CHEVROLET SILVERADO 2500 HD

Overview

The 2026 Chevrolet Silverado 2500 HD is a full-size, four-door Crew Cab heavy-duty pickup sold in New Zealand in a single specification: LTZ Premium, powered by the 6.6-litre Duramax Turbo-Diesel V8. Like the Silverado 1500, every Silverado 2500 HD supplied to the Australia/New Zealand market is built by General Motors in left-hand drive and then re-engineered to factory-standard right-hand drive by GM Specialty Vehicles (GMSV), whose remanufacturing programme supplies both the Australian and New Zealand markets through GMSV's own New Zealand dealer network. IPAS sources this vehicle new, ex-works Port of Tauranga, New Zealand. Silverado 2500 HD is positioned as GMSV's heaviest-duty tow vehicle, built for larger trailers, equipment and caravans than the 1500 range is rated for.
