2009 GMC Sierra 2500: What's New, Specs & Features
Last updated August 4, 2026

The biggest change for the 2009 GMC Sierra 2500HD is its revised trim lineup, with Work Truck, SLE, and SLT added for the year. Otherwise, this is a light update rather than a redesign, with the engines, chassis, and exterior styling largely carried over.
About the 2009 GMC Sierra 2500
GMT900 Sierra HD generation (2007-2010), third model year before the fully redesigned 2011 Sierra HD.
GMC marketed the Sierra 2500HD as a heavy-duty pickup that combined serious towing and hauling ability with a quieter, more polished cabin than many bare-bones work trucks. The core appeal was GMC’s "Professional Grade" promise: strong chassis hardware, multiple cab and bed layouts, available diesel power, and interiors that ranged from basic fleet-ready setups to premium comfort. For many buyers, the Sierra 2500HD stood out by blending real work capability with a more upscale look and feel.
The 2009 Sierra 2500HD ranges from the basic, job-focused Work Truck to the more comfortable SLE and premium SLT. Work Truck has durable vinyl seating and a rubberized floor, SLE adds everyday conveniences such as power accessories and cruise control, and SLT brings leather upholstery, heated power front seats, dual-zone climate control, Bose audio, and Bluetooth.
