The GMC Sierra 1500 IV, specifically the Crew Cab Short Box configuration with the 5.3 EcoTec3 V8 engine and four-wheel drive, represents a significant iteration in GMC’s full-size pickup truck lineage. Produced from 2016 to 2018 as part of the GMTK2XX platform’s facelift, this variant aimed to balance capability, comfort, and efficiency within the highly competitive American truck market. This model year saw updates to styling, technology, and powertrain refinement compared to earlier GMTK2XX Sierras. It positioned itself as a versatile option for both work and family use, appealing to buyers needing a robust truck without the extreme capabilities – or price tag – of the heavy-duty Sierra models.

Powertrain & Engine Architecture
At the heart of this Sierra 1500 variant lies the 5.3-liter L83 EcoTec3 V8 engine. This engine is a member of GM’s small-block V8 family, known for its durability and relatively simple design. The “EcoTec3” designation signifies features aimed at improving fuel efficiency, including direct injection, variable valve timing, and cylinder deactivation. The L83 utilizes direct injection to precisely meter fuel into the combustion chambers, enhancing combustion efficiency and power output. The cylinder deactivation system, also known as Active Fuel Management, allows the engine to operate on four cylinders during light-load conditions, further improving fuel economy. The engine’s OHV (Overhead Valve) valvetrain contributes to its compact size and robust nature. The Hydra-Matic 6L80 six-speed automatic transmission was the standard pairing for this engine. This transmission is known for its smooth shifting and reliability, offering a balance between performance and fuel efficiency. The transmission’s gear ratios are tuned for towing and hauling, providing ample torque multiplication for demanding tasks.
Driving Characteristics
The 5.3L V8 with the 6-speed automatic delivers a comfortable and capable driving experience. While not as quick as the 6.2L V8 option, the 355 horsepower and 382 lb-ft of torque provide sufficient power for everyday driving and towing. The automatic transmission shifts smoothly and predictably, although it may occasionally hunt for the right gear during highway cruising. The four-wheel-drive system provides enhanced traction in inclement weather and off-road conditions. Compared to manual transmission equipped Sierras, the automatic offers greater convenience, particularly in stop-and-go traffic. However, it does result in a slight reduction in fuel economy and a less engaging driving experience. The Crew Cab configuration provides ample space for passengers, making it a comfortable choice for families.
Equipment & Trim Levels
The Crew Cab Short Box 5.3L 4WD Sierra 1500 typically came standard with features like air conditioning, power windows and locks, a rearview camera, and a basic infotainment system. Higher trim levels, such as the SLT and Denali, added features like leather upholstery, heated and ventilated seats, a premium sound system, and advanced safety technologies. Optional extras included a sunroof, navigation system, and a trailering package. Interior upholstery generally consisted of cloth on lower trims, with leather becoming standard on higher-end models. Dashboard configurations varied depending on the trim level, with higher trims featuring more premium materials and finishes.
Chassis & Braking
The Sierra 1500 IV utilizes a body-on-frame construction, providing a robust and durable platform. The front suspension features independent coil springs, while the rear suspension employs a traditional leaf spring setup. This configuration provides a comfortable ride and good load-carrying capacity. The braking system consists of ventilated discs at all four corners, providing adequate stopping power. Anti-lock brakes (ABS) are standard. The rear brakes are slightly smaller in diameter than the front brakes, reflecting the weight distribution of the truck. Stabilizer bars are included to reduce body roll during cornering.
Market Reception & Comparison
The 2016-2018 GMC Sierra 1500 with the 5.3L V8 and automatic transmission was generally well-received by critics and consumers. It was praised for its comfortable ride, spacious interior, and capable powertrain. Fuel economy was considered average for a full-size pickup truck. Compared to the 5.3L manual transmission variant, the automatic offered greater convenience but slightly lower fuel efficiency. The 6.2L V8 offered more power but came at a higher price. The Sierra 1500 also competed with the Ford F-150 and Ram 1500, both of which offered similar features and capabilities.
Legacy
The L83 5.3L EcoTec3 V8 paired with the 6L80 transmission has proven to be a relatively reliable powertrain. While some owners have reported issues with oil consumption, these are not widespread. The transmission is generally considered durable and capable of handling high mileage. In the used car market, these Sierras represent a good value for buyers seeking a capable and comfortable full-size pickup truck. Their relatively simple design and readily available parts make them relatively easy to maintain. The combination of capability, comfort, and affordability has ensured that these trucks remain popular choices among truck buyers.
