The K5 Blazer was the smallest full-size SUV version of the Chevrolet C/K Truck family. It was added to the Chevrolet line in 1969. The full-size Blazer was replaced in 1995 by the Chevrolet Tahoe. In 1970, GMC introduced its own model of the truck, called the Jimmy.The Blazer name was also discontinued in 1994 and replaced by the GMC Yukon. However the Blazer has a re-design in 1992 in which would later become the Tahoe in 1995. Both were based on the short wheelbase trucks. They were available with either rear-wheel drive or four-wheel drive. The K5 Blazer and Jimmy had "full convertible" removable tops until 1975. In 1976, GM introduced a half-cab design that was less prone to leaks. It was slightly safer in a rollover accident. These half cabs also had a removable top section. It started at a few inches behind the driver/passenger doors all the way back to the tailgate.
