At Geoff Penske Buick GMC, we're proud to offer this latest Sierra HD to hardworking drivers throughout Shillington, Reading, and Lancaster, PA.

Performance: Duramax® Muscle Meets Intelligent Towing
Under the hood, the available Duramax® 6.6L Turbo-Diesel V8 engine means business. Paired with the Allison® 10-speed automatic transmission, this powerhouse delivers serious torque and towing capability. If you're pulling a trailer, boat, or construction equipment, you'll appreciate the max towing capacity of up to 36,000 pounds when properly equipped, enough to handle your largest loads confidently.
To make things easier, this heavy-duty truck comes with advanced trailering tech, including multiple camera views, Hitch Guidance with Hitch View, and in-vehicle trailering profiles. Backing into a tight space or lining up a gooseneck is easier, quicker, and safer.
Workday Comfort, Weekend Luxury
After a long day on the job or behind the wheel, you deserve comfort. The Sierra 2500HD brings it in a big way with generous head and leg room, plus available 16-way power front seats with built-in massage functionality.
The Denali Ultimate trim features an Alpine Umber interior lined with full-grain leather seats, laser-etched wood details, and even topographic maps of Mt. Denali stamped into the cabin. Its premium craftsmanship is designed for those who appreciate rugged style with refinement.
Stay Connected. Stay Aware. Stay Ahead.
The Sierra 2500's technology suite is built to help you work smarter and drive safer. The 13.4-inch center touchscreen gives you customizable access to navigation, apps, and your trailer profile. Meanwhile, a 15-inch multicolor Head-Up Display projects key info like speed and trailering alerts right onto your windshield, keeping your focus forward. The 12.3-inch Driver Information Center puts digital clarity at your fingertips.
On the safety front, Sierra HD Pro Safety is standard and includes Forward Collision Alert, Lane Departure Warning, Automatic Emergency Braking, IntelliBeam®, and more. This way, you'll have the peace of mind you need, whether towing a payload or an RV
