GM showed off their retooled line of Chevy Medium Trucks at the appropriately named Work Truck Show earlier this year in Indianapolis. Now, they’ve released pricing for the big brutes.

This segment represents the burly 4500HD, 5500HD, and 6500HD machines. When Chevy introduced the 2019 Silverado in Texas, execs said the nameplate would eventually migrate to its commercial line of trucks as well. This did indeed happen, delighting hard-working construction crews and builders of aftermarket bro-dozers alike.

Chassis cab trucks such as these are machines built with a cab but no bed or box. This makes it simple for companies to transform them into any number of creations, from walk-in delivery vans to ambulances and even Level Ten bro-dozers. The old Kodiak had the same amount of stylistic appeal as an industrial press. This Silverado makeover gives the truck with a dose of good looks, even if its double-deckered headlights do resemble Clark Griswold’s station wagon.

These Silverados will be available in regular or crew cab configuration with rear- or four-wheel drive. A 6.6L Duramax diesel engine making 350 horsepower and 700lb.-ft of torque is under its front-hinged clamshell hood, paired with an Allison automatic transmission. Chevy developed them in partnership with Navistar.

The engine in these trucks share displacement and Duramax marketing name with Chevy’s L5P engine found in 2500 and 3500 pickups where it makes 910lb.-ft of twist. Why the difference? This mill has unique injectors and is tuned for heavy grunt work rather than towing an RV on the highway. Emissions are more stringent for this heavier class of truck, too.

Prices start at $48,465 for a two-wheel drive regular cab 4500HD. Four-wheel drive motivation adds about $3000 to the bottom line. The model tops out with the 4WD 6500HD at $61,245. Both cab configurations are available in all three weight classes in either two- or four-wheel drive.

Other options? Gear ratios range from 4.10s to stout 4.88s, depending on how much one wants to tow or haul with their rig. GVWRs hit the ceiling at just under 23,000 pounds. Options include practical workaday gear like an air suspension, dual fuel tanks, and – in this digital age – all manner of connectivity. Its interior mimics that of the current Silverado.

This big beast, offering a wheelbase on the regular cab up to 243 inches, is expected to show up in over 400 commercially-focused Chevrolet dealers after factory production begins later this year.
