Highlights

Blaze your own trail with this rugged and exceptionally capable Used 2021 GMC Sierra 2500HD AT4, now available at Stuckey Ford in Hollidaysburg! This formidable heavy-duty pickup truck is specifically engineered for serious off-road adventures and demanding conditions, while still offering premium comfort and advanced technology. It's the perfect vehicle for navigating the diverse landscapes of Pennsylvania, from challenging mountain trails around State College and Huntingdon to confident drives through Altoona and Johnstown, or tackling severe work challenges in Ebensburg and Bedford.

The 2021 GMC Sierra 2500HD AT4 boasts formidable power. It comes standard with the robust 6.6-liter V8 Gas engine, delivering a strong 401 horsepower and 464 lb-ft of torque, paired with a heavy-duty 6-speed automatic transmission. For even more extreme capability, many AT4 models are equipped with the legendary 6.6-liter Duramax Turbo-Diesel V8 engine, unleashing a massive 445 horsepower and 910 lb-ft of torque, paired with the advanced Allison 10-speed automatic transmission. The AT4 trim comes standard with an advanced 4x4 system and is specifically designed for off-road prowess. It features off-road-tuned Rancho shocks, a skid plate package (for transfer case and oil pan), and an Autotrac 2-speed transfer case, ensuring superior traction and control in varying conditions -- from snowy roads in Blair and Cambria Counties to muddy trails in Centre and Allegheny.

This Sierra 2500HD AT4 boasts impressive capabilities: a maximum conventional towing capacity of up to 14,500 pounds (with 6.6L Gas V8) or up to 18,500 pounds (with 6.6L Duramax Diesel) and a robust payload capacity of up to 3,979 pounds (with 6.6L Gas V8) or up to 3,715 pounds (with 6.6L Duramax Diesel), when properly equipped. This makes it ideal for hauling heavy trailers, large equipment, or substantial materials for jobs in Indiana or Greensburg. While EPA fuel economy ratings are not typically provided for heavy-duty trucks, the Sierra's powertrains are designed for efficient power delivery under load.

Step inside the Sierra 2500HD AT4's distinctive and well-appointed cabin. You'll find comfortable premium cloth seating with AT4-exclusive accents (or available perforated leather-appointed seating with Kalahari accents), and a leather-wrapped heated steering wheel. The GMC Infotainment System with an 8-inch diagonal color touchscreen (standard or available) keeps you connected and entertained, featuring seamless Apple CarPlay and Android Auto? compatibility, along with available Navigation. Other convenient features include Keyless Open and Start (with push-button ignition), Remote Engine Start, Dual-Zone Automatic Climate Control, and a power-sliding rear window.

Safety is paramount, and this 2021 Sierra 2500HD AT4 comes equipped with GMC Pro Safety. This comprehensive suite of driver-assist technologies includes Automatic Emergency Braking, Front Pedestrian Braking, Lane Keep Assist with Lane Departure Warning, Forward Collision Alert, Following Distance Indicator, and IntelliBeam auto high beams, providing enhanced peace of mind on every journey. Available features like Front and Rear Park Assist, Lane Change Alert with Side Blind Zone Alert, Rear Cross Traffic Alert, and a Rear Vision Camera further boost confidence when maneuvering this truck.

With its versatile bed, including the innovative Six-Function MultiPro? Tailgate (standard on AT4), this Sierra offers incredible flexibility for loading, unloading, and accessing cargo. The bed also features 12 standard tie-downs and available LED cargo-bed lighting.
