In the Chevrolet display at the SEMA show is a new, accessorized 2500HD Extended Cab Z71 equipped with the latest 6.6-liter Duramax turbodiesel engine and Allison 1000 six-speed automatic transmission. Some of the modifications, all of which are available options from Chevrolet, include a new Switchblade Silver paint finish, body-colored grille, 20 inch wheels painted in Corvette Competition Gray, a hard folding tonneau cover and custom graphics.
Also on display is a 3500HD “Race Car Hauler” pickup concept. Pulling a Chevy race car and trailer behind it, the Silverado 3500HD Crew Cab Dually also features the Duramax turbodiesel mill and Allison 1000 six-speed automatic transmission.
No powertrain modifications were made to the vehicle, but its exterior and interior wear a number of Chevrolet accessories and other aftermarket parts, as well as a few custom touches developed by Chevrolet’s own design team. Highlights include a full-width tool box and, on the inside, dual DVD headrests.
