Powered by the same 6.6-litre Duramax turbo-diesel V8 producing 332kW and 1234Nm as the Silverado 2500 models already available, the 3500HD LTZ also runs the same Allison 1000 6-speed auto transmission, all-wheel drive system and most of the same interior features in its dual cab body.
The main difference, though, is in payload and towing capacities. Where the 2500 models have a payload of up to 975kg and maximum towing capacity with a pintle hook hitch of 5,890kg, the 3500HD LTZ’s maximum payload is 2,198kg, with maximum braked towing capacity, again with a pintle mount, at a massive 9,000kg.
The 5,908kg GVM puts the 3500HD LTZ well above the limit for use with a car licence, so buyers will need a heavy vehicle licence. Buyers will also need $147,990 (+ ORCs) to put the Silverado 3500HD LTZ in their (large) garage. This is $33,000 more than the entry-level Silverado 2500HD WT and $8,000 more than the 2500HD LTZ special editions.
