Generations and History of Chevrolet 3500 Extended Cab
First Generation (GMT800; 2001-2007)
The first generation of the Chevrolet Silverado 3500HD was introduced for the 2001 model year, built on the GMT800 platform. This generation marked a significant step up in capability from the light-duty Silverado 1500. The Extended Cab models offered rear-hinged back doors for easier access to the rear seating area. Engine options were robust, featuring the Vortec 6.0L V8, the powerful Vortec 8.1L V8, and the highly-regarded 6.6L Duramax LB7 turbo-diesel V8, which was a collaboration between GM and Isuzu. The Duramax diesel was paired with a heavy-duty Allison 1000 five-speed automatic transmission. A facelift in 2003 brought slight design changes and upgraded audio and HVAC controls. For 2005, another minor facelift was introduced. This generation was known for its durability, though later model years have seen some complaints regarding interior material quality and transmission issues in the 4L60e used with some gasoline engines. The GMT800 trucks built for the 2007 model year, after the new GMT900 platform was introduced, were sold under the “Classic” nameplate to distinguish them from the newer generation.
Second Generation (GMT900; 2007-2014)
The second-generation Silverado 3500HD, based on the GMT900 platform, was all-new for the 2007 model year and represented a major leap forward in design, interior comfort, and refinement. The heavy-duty models received distinct styling to differentiate them from the light-duty 1500 series. The Extended Cab featured 170-degree opening rear access doors. The standard engine was a 6.0-liter Vortec V8 with variable valve timing, producing up to 360 horsepower and 380 lb-ft of torque, paired with a six-speed automatic transmission. The optional 6.6-liter Duramax turbo-diesel V8 was also available, with power outputs increasing through the generation. A significant update for the 2011 model year introduced a fully boxed, high-strength steel frame, improved suspension, and an upgraded Duramax engine with 397 horsepower and 765 lb-ft of torque, which greatly increased towing capacity. However, this generation, particularly the earlier models from 2008-2012, has been noted for having more owner complaints regarding electrical, engine, and transmission problems.
Third Generation (K2XX; 2015-2019)
The third-generation Silverado 3500HD, built on the K2XX platform, debuted for the 2015 model year. This generation brought a more modern, squared-off design and a significantly upgraded interior with improved materials and technology. The Extended Cab was rebranded as the “Double Cab”. The cabin was quieter and more comfortable, with features like Chevrolet’s MyLink infotainment system becoming available. Engine options included the carried-over 6.0L Vortec V8 gasoline engine and an updated 6.6L Duramax turbo-diesel V8. For the 2017 model year, the Duramax engine received a significant power boost to 445 horsepower and 910 lb-ft of torque. This generation saw the introduction of more advanced safety features, such as Forward Collision Alert and Lane Departure Warning. While generally considered reliable, some owners have reported issues with the infotainment system and emissions-related components on diesel models. The regular cab was discontinued for the 2019 model year.
Latest Generation (T1XX; 2020-Present)
The fourth and latest generation of the Silverado 3500HD was completely redesigned for the 2020 model year on the T1XX platform. This generation features a bold and aggressive exterior design that further distinguishes it from the 1500 models. The truck is longer, wider, and taller, with a longer wheelbase for crew cab models, providing more interior space. The Double Cab configuration continues to offer a balance of passenger and cargo space. This generation introduced a new standard 6.6L V8 gasoline engine and a revised 6.6L Duramax turbo-diesel V8, both paired with an Allison 10-speed automatic transmission. The interior has been significantly updated with a larger touchscreen infotainment system and more premium materials, especially in the higher LTZ and High Country trims. Advanced trailering technology, including a multi-camera system, is a key feature of this generation.

The driving experience of a heavy-duty truck like the Silverado 3500HD is different from that of a light-duty pickup. While early generations were more utilitarian, later models have seen significant improvements in ride comfort and handling, thanks to advancements in frame design and suspension.
