When it comes to serious off-road driving in the Eastern Townships, two pickups stand out: the 2025 Chevrolet Silverado LT Trail Boss and the GMC Sierra 1500 AT4. Both models come with a factory suspension lift designed to handle everything from cottage access roads to more remote trails near Mount Orford. Although they share the same GM engineering foundation, each takes a different approach to off-road capability.
Both trucks offer a 2-inch lift and specialized off-road equipment, but the details make the difference when choosing a model suited to Quebec’s varied terrain. From rocky trails in the Laurentians to spring mud around Granby, understanding their differences can help determine which one best fits your adventure needs.
The Silverado LT Trail Boss offers three engine choices to suit different driving priorities. The 5.3L V8 produces 355 horsepower and 383 lb-ft of torque and is paired with a 10-speed automatic transmission, providing solid capability for most off-road situations. For more power on steep climbs or when towing heavy loads, the 6.2L V8 produces 420 horsepower and 460 lb-ft of torque.
For diesel enthusiasts, the available 3.0L Duramax Turbo-Diesel produces 305 horsepower and 495 lb-ft of torque. Its low-end torque makes it a strong choice for rock crawling or manoeuvres that require precise control at low speeds.
The GMC Sierra 1500 AT4 comes standard with the 3.0L Duramax Turbo-Diesel, giving buyers immediate access to 495 lb-ft of torque. The 6.2L V8 is available as an option, with the same 420 horsepower and 460 lb-ft as in the Silverado. With the diesel engine included as standard equipment, the AT4 delivers maximum torque right from the start.
Both models benefit from a 2-inch suspension lift, but there are some differences. The Silverado LT Trail Boss includes the Z71 Off-Road Package, with its lifted suspension, two-speed Autotrac transfer case and automatic locking rear differential. This setup is designed for versatility, moving easily from paved roads to moderate off-road excursions.
The Sierra AT4 combines its 2-inch lift with Rancho monotube shocks, designed to provide improved control on rough terrain. Its two-speed Autotrac transfer case and underbody skid plates help protect vital components during more aggressive off-road use. This setup is aimed at drivers who expect to spend more time off pavement.
Ground clearance and approach angles are suitable for more technical trails in both trucks, although exact measurements vary depending on wheel and tire choices. The factory lift provides enough clearance for most Eastern Townships trails while preserving the on-road comfort needed for daily driving.
The Silverado LT Trail Boss features a 13.4-inch touchscreen and an enhanced 12.3-inch Driver Information Centre, providing easy access to key vehicle data and infotainment controls. The cabin emphasizes practical functionality, with Trail Boss-specific trim designed to stand up to dirt and wear from outdoor activities.
The Sierra AT4 features an exclusive Jet Black interior with Kalahari accents and heated and ventilated perforated leather front seats. The cabin blends upscale comfort with durability, while an available 15-inch multicolour head-up display projects key information directly onto the windshield.
Both models come with Chevrolet Safety Assist or GMC Pro Safety, providing essential driver-assistance technologies for on-road driving and light off-road use. These systems help support control in demanding driving conditions.

The Silverado Trail Boss includes wireless Apple CarPlay and Android Auto, providing seamless smartphone integration for navigation during remote adventures. The Sierra AT4 offers similar connectivity through GMC’s infotainment system, with the available head-up display providing navigation directions without requiring the driver to look away from the road.
Both models offer OnStar connectivity for emergency assistance and vehicle diagnostics, including in areas where cellular coverage may be limited.
Off-road adventures often involve hauling equipment, boats or utility trailers to trailheads. Both trucks offer substantial towing capability, which varies depending on the selected engine and configuration. The Duramax diesel engines available in both models provide the torque needed to make towing on steep grades easier.
The decision between the Trail Boss and AT4 often comes down to priorities and budget. The Silverado LT Trail Boss offers several engine choices, allowing buyers to select the powertrain that best suits their needs. The Sierra AT4 includes the Duramax diesel as standard equipment, immediately providing maximum torque along with more upscale features.
Both models are well suited to Eastern Townships terrain, from the rocky trails around Mount Orford to seasonal roads leading to remote fishing spots. The choice comes down to whether you prioritize engine variety and value (Trail Boss) or standard diesel torque with a more premium level of comfort (AT4).
The 2025 Chevrolet Silverado LT Trail Boss and GMC Sierra 1500 AT4 both deliver the factory-ready capability needed to explore the Eastern Townships in depth.
