2022 GMC Sierra 3500 HD Chassis Cab Flat Bed

Features may include:

• AVAILABLE ALLISON 10-SPEED AUTOMATIC TRANSMISSION

The Allison 10-speed Automatic Transmission features closer gear spacing that allows the engine to operate in an optimal range at all times with varying load and terrain conditions. An available integrated Power Takeoff (PTO) feature is offered straight from the factory on the Allison transmission, so you can transfer power from the engine to aftermarket equipment, such as a generator or hydraulic pump†.

• Available Dual Alternators

Dual alternators are available on both gas and diesel engines that deliver a combined 390 amps to help power the accessories and tools you need to get the job done.

• Electric Parking Brake

The Electric Parking Brake momentarily engages the brake system to help prevent truck rollback when transitioning from brake to accelerator pedal or when parking on steep grades under certain conditions. Brake enhancements include extended-hold Hill Start Assist, which provides extra time to start uphill from a complete stop.

• Park Grade Hold Assist

Prevents movement when shifting out of park on a hill and moving a foot from brake to accelerator pedal by automatically applying brakes at each wheel for an extended period of time while trailering.

• StabiliTrak®

Sierra HD Chassis Cab’s electronic stability control system helps improve stability by detecting and reducing traction loss.

The advanced technology inside the Sierra 3500 HD Chassis Cab commercial truck helps keep you confidently connected to help you get the job done while on the road.
