  The first Chevrolet pickup truck was introduced in 1924. More than 80 years later, Chevrolet trucks have developed over a wide variety of shapes, styles and sizes. In 1998, Chevrolet released its last version of the C/K line that later transformed into its current style of pickup trucks. This last generation of C/K trucks included an Off-Road Performance Package known as the "Z71." Today the Z71 package is available in several Chevy trucks and SUVs on the market.
