Chevrolet has entered a modified ZR2 in the Vegas to Reno race, which starts this Friday. If the ZR2 finishes, it's guaranteed a Class win, since it's the only entry in its class. It will be interesting to compare the ZR2 results with the semi-stock Land Cruiser and Raptors entered in this year's race.
Along with safety equipment, the race truck has a modified suspension. Here's the press release, which has a nice set of photos of the race truck.

Because the engine and emissions control equipment are stock, the race truck is registered for street use. The "HallZR2" license plate refers to Hall Racing, the shop that made the mods.
