Chevrolet’s Silverado 2500 HD line of full-size three-quarter-ton trucks is built for hard work and maximum utility, with heavy-duty towing and hauling capacity, rugged construction, and a well-appointed interior. The 2025 Chevy Silverado 2500 HD continues that tradition with a tough, purpose-built truck offering comfort and capability.
Heavy-Duty Payload Hauling and Towing Capability
The Silverado 2500 HD embraces its hard-working roots with heavy-duty payload and towing capacity. The crew cab configuration of the 2500 HD can accommodate up to six adult passengers across its two rows of comfortable seating, and its 6.8-foot cargo box has 69.5 cubic feet of cargo volume and a maximum payload capacity of up to 4,200 pounds, depending upon engine and equipment selections.
If additional payload-moving capacity is needed, the Silverado 2500 HD has impressive towing capacity that gets the job done. The gasoline-powered 2500 HD has a maximum towing capacity of 18,700 pounds when properly equipped, while the 2500 HD with the Duramax turbo diesel can pull up to 22,500 pounds when outfitted with the proper equipment. It also has features like hitch guidance, hitch view, and an in-vehicle trailering app for simplified towing.
Two Dependable V8 Powerplants
The Silverado 2500 HD relies on two dependable V8 powertrains paired with either a 2WD or 4WD drivetrain. The standard engine is a gasoline-powered 6.6-liter V8 with a 3.73 rear axle ratio that’s matched with an Allison 10-speed electronically controlled automatic transmission with tow/haul mode and auto grade braking. Together, they generate 401 horsepower and 464 foot-pounds of torque.
The 2500 HD also offers a diesel powertrain option, with an available 6.6-liter Duramax turbo diesel with an exhaust brake, engine block heater, winter grille cover, 3.42 rear axle ratio, and an engine run-after feature that improves cooling performance. The Duramax, also paired with an Allison 10-speed automatic transmission, produces 470 horsepower and 975 foot-pounds of hard-working torque.
Technology That Improves Safety and Connectivity
Though the Silverado 2500 HD offers brute strength and purpose-driven capability, it also incorporates advanced technology that enhances safety and keeps drivers connected anywhere they may go. Its safety features include automatic emergency braking, forward collision alert, an HD rear vision camera, a following distance indicator, lane departure warning, front pedestrian braking, the StabiliTrak electronic stability control system, and six airbags.
The infotainment and connectivity amenities that come standard in the Silverado 2500 HD include a 3.5-inch driver information center, the Chevrolet Infotainment 3 System with a 7-inch color touchscreen display, wireless Apple CarPlay and Android Auto connectivity, Wi-Fi hotspot capability, a 6-speaker audio system, wireless phone projection, multiple charging and data ports, and Bluetooth streaming.
