A fourth door, on the drivers side, became available for extended-cab pickups, to supplement the standard right-side door. Silverados came in base, LS, and LT trim, with rear- or 4-wheel drive and a regular or extended cab. Both cab styles could be fitted with a flush-fender Fleetside cargo bed. The 6.5-foot flare-fendered Sportside box was available on certain LT models. Each of the two V8 engines gained 15 horsepower. A new self-dimming inside mirror went in LS and LT trucks. Power locks on those models could now be programmed to lock and unlock according to individual driver preferences. New options included wheel flares for 4x4s and a factory-installed cargo bed cover.
