Powertrain and performance
- EcoTec3 5.3L V8: factory-rated at 355 hp and 383 lb-ft of torque. The engine uses GM’s EcoTec3 technologies (direct injection and cylinder deactivation/Dynamic Fuel Management) to balance performance and efficiency.
- Automatic transmission: matched with a multi-ratio automatic gearbox (10-speed on this V8), calibrated for smooth shifts and optimized for towing and everyday driving.
- Drivetrain: rear-wheel drive is standard; four-wheel drive is available from the factory. Standard electronic stability control, traction control and a limited-slip/locking differential strategy are used to maintain control under load or low-traction conditions.

Exterior and utility
- Body and styling: Sierra’s signature bold grille and strong sheetmetal, with chrome or bright trim details typical of the SLT trim level. LED daytime running lights and LED headlamps are part of the standard exterior lighting package on many factory configurations.
- Wheels and tires: alloy wheels sized to the SLT specification (commonly in the 18–20 inch range) fitted with all-season truck tires.
- Cargo bed and tailgate: standard pickup bed with integrated tie-downs and LED bed lighting. The MultiPro Tailgate (multi-function tailgate with multiple positions and step access) is commonly included on SLT-level Sierra models from the factory to increase cargo access and functionality.
- Towing and hauling: factory-equipped towing hardware and trailer-ready wiring are provided. Standard trailer stability control and a trailer hitch receiver are part of the equipment; towing capacity varies by configuration and options.

Chassis and ride
- Suspension: tuned independent front suspension with a multi-link or coil setup and a solid rear axle with conventional leaf springs, configured to balance ride comfort and load-carrying capability. Stabilizer bars and tuned dampers help control body motion.
