Pre-Owned 2016 GMC Sierra 2500HD SLT

The 2016 GMC Sierra 2500HD SLT with the 6.0L Vortec gas engine occupies a very strategic position in the used heavy-duty truck market. While a massive percentage of 2500HD trucks were optioned with the expensive and complex Duramax diesel engine, the 6.0L gas V8 is highly sought after by buyers who want heavy-duty capability without the strict maintenance overhead, fuel costs, and emission-system headaches that come with a 10-year-old diesel.
1. The Bulletproof 6.0L Vortec V8
The iron-block 6.0L Vortec V8 (L96) engine is legendary for its simple, un-killable design. It produces 360 horsepower and 380 lb-ft of torque, sent through a heavy-duty Hydra-Matic 6-speed automatic transmission.
No Diesel Def Headaches: It requires zero Diesel Exhaust Fluid (DEF), has no complex diesel particulate filters (DPF) to clog up, and bypasses expensive turbocharger or injector repairs.
Fast Warm-Ups & Short Trips: Unlike a diesel engine, which can suffer mechanical issues if it doesn't run long enough to get up to high temperatures, the gas 6.0L handles short commutes, errands, and cold-weather starting effortlessly.
Cheaper Maintenance: Routine oil changes and repairs cost a fraction of what they do on a diesel engine, making this truck vastly cheaper to keep on the road long-term.
2. High-Capacity Towing and Superior Payload
Because a gas engine weighs significantly less than a heavy iron-block diesel engine, dropping the 6.0L Vortec into the front of the Sierra 2500HD actually increases the truck's legal hauling weight capacity.
Exceptional Payload Capacity: Features a maximum payload capacity of up to 3,1443,342 lbs (depending on cab layout). This means you can drop much more weight directly into the bedsuch as gravel, tools, or heavy pin-weight trailersthan a diesel version of the exact same truck.
Stout Trailering: Max conventional towing capacity is rated up to 13,00014,500 lbs, making it perfectly suited for hauling mid-sized dump trailers, horse trailers, or camper vans.
3. The Refined SLT Premium Interior
The SLT trim elevates the Sierra 2500HD from a simple fleet vehicle to a highly comfortable, quiet premium vehicle.
Upscale Accommodations: Standard premium leather-appointed seating, dual-zone automatic climate control, and power-adjustable pedals that can be customized to any driver's height.
All-Weather Cabin Comfort: Standard multi-level heated front seats (with many models featuring the upgraded heated steering wheel and ventilated/cooled front seats).
IntelliLink 8-Inch Infotainment: Houses an 8-inch color touchscreen system with crisp graphics, Bluetooth connectivity, a crisp rearview camera, and high-quality audio routing.
Inlaid Triple-Sealed Doors: GMC heavily engineered this generation's doors to sit flush inside the body frame rather than over the roofline, dramatically reducing wind noise and creating a remarkably quiet cabin at highway speeds.
4. Professional-Grade Utility & Handling
The 2016 model year introduced critical chassis technology that makes driving an empty or loaded heavy-duty truck much more cooperative:
Digital Steering Assist: Available on SLT trims, this advanced electronic power steering system continuously adapts to your driving conditions. It makes the steering wheel light and easy to spin at low parking lot speeds, then firms up perfectly on the highway to reduce fatigue on long hauls.
CornerStep Rear Bumper: Features integrated steps into the corners of the rear bumper and ergonomically placed hand grips in the box rail protectors, allowing you to easily step up and access items in the bed even when the tailgate is lowered.
StabiliTrak with Trailer Sway Control: Automatically detects when a trailer begins to wiggle behind the vehicle and applies precise wheel braking to pull the entire rig back into a straight line seamlessly.
