“The 2019 GMC Sierra AT4 debuted all-new, purposeful technologies for the premium truck segment and the new Off-Road Performance Package takes it a step farther,” said Duncan Aldred, vice president of Global GMC. “It offers optimized performance, both on- and off-road.”
The Sierra AT4 Off-Road Performance Package includes:
2L V-8 engine mated to a 10-speed automatic transmission.
18-inch machined aluminium wheels with Goodyear Wrangler®DuraTrac® tires.
Cat-Back Performance Exhaust System.
Performance Air Intake.
Thanks to these additions, the AT4 Off-Road Performance Package delivers up to 435 horsepower and 635 Nm (469 lb-ft) of torque — increases of 15 horsepower and 12 Nm (9 lb-ft) of torque over a Sierra equipped with a conventional 6.2L V-8 engine.
The Off-Road Performance Package’s upgrades build on the Sierra AT4’s distinctive formula of authentic off-road capability, innovative technology and bold design, along with GMC’s premium refinement.
The standard Sierra AT4 was introduced earlier this year, and content includes:
Standard 2-inch factory-installed suspension lift.
Standard 4WD with a two-speed transfer case, locking rear differential and skid plates.
Standard off-road-tuned Rancho®monotube shock absorbers.

Standard Traction Select System.

A full suite of advanced available safety features including Surround Vision, Lane Change Alert with Side Blind Zone Alert, Front Pedestrian Braking and Low-Speed Forward Automatic Braking5.
Building on the commanding presence of the next generation 2019 Sierra, the new Sierra AT4 enhances its confident, broad-shouldered stance with sophisticated, functional design elements that support its off-road capability.
The Sierra AT4 has a unique look driven by dark exterior finishes and modern detailing. The front and rear bumpers and the grille surround are finished in body colour, while the bold grille design with its rugged, knurled texture is finished in black chrome set off by the Sierra’s bold, C-shaped LED lighting signature.
Additional accent details such as the LED fog lamp bezels and fender trim continue the use of black chrome, while a premium high-gloss black finish is applied to the window trim, mirror caps and skid plate. Touches of red complete the package and make the AT4 stand out with subtle detailing in the Sierra’s all-new AT4 signature emblems and bold, unique vertical tow hooks. The exterior details create a distinct and modern personality for the AT4 that projects GMC confidence and capability.
The interior also carries AT4-specific darkened trim, including dark-tinted and textured aluminium finishes on the steering wheel, centre stack and sill plates, as well as a unique Jet Black/Kalahari colour accents in the seats and live stitching. Leather-appointed seating with embroidered AT4 badging on the headrests and all-weather floormats are standard and support our customers’ active lifestyles and AT4’s mission of delivering capability with uncompromising durability and comfort.
