2026 Chevrolet Silverado 3500 HD 4WD Crew Cab 172 LT - Duramax 6.6L V-8 *direct injection*, *intercooled turbo* diesel with 470HP paired to an Allison 10-speed automatic. This heavy-duty Silverado blends stout low-end torque with diesel efficiency to handle towing, hauling and long highway runs while delivering predictable, controlled shifts. Wireless Apple CarPlay and Android Auto keep navigation, music and messages at your fingertips without a tangle of cords, so you stay connected and focused on the road. *Forward collision mitigation* constantly monitors traffic ahead and readies the vehicle to help reduce the chance or severity of a frontal impact, adding an important layer of proactive safety. *Front pedestrian impact prevention* helps recognize people in the truck's path and can initiate measures to avoid collisions, offering extra confidence around busy streets and parking areas. An integrated *mobile hotspot* turns the cab into a reliable online workspace or entertainment center so passengers can stream and stay productive without draining phone data. *Brake assist* senses emergency braking and applies maximum available stopping power to help shorten braking distances when split-second stopping is required. Cruise control with steering wheel controls lets you set and maintain highway speeds without taking your hands off the wheel, reducing fatigue on long trips and promoting steady fuel use. A responsive *touchscreen* centralizes audio, navigation and vehicle settings for quick, intuitive control so adjustments are easy and attention stays on driving. *Lane departure warning* alerts you if the truck drifts from its lane, helping you remain centered on extended highway stretches and reducing the risk of unintended lane changes. The diesel powerplant delivers strong durability and favorable fuel economy for a heavy-duty truck, making it well suited to high-mileage towing and regular commercial use. The *OHV* pushrod layout emphasizes usable low-end torque, giving the Silverado strong pull from low RPM-an advantage when launching with heavy trailers or heavy loads. An intercooled turbocharger increases the density of intake air for better power and efficiency under load, sharpening throttle response when you need performance most. Direct fuel injection provides precise fuel delivery for improved power and efficiency, helping the engine run cleaner and respond more efficiently to throttle inputs. Purpose-built for demanding jobs yet comfortable enough for daily use, the 2026 Silverado 3500 HD LT pairs robust diesel capability with modern connectivity and safety aids. If you need a truck that can tow, haul and keep a crew productive and protected, this Silverado is worth a closer look-schedule a test drive to experience its strength and refinement in person. *Harbor Chevy is the top destination for used vehicles in Southern California.* We provide an exceptional buying experience centered on quality, value, and trust.*A Century of Trust:* Family-owned and proudly serving Long Beach, Los Angeles, and Orange County since 1923. *Vast & Diverse Inventory:* An extensive selection of high-quality used cars, SUVs, Certified Pre-Owned Hyundais, and commercial vehicles. *Guaranteed Quality:* Every vehicle receives a certified multi-point inspection, professional detailing, and comes with a clean-title guarantee. *Exclusive Powertrain Warranty:* Select vehicles include our complimentary Lifetime Powertrain Warranty for long-term peace of mind. *Transparent Pricing & Easy Financing:* We offer upfront, market-based prices and a streamlined financing process for all credit situations.
