1989 Chevrolet Pickup Dealer Info Sheet

What’s in the 1989 Chevrolet Pickup dealer information book

This is GM’s 1989 C/K Pickup dealer data book (revision January 1989), covering both Chevrolet and GMC versions. It lists every model with GVWR, maximum payload and engine/transmission availability, then covers the three trim levels, power-team charts by model, specifications, curb and option weights, and a model-by-model option selection chart. The standard Cheyenne/SL equipment list includes power steering, power front disc/rear drum brakes with a rear-wheel anti-lock system (operating in 2WD only on 4WD models), and a 25.0-gallon fuel tank.
