The third generation of Chevy and GMC C/K series trucks had a long production run from 1973 to 1987 for the majority of the truck models and all the way to 1991 for Blazers, Jimmys, Suburbans, and 1 ton trucks. From 1973 to 1986 GM used "C" to designate 4x2 trucks and "K" for 4x4 trucks. To free up the C/K monikers for the all new 1988 GMT-400 truck, for the 1987 model year, using the 5th character of the serial number (VIN), General Motors redesignated full size 4x2 trucks as "R" models and 4x4 as "V" models. The R/V designations would continue to be used for 1988-1991 square body style models (Blazer, Jimmy, Suburban, and 1 ton).
