There have been many variations of the Chevy truck, dating all the way back to the 1930′s. However the first trucks to actually carry the moniker “Chevy Silverado 1500” were produced in 1999 and continued through 2008 when the extended cabs were produced. The truck is now available in both regular cab and extended cab versions.

A high performance version was introduced in 2003 called the Silverado SS. It included an ugraded trim package and a redesigned drive train was offered as well. The engine had been upgraded and included the 5.3 liter 285 hp (213 kW) 325 lbÂ·ft (441 NÂ·m) and also the 6.0 liter Vortec High-Output V8 rated at 345 hp (257 kW) at 5200 rpm and 380 lbÂ·ft (515 NÂ·m) of torque at 4000 rpm.
A military version of the truck is offered as well and is affectionately known as the Milverado and is being used by the US Army under the COMBATT (Commercially Based Tactical Truck) program. The GM bid beat rival bids from Chrysler (Dodge RAM 2500/3500), Ford (F-350 Super Duty) and Hummer (H1097A2 Wagon). While the platform is similar to the civilian issue Silverado, the military platform is understandabley heavily armored.
