For Sale: 1997 GMC Sierra in Marietta, Georgia

1997 GMC Sierra C1500 SL
69k Miles | 5.0L V8 | Rebuilt Automatic | 3.73 Posi | QA1 Suspension | Big Brakes

This 1997 GMC Sierra C1500 SL is a seriously well-built GMT400 that keeps the clean, classic single-cab look while adding the right performance upgrades in all the right places. Finished in Emerald Green Metallic over Gray cloth, this regular-cab, rear-wheel-drive short-bed truck has the stance, hardware, and documentation to back up its appearance.

Power comes from the factory 5.0-liter V8, now paired with a Black Bear Performance 0411 PCM swap kit, EFILive AutoCal V3 tuning module, Volant cold-air intake, and a custom-fabricated stainless header-back exhaust with Hooker stainless long-tube headers. The transmission has been rebuilt and fitted with a shift kit, while the rear has been upgraded with an Eaton Positraction limited-slip, 3.73 straight-cut gears, and Moser 30-spline axles and studs. Add in QA1 suspension, React drop spindles, Borgeson steering, and front/rear big brakes, and this is far more than just a clean OBS truck.

Exterior
Finished in Emerald Green Metallic, this Sierra presents exactly how a clean OBS GMC should - straight, clean, and understated, but with a much more aggressive stance than stock. The bright trim and bumpers contrast nicely with the deep green paint, and the single-cab short-bed proportions give it the look everyone wants.

The truck is equipped with a Wideside bed fitted with a black bed mat, and it also features an LS Fabrication Tailgate Saver gas strut kit for a cleaner, more functional tailgate setup. According to the documentation provided, the rear bumper was replaced in 2021, while later work included paintless dent repair, front bumper trim replacement, front bumper buffing, tailgate linkage replacement, and rear bumper adjustment. The headlights and taillights have also been replaced.

Relocated struts

Front track bar

QA1 1.25-inch rear anti-roll bar

Cruise control

Factory AM/FM/cassette stereo

The cabin presents honestly and cleanly, and the truck was also fitted with billet aluminum door strikes in 2023. The odometer shows 69k miles, with approximately 3k added by the current owner.

The Drive
This Sierra is the kind of OBS build that appeals to people who know what they are looking at. It has the clean look, the right color, the right wheel fitment, and a serious list of upgrades underneath. It is not just lowered for looks - it has real suspension, steering, rear-end, and braking upgrades that separate it from the average single-cab truck.

If you have been looking for a well-sorted GMT400 that combines low-mile appeal, documentation, tasteful modifications, and true performance-minded hardware, this 1997 GMC Sierra C1500 SL is a very strong piece.
