The Chevrolet Silverado and GMC Sierra trucks have been a pillar of American culture since their inception in 1975.
Compared to the first truck GMC ever made in 1930, the Sierra and Silverado series are fairly modern. Sierra and Silverado
pickup trucks have become household names for work and pleasure in a very
short time frame and owners all over America have been enjoying these trucks
for their power and comfort. In 2011 these trucks underwent some substantial changes. Although the trucks look similar to earlier models they came with an improved 6.6
liter Duramax diesel engine. This engine packs a huge gain in torque and some gains in horsepower, as well as some improvements in chassis and suspension components. The stiffer ride helps with steering response, handling on rough roads, and the vehicle's turning radius.
