The truck that can tow nearly anything

You must have a seriously impressive boat or camper if you need a GMC Sierra 3500 to tow it. This truck has commercial-grade firepower under the hood, and an available 10-speed Allison® transmission that can handle sending all that torque to the wheels with 2WD or optional 4WD. Smart tech makes towing massive loads as easy as driving to work, while the interior design and features will make you think you’re inside a luxury car. The GMC Sierra 3500 is for maximum-effort work, but it’s not difficult to drive or live with every day.

5 reasons to buy the 2024 GMC Sierra 3500

1. Tow all the weight 

Are you interested in working hotshot trucking? Get yourself signed up for heavy hauling with the 2024 GMC Sierra 3500 and its incredible towing power. GMC has turned up its 6.6L turbodiesel to 470 horsepower and 975 lb-ft of torque. The Sierra 3500 with a gooseneck hitch and the diesel engine has a maximum estimated towing capacity of 36,000 lbs when properly equipped.

Your cabin cruiser probably isn’t big enough to make the Sierra 3500 sweat.  

2. Pro towing features 

It’s not all about the engine here. Trailering options include available adaptive cruise control with smart towing, taking the worry out of high-speed highway hauling, and 14 available camera views that let you keep an eye on what is going on back there. The available ProGrade Trailering System with an in-vehicle trailering app offers info and options at your fingertips. There’s available smart trailer integration and even the traction control system has a tow/haul mode. With so much towing tech, it'll feel like all you need to do is steer.  

3. Select your truck 

You want your truck with exactly the right configuration and options. The GMC Sierra offers all those options, from cab and bed length, to 2WD or 4WD, and gas or diesel engines. Six trim levels range from base model work truck to SLT convenience features, AT4X off-road upgrades, and Denali luxury touches. High-tech ranges from cool stuff like a massive driver information screen and center infotainment, to the connectivity and charging features your kids need. There are thousands of possible configurations of the Sierra 3500, so keep looking until you find exactly the truck you want. 

4. Comfortable ride 

The Sierra 3500 is a work beast, but it’s surprisingly civil. The cabin is quiet and well insulated from the outside, and the suspension is designed for off-road use, so it makes easy work of bumps in the road. Your passengers will love the large and plush seats, with standard eight-way power adjustments, and the seats are optionally up to 12-way power adjustable with power lumbar support on higher trim levels. Dual-zone climate control and optional heating and ventilation of front and back seats let everyone get comfortable.    

5. Cool tech 

Most tech is useful, but almost all of it is cool to play with. Get your tech fix in the GMC Sierra 3500 with features like an optional driver’s heads-up display and standard Apple CarPlay® and Android Auto™ connectivity. There’s even the MultiPro audio system by Kicker® that puts a sound system inside the tailgate for blasting your favorite tunes at the tailgate party or playing focus music at the job site.
