1987 GMC K15 Sierra Classic SWB 4X4 Pickup – A True Testament to American Craftsmanship

The 1987 GMC K15 Sierra Classic SWB 4x4 pickup is a quintessential example of American automotive ingenuity in the late 1980s. As a member of the revered square-body GM truck lineup, this model represents the final year of production for this iconic design. It was the year GM introduced throttle body injection (TBI) to improve fuel efficiency and reliability, and this particular example boasts a TBI 5.7L V8 engine, perfectly complemented by a 700R4 overdrive transmission, making it a standout among its peers.

Historical Snapshot

The GMC K15 was designed to meet the needs of hard-working Americans who demanded reliability, power, and versatility in their vehicles. By 1987, the square-body trucks had cemented their reputation for ruggedness and ease of maintenance. The addition of factory fuel injection marked a pivotal shift towards modernization without compromising the durability and simplicity enthusiasts loved. The short wheelbase (SWB) configuration added agility and style to the K15’s rugged functionality.

Detailed Features and Specifications

Exterior

This K15 Sierra Classic shines in Black Metallic paint, a tasteful update from its original white color (paint code WA5118A). Accentuating its robust styling are 15-inch 10-hole aluminum wheels wrapped in beefy 33x12.50 tires, giving it an aggressive stance ready for on- or off-road adventures. With dual fuel tanks and wheel lip moldings, the exterior reflects thoughtful engineering designed for long-haul dependability. A spray-in bedliner further enhances its utility while preserving the solid and painted bed floor.

Interior

The interior of this truck has been tastefully updated with a black stock-style upholstery, a departure from the original red (code 77I). It features a well-maintained bench seat and functional conveniences like power windows, power locks, cruise control, and tilt steering. The aftermarket Kenwood stereo paired with kick panel speakers ensures modern audio performance. A newer dash pad, gauge bezel, and LED dome light elevate the interior’s overall condition and usability.

Mechanical Excellence

Under the hood, the matching-numbers TBI 5.7L V8 delivers reliable power. Paired with the 700R4 automatic transmission, it offers smooth shifts and highway-friendly cruising. With a solid undercarriage and a New Process 208 transfer case, this 4x4 is ready for any terrain. Power steering, power front disc brakes, and factory air conditioning (converted to R134A) make driving effortless and enjoyable.

Maintenance and Condition

With just 74,079 actual miles, this K15 has a clean bill of health. Its CARFAX confirms a history free of accidents or structural damage and includes meticulous service records. Updates such as newer shocks, front and rear leaf springs, and a recharged A/C system demonstrate attentive care over the years. The truck’s systems, including lights, wipers, and cruise control, all function flawlessly. Even details like the radiator support and inner fenders show well, reflecting the truck’s overall solidity.

Why This Truck Stands Out

The 1987 GMC K15 Sierra Classic SWB 4x4 combines timeless style with modern conveniences and solid mechanical performance. Its mix of originality and thoughtful updates makes it a highly desirable classic. With its iconic square-body design, fuel-injected V8, and off-road-ready capabilities, this truck embodies the spirit of adventure.
