded classic | $25,000–$70,000 | ★★★★☆ Strong |
| Action Line | 1960–1966 | W-Series | Transitional | $20,000–$50,000 | ★★★☆☆ Moderate |
| Squarebody | 1973–1991 | Squarebody | Boxy iconic | $30,000–$80,000 | ★★★★★ Best |
| OBS (GMT400) | 1988–1998 | OBS | Aerodynamic | $15,000–$45,000 | ★★★★☆ Rising |
Price ranges for #2 (excellent) condition short-bed fleetside models. Long beds are 30–40% less. Stepside beds add 10–15%. Values as of 2026.
Generation 1: Task Force (1955–1959) — "The Apache"
The Task Force generation introduced the "Apache" trim name in 1958 and is the most classic-looking Chevy truck. With its rounded fenders, wraparound windshield, and chrome grille, it looks like it belongs in a 1950s movie. The 1955–1957 models have the "egg crate" grille; 1958–1959 have the four-headlight "Apache" grille.
Engines: 235ci inline-six (standard), 265ci V8 (1955+, first small-block Chevy V8 in a truck), 283ci V8 (1957+). The 283 V8 is the most desirable — it's the first engine to reach 1 horsepower per cubic inch in a truck.
The 1957 Cameo Carrier is the holy grail of Task Force trucks — only 1,400 built, fiberglass bed sides, and values exceeding $100,000. The 1958–1959 Apache Fleetside is the most popular for restoration.
Generation 2: Action Line (1960–1966) — "The W-Series"
The Action Line (C/K series) was a radical departure from the Task Force. It introduced independent front suspension on 2WD models (C), coil spring rear suspension, and a completely new, more modern body. The "W" designation refers to the Stepside; "Fleetside" is the wide bed.
Engines: 235ci/250ci inline-six, 283ci V8 (1960–1963), 292ci inline-six (optional), 327ci V8 (1966 only). The 327 V8 is rare and desirable — only available in the final year of the generation.
The Action Line is the least collected C10 generation — it falls between the classic Task Force and the iconic Squarebody. This makes it the most affordable C10, but also the slowest to appreciate. Buy one if you love the styling, not as an investment.
Generation 3: Squarebody (1973–1991) — "The Icon"
The Squarebody is the most iconic American truck ever built. Its boxy, clean-lined design defined an era. The Squarebody introduced the trim levels that collectors care about: Custom Deluxe (base), Scottsdale (mid), Cheyenne (upper), and Silverado (top). The Silverado with wood grain interior is the most valuable trim.
Engines: 250ci/292ci inline-six, 305ci/350ci small-block V8, 454ci big-block V8 (rare, most desirable). The 454 SS (1990–1993) is the halo Squarebody — only ~4,330 built, all black, and values exceed $80,000.
The Squarebody has the broadest collector base, the most parts availability (including reproduction body panels), the most LS swap compatibility, and the most active auction market. Values have risen 15–20% annually since 2020. A clean short-bed Silverado 350 that cost $25,000 in 2020 is now $50,000–$65,000.
Generation 4: OBS (1988–1998) — "The GMT400"
The OBS (Old Body Style) GMT400 was the first aerodynamic Chevy truck. It introduced flush headlights, composite headlights, and a more modern interior. The OBS is the newest C10 generation and the most affordable entry point into classic Chevy truck ownership.
Engines: 4.3L V6 (standard), 5.0L/5.7L V8 (350), 7.4L V8 (454 SS, 1990–1993). The 454 SS is the most collectible OBS — same engine as the Squarebody 454 SS but in the newer body. The OBS 454 SS is currently undervalued compared to the Squarebody 454 SS.
