In addition to the usual raft of Corvettes and Camaros, General Motors will be bringing a pair of customized pickups to this year’s SEMA show. The full range of heavy duty GM trucks were revamped for 2011, and thus, the Silverado 2500 HD and 3500 HD will be on display.

First up, the SEMA-bound Silverado 2500 HD Z71 features a Switchblade Silver exterior color wrapped with custom Z71 graphics. Other exterior upgrades include 20-inch wheels painted in Corvette Competition Gray, a body-color grille, hard-folding tonneau cover, hitch-mounted winch, amber roof lamps and six-inch oval assist steps also painted in that special Corvette gray. Inside the truck, GM has fitted dual DVD headrests, mobile wi-fi and a Chevrolet Accessory trim plate kit. The modified truck is powered by GM’s new 6.6-liter Duramax diesel V8 and six-speed automatic transmission, which as we’ve found out in our testing, is one honey of a powertrain.

The second SEMA Silverado is a heavier-duty 3500 dually fitted for race car-hauling duty. After all, the Silverado 3500 is capable of towing up to 21,700 pounds, so one car on an open trailer is a piece of cake. The truck’s exterior has been painted black with custom racing graphics and adds visual touches like chrome hood louvers, 17-inch bright wheels, a custom grille insert, chrome fuel door and trailering mirrors, among other things. The interior gets the same upgrades as the 2500 Z71, and a 6.6-liter Duramax is found under the hood of this beast, as well.
