About the GMC Sierra 2500

The GMC Sierra 2500 is a mechanical clone of the Silverado 2500, also produced by General Motors. Though the Sierra is aimed more at luxury than the Silverado, both offer nearly identical aesthetics and features. 

Like its sibling, the GMC Sierra 2500 is renowned for its robust reliability. Earlier generations, like the GMT800, are known to run indefinitely, with high-mileage examples reaching 300,000 miles and higher. The tried and tested combination of a 6.6L Duramax diesel engine and Allison automatic transmission has stood the test of time, remaining a constant throughout the model's entire production time.
