This 1984 GMC C/K 1500, listed as a Barn Finds Auction in Oklahoma City, is anything but a stock square-body pickup. Showing just 4,095 miles and carrying a clean title, this heavily modified GMC blends classic truck styling with a serious custom build underneath.

Power comes from a 5.0-liter (305 cui) V8 paired with a TH400 4-speed automatic transmission. A B&M Quicksilver shifter and shift kit are part of the package, adding a more performance-focused feel to the drivetrain. The engine bay is dressed up with polished pulleys, while the dual-exhaust routing includes an H-pipe and Flowmaster mufflers, with an X-pipe configuration.

Braking has been significantly upgraded with Wilwood disc brakes at all four corners. Out back, the truck features an independent Corvette rear suspension, a substantial departure from the factory setup and a clear sign this build was meant to stand out mechanically as well as visually.

Suspension modifications are extensive. It rides on Porter Built front and rear Level 3 Extreme Drop members that have been welded in place. Supporting components include Porterbuilt A-arms, trailing arms, and crossmembers. An Accuair self-leveling air system with programmable controller manages ride height, with the main compressor mounted on the engine and a backup air supply located in the bed. All hardlines are nickel-plated, reflecting the attention paid to the build details.

The exterior has been shaved extensively, with everything smoothed except for the door handles. Inside, Auto Meter gauges provide driver information, and the audio system is far from basic. An Alpine head unit feeds two Rockford Fosgate Punch 150 amplifiers, a Rockford Fosgate 300 running the highs, and a pair of 12-inch Rockford Fosgate Pro subwoofers.

This C/K 1500 represents a comprehensive custom effort rather than a light modification. From the Corvette independent rear suspension to the Accuair system and upgraded brakes, it’s a truck built to make a statement both parked and in motion. For fans of radical drops and high-end suspension work, does this 1984 GMC hit the mark?
