Sierra 3500

Spider

8-Cylinder Turbo

Big Power, Big Personality This truck doesn't just show up - it shows off. The 2025 GMC Sierra 3500 SLT Diesel is a heavy-duty beast with brains, brawn, and a whole lot of attitude. Under the hood, the Duramax diesel paired with the legendary Allison transmission delivers torque that laughs at steep grades and heavy trailers. If you've got something to tow, this truck says, Bring it on. But it's not all work and no play. Thanks to the X31 Off-Road Package, this Sierra is just as comfortable kicking up dust off the beaten path. With off-road suspension, skid plates, and hill descent control, it's ready to get dirty and still look good doing it. Inside, the SLT trim keeps things classy. You've got a quiet, comfortable cabin loaded with tech and premium touches that make long hauls feel like a cruise. Whether you're hauling equipment, heading to the mountains, or just rolling through town, this truck turns heads and handles business. Bottom line? This Sierra 3500 SLT is built to work hard, play harder, and look sharp every mile of the way.
