GMC light-duty 1500 series went on sale late in 2006, and the heavy-duty versions follow in early 07?.



A concerted effort by General Motors to make enough changes the GMC Sierra than ever from the Chevrolet Silverado, its sister model, they succeed.

Once again the Sierra shares a platform with the GMC Yukon and GMC Yukon XL full-size SUVs. The models came first on this all-new platform, making their 07?-model unveiling earlier in 2006. The chooses are awesome : regular, extended and Crew Cab body styles; short, standard and long cargo box lengths; multiple powertrain combinations; five suspension packages; and four trim levels. Also there's also rear- or four-wheel drive.
