The 2026 GMC Sierra 3500 HD brings smart technology to heavy-duty trucking. With its 13.4-inch Premium GMC Infotainment System featuring Google built-in apps, drivers in Scranton get navigation, voice assistance, and entertainment on one large touchscreen. Wireless Apple CarPlay and Android Auto make it simple to stay in touch while keeping your hands on the wheel.
Safety technology helps you work with confidence. HD Surround Vision gives you a bird's-eye view around your truck, while the In-Vehicle Trailering App monitors your trailer's tire pressure and electrical systems. Vernon drivers will appreciate features like Trailer Side Blind Zone Alert and the available Multicolor 15-inch Head-Up Display that puts important information right in your line of sight.
The GMC MultiPro Tailgate offers six different positions for loading and unloading. Premium Bose audio systems deliver clear sound through multiple speakers. From the power-retractable assist steps with LED lighting to the wireless charging pad, every tech feature serves a purpose.
