The 2019 GMC Sierra AT4 is now available with the all-new Off-Road Performance Package. The Off-Road Performance Package adds factory-installed performance upgrades that bring additional power and purpose to the Sierra AT4.
The Sierra AT4 Off-Road Performance Package includes:
– 6.2L V-8 engine mated to 10-speed automatic transmission.
– 18-inch machined aluminum 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 469 lb-ft of torque — increases of 15 horsepower and 9 lb-ft of torque over a Sierra equipped with a conventional 6.2L V-8 engine. The 6.2L is manufactured at GM’s Tonawanda engine plant in New York and was recently named a Wards 10 Best Engine for 2019.
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.
