1970 Chevrolet K10
Factory four-wheel drive capability distinguished this half-ton pickup from its two-wheel-drive C10 counterpart, delivering improved off-road performance through a solid front axle, leaf-spring front suspension, and a dual-range transfer case.
The “Action Line” generation introduced cleaner styling with double-walled steel pickup boxes offered in both Fleetside (smooth-sided) and Stepside (fendered) configurations. Buyers could select 6.5-foot or 8-foot cargo beds, with the short box riding on a 115-inch wheelbase and the long box on a 127-inch wheelbase.
Engine options typically ranged from a 250 cubic inch inline-six to V8s including 307, 350, and 402 cubic inch units, with the 402 replacing the earlier 396 while often still referred to by that name. Available transmissions included three-speed and four-speed manuals, along with a Turbo-Hydramatic three-speed automatic that broadened the truck’s usability for everyday driving.
The Custom Sport Truck (CST) trim package added more upscale interior appointments—such as carpet, additional brightwork, and enhanced sound insulation, signaling Chevrolet’s move from purely utilitarian workhorses to multipurpose pickups suited for both commercial duty and personal transportation.
