When Sumner drivers need real heavy-duty power, they come to Sunset Chevrolet, because Sunset is Trucks. What is it that powers the appropriately named 2021 Chevy Silverado HD models? Well, it depends on whether or not you’re satisfied with the already formidable 6.6L gas-powered V8 or if you’re looking for the superior torque of the 6.6L Duramax Turbo-Diesel V8.

Silverado 2500 & 3500 HD 6.6L V8

The first step for a towing and hauling upgrade from the Silverado 1500, the 2021 Silverado 2500 HD and 3500 HD have a 6.6L gas-powered V8 as their standard powertrain. Engineers crafted the V8 from a cast iron engine block for durability, and modern engine tech offers Puyallup and Tacoma pickup owners the perfect blend of performance, capability, and refinement.

With an engine rated at 401 hp and 464 lb-ft of torque, even the base Silverado HD pickup has plenty to offer, with 2500 models towing up to 14,500 pounds and 3500 models towing up to 17,400 pounds. Do you regularly have trailers that push those limits? Then keep reading for the 6.6L Duramax Turbo-Diesel V8 specs.

The 6.6L Duramax Turbo-Diesel features segment-exclusive air induction and a variable geometry turbocharger, delivering responsive torque and outstanding horsepower from Sumner to Auburn. Available as an option on the 2021 Chevy Silverado 2500 HD and 3500 HD, the 6.6L Duramax Turbo-Diesel is the standard 2021 Silverado 4500 HD engine.

Paired with a 10-speed Allison automatic transmission, the diesel engine is rated at 445 hp and 910 lb-ft of torque. The Duramax Turbo-Diesel’s most obvious appeal will come from maxing out your towing, with 2500 HD towing hitting 18,500 pounds and 3500 towing nearly doubling it at 36,000 pounds. The Silverado 4500 HD tows up to 16,500 pounds and has a chassis cab build that lets you outfit it exactly for what you need.
