CHEVROLET SUBURBAN AT 75: HISTORICAL TIMELINE

1935: Suburban Carryall introduced with a signature two-door body style that would last

through 1967. Power came from Chevrolet’s stalwart “Stovebolt” inline-six that produced

60 horsepower (45 kW) for the half-ton chassis.

1936: Hydraulic brakes introduced.

1937: New, streamlined exterior styling carried Art Deco cues, and horsepower from the

Stovebolt six increased to 79 (59 kW). NEW TECHNOLOGY: Safety glass is introduced.

1940: Sealed beam headlights debut, offering significantly improved visibility when

driving at night.

1947: The first significant redesign of the Chevrolet’s truck line – including Suburban –

since before the war. Torque from the inline-six engine was 174 lb.-ft. (217 Nm) at only

1,200 rpm, giving the Suburban excellent towing capability. NEW TECHNOLOGY: Flow-

through ventilation improves driving comfort.

1953: Tinted glass is offered for the first time.

1955: Revolutionary new styling is introduced midway through the model year. Known

as the “second series” design, it features a wraparound windshield and the elimination of

running boards – the body is flush with the fenders for the first time. The second series

model also introduces the ubiquitous small-block V-8. NEW TECHNOLOGY:

? Hydra-Matic automatic transmission

? 12-volt electrical system

? Tubeless tires.

1957: Factory-installed four-wheel drive is offered for the first time, with the famous

NAPCO-supplied “Powr-Pak” system.

1959: Positraction rear axle introduced.

1960: Chevrolet institutes the C/K designations to denote models with 2WD (C) and

4WD (K). Front-end styling is also new. NEW TECHNOLOGY: Independent front

suspension (torsion bars) is introduced.

1963: Stronger, ladder-type frame design debuts.

1965: Factory-installed air conditioning and rear-area heater offered for the first time.

1967: All-new styling of Chevy’s half-ton trucks is introduced, including Suburban. It

carries a unique three-door arrangement with a single door on the driver’s side and front

and rear doors on the passenger side. This configuration makes the Suburban popular

with ambulance companies. A host of new safety features becomes standard, including:

? Dual-cylinder brake system

? Energy-absorbing steering column

? Padded instrument panel

? Thicker laminated safety glass windshield.

1971: Standard front disc brakes and engines tuned to run on unleaded gas.

1973: A new generation of Chevy trucks is launched, with Suburban offered in a

conventional four-door body style introduced for the first time. Its 129.5-inch (3,289 mm)

wheelbase was only 0.5-inch (12.7 mm) shorter than the 2010 model’s. Also debuting is

the Suburban three-quarter-ton model, which could be had with a 454 big-block engine

that delivered 335 lb.-ft. of torque (455 Nm).

1975: Increased focus on interior comfort and amenities in the 1973 models bring more

customers to Suburban for use as a personal vehicle. Chevrolet responds with more

comfortable seats and greater amenities, including simulated buffalo hide vinyl

upholstery, wood grain dash inserts, fully trimmed door panels and more. NEW

TECHNOLOGY: Rubber front control arm bushings and new rear leaf springs greatly

improve ride quality.
