Chevrolet R20 problems
The third generation of the C/K series is a range of trucks that was manufactured by General Motors from the 1973 to 1991 model years. Serving as the replacement for the "Action Line" C/K trucks, GM designated the generation under "Rounded Line" moniker. Again offered as a two-door pickup truck and chassis cab, the Rounded Line trucks marked the introduction of a four-door cab configuration.
Marketed under the Chevrolet and GMC brands, the Rounded Line C/K chassis also served as the basis of GM full-size SUVs, including the Chevrolet/GMC Suburban wagon and the off-road oriented Chevrolet K5 Blazer/GMC Jimmy. The generation also shared body commonality with GM medium-duty commercial trucks.
In early 1987, GM introduced the 1988 fourth-generation C/K to replace the Rounded Line generation, with the company beginning a multi-year transition between the two generations. To eliminate model overlap, the Rounded Line C/K was renamed the R/V series, which remained as a basis for full-size SUVs and heavier-duty pickup trucks. After an 18-year production run (exceeded only in longevity by the Dodge D/W-series/Ram pickup and the Jeep Gladiator/Pickup), the Rounded Line generation was retired after the 1991 model year.
From 1972 to 1991, General Motors produced the Rounded Line C/K (later R/V) series in multiple facilities across the United States and Canada. In South America, the model line was produced in Argentina and Brazil, ending in 1997.
