Highlights
THIS… is a 1997 GMC Sierra 1500 SLE, finished in Emerald Green Metallic with a gray interior.
- The attached Carfax history report contains multiple gaps, though it lists no accidents or mileage discrepancies for the given time period. It also shows that this Sierra has been registered to one owner in California since new.
- Factory equipment includes 15-inch wheels, cloth upholstery, power-adjustable front seats, a Delco Electronics stereo system, air conditioning, and cruise control.
- Modifications reported by the seller include a Whipple supercharger, a HyperTech Power Programmer transmission tune, a Truetrac differential, a TransGo transmission shift kit, Rancho RS9000 shocks, and an Autometer boost gauge.
- Introduced for 1988, and closely related to the Chevrolet C/K, the first-generation Sierra brought smaller cab dimensions than the previous “rounded-line” model while offering a roomier interior. It was offered in several configurations grouped under the GMT400 label, and the wide range of available engines, transmissions, and body styles ensured the truck remained competitive during a production run that lasted for over a decade.
- Power comes from a 5.7-liter V8 engine, rated at 255 horsepower and 330 lb-ft of torque in stock form. The supercharger and other modifications likely increase those figures, but a dyno sheet was not provided to confirm. Output is sent to the rear wheels via a 4-speed automatic transmission.
