2026 Chevrolet Silverado HD FAQ: Towing, Specs, Trims & More
The 2026 Chevrolet Silverado HD tows up to 36,000 lbs. with the available Duramax diesel and carries up to 7,234 lbs. of payload. The gas V8 produces 401 hp and 464 lb-ft of torque, while the diesel reaches 470 hp and 975 lb-ft. Every common question about trims, engines, safety, and technology is answered below, with inventory available at Jim Norton T-Town Chevrolet in Tulsa.
Powertrain & Performance
The standard engine is a 6.6L V8 gasoline unit rated at 401 hp and 464 lb-ft of torque. Every 2026 Silverado HD can also be ordered with the available Duramax 6.6L Turbo-Diesel V8, which produces 470 hp and 975 lb-ft of torque. Both engines pair with the Allison 10-speed automatic transmission.
The Allison 10L1000 10-speed automatic transmission is standard on every 2026 Silverado HD, regardless of whether the truck is equipped with the gas or diesel engine.
Yes. RWD is standard across the lineup, and 4WD is available on most configurations. Most popular trims, including the WT, Custom, LT, LTZ, ZR2, and High Country, can be ordered in 4WD.
The Duramax diesel delivers a significant capability advantage. Max available towing with the diesel reaches 36,000 lbs., compared to 19,080 lbs. with the gas engine. The diesel also produces more than double the torque (975 lb-ft vs. 464 lb-ft), which translates directly into pulling power at lower RPMs.
Towing & Payload
Max available towing with the diesel engine reaches 36,000 lbs. on a properly equipped 3500 HD. With the gas engine, max available towing reaches 19,080 lbs. The 2500 HD Crew Cab delivers segment-leading 5th-wheel/gooseneck towing of up to 22,070 lbs. Actual towing capacity varies by configuration, cab, bed, and equipment.

Max payload reaches 7,234 lbs. on a properly equipped 3500 HD Regular Cab DRW with the gas engine. Payload figures vary by cab, bed, drivetrain, and engine choice. Always check the door jamb label on the specific vehicle for its certified payload rating.
Yes. An integrated trailer brake controller is standard on all 2026 Silverado HD trims. This is a notable update for 2026, as it now ships on every configuration rather than being a standalone option.
Up to 8 cameras with 14 views are available, including Transparent Trailer View (which lets the driver virtually see through a connected trailer), Hitch View for easier alignment, and Bed View for 5th-wheel and gooseneck hitching. The In-Vehicle Trailering App lets drivers create a custom trailer profile, run pre-departure checklists, and monitor the connected trailer. Trailer Side Blind Zone Alert provides mirror alerts when vehicles enter the side blind zone while hauling.
