Chevrolet five window pickup 1951-images

Chevrolet’s postwar Advance-Design trucks hit the market a full year ahead of the competition, and by 1951 the line was refining details that collectors now prize above almost everything else — starting with the five-window cab option. New brakes, revised door windows, and a shorter cargo bed all arrived quietly that year. Here’s what made 1951 one of the more distinctive model years in the Advance-Design run.

Chevrolet was first off the line with a new post war design in May 1947–one full year before the competition. The new design offers superior visibility, with an 8 inch wider cab for more shoulder room and the truck is a foot longer overall than previously. The cab now has vent windows on each door and the 1951 model is the last year for the 80 mph speedometer. The engines available are a 216 cu in (3.5 L), a 235 cu in (3.9 L) and the 261 cu in (4.3 L) V8, There are two transmission choices-a four speed manual or the basic three speed manual.

Chevrolet beat every competitor to market with a genuinely new pickup design after World War II, and it wasn’t particularly close — the new trucks arrived a full year before rival automakers had anything comparable ready to sell. By 1951, that design was entering its final refinements before a bigger overhaul was still a few years away, and one option in particular has since become the detail collectors chase hardest. It wasn’t the engine, and it wasn’t the color. It was a pair of small windows tucked behind the doors that most buyers in 1951 probably never gave a second thought to ordering.

The Windows That Gave The Truck Its Nickname

The five-window cab was part of the Deluxe option on Chevrolet’s Advance-Design trucks, adding curved Nu-Vue rear corner windows for improved visibility over the standard three-window setup. The Advance-Design series debuted on June 28, 1947 and ran through the 1955 model year, and today enthusiasts specifically hunt down five-window cabs over the far more common three-window configuration.

What Actually Changed For 1951

The 1951 model year brought a mid-year change from a 9-board bed to an 8-board bed, added vent windows to the doors, and marked the last year for the 80 mph speedometer. Brakes were upgraded to duo-servo, self-energizing Bendix units, replacing the older Huck-type brakes. Power came from a 216 cubic inch inline-six rated at 92 horsepower and 176 lb-ft of torque, paired with a column-shifted three-speed manual transmission.

Why the Five-Window Cab Costs More Today

Because the five-window Deluxe cab was always the pricier option over the standard three-window configuration, fewer buyers checked that box new, and that scarcity has carried straight through to the collector market decades later. Enthusiasts specifically hunt for five-window trucks over their three-window siblings, and that preference alone can meaningfully separate two otherwise similar Advance-Design trucks in value.

The Advance-Design Series Set the Template for Decades

Chevrolet’s Advance-Design trucks, which ran from 1947 through 1955, established a formula of wider cabs, better visibility, and more car-like comfort that reshaped what buyers expected from a work truck. That approach proved influential enough that subsequent generations of Chevrolet pickups kept building on the same basic idea of making a truck comfortable enough for everyday driving, not just hauling.

A Six-Cylinder Truck in a V8 World

Unlike the muscle cars that would come to define American performance a decade later, this era of Chevrolet trucks ran exclusively on inline-six power, with the 216 cubic inch unit doing the bulk of the work in 1951 models. That six-cylinder foundation reflected the priorities of a working truck buyer in the early 1950s: durability and torque for hauling, not outright horsepower, a philosophy that wouldn’t fully shift until V8 power became standard truck fare later in the decade.

Gateway Classic Cars and the Restored Truck Market

Dealers specializing in restored and original classic trucks, like the one that supplied these images, have helped fuel a steady collector market for Advance-Design Chevrolets that might otherwise have been overlooked in favor of flashier muscle cars from the same era. A well-preserved or carefully restored 1951 five-window with its original inline-six intact represents a different kind of collecting priority: authenticity and craftsmanship over raw power.

What Made 1951 the End of an Era for This Design

The Advance-Design trucks would receive their first major styling refresh in 1955, meaning 1951 sat squarely in the middle of the platform’s run rather than at its beginning or end. The mid-year bed change from nine boards to eight, along with the switch to duo-servo brakes, reflected Chevrolet’s habit of continuously refining these trucks year to year rather than waiting for a full redesign to fix small issues.

Why These Trucks Still Draw a Dedicated Following

Advance-Design trucks occupy a unique space in the collector hobby: plentiful enough that parts and knowledge remain accessible, but distinctive enough in styling that they don’t blend into the broader pool of postwar pickups. Their rounded fenders, split windshield, and that coveted five-window cab option give them a visual identity that has aged well, helping explain why interest in clean original and restored examples has remained steady for decades.

The Broader Postwar Truck Market Chevrolet Was Chasing

Returning veterans and a booming postwar economy created enormous demand for reliable work trucks in the years immediately following World War II, and Chevrolet’s head start with the Advance-Design series let it capture a meaningful share of that market before competitors caught up with their own redesigned lineups. That early advantage helped cement Chevrolet’s reputation in the truck segment for decades to come, well beyond just the Advance-Design era itself.

How These Trucks Get Restored Today

Restoring an Advance-Design truck to this level typically means sourcing reproduction sheet metal for common rust areas, rebuilding the inline-six with period-correct components, and often upgrading brakes or electrical systems for practical everyday driving while keeping the exterior faithful to original specifications. That balance between usability and authenticity has become the standard approach among restoration shops that specialize in this era of Chevrolet trucks specifically.

The Legacy These Trucks Left for Chevrolet

The design principles established in the Advance-Design era, prioritizing cab comfort, visibility, and a more car-like driving experience, carried forward into every subsequent generation of Chevrolet pickup, right up through today’s trucks. Looking at a 1951 five-window alongside a modern Silverado reveals just how much of the underlying philosophy, if not the specific engineering, traces directly back to decisions Chevrolet made in the years right after World War II.
