Explore the 2025 GMC Sierra 3500 HD Chassis Cab

Engine Power

A commercial truck must have the power to tow or carry heavy loads, and the 3500 HD Chassis Club more than delivers. The standard engine is the 6.6L V8 gas engine that supplies 401 hp and 464 lb-ft of torque. Its compression ratio of 10.8:1 provides increased fuel efficiency and performance by enabling the engine to gain more energy during combustion.

You can also choose the available Duramax 6.6L Turbo Diesel V8 with its 470 hp and 970 lb-ft of torque. This engine includes a turbo vane actuator that precisely controls the flow of exhaust gases to the turbine wheel, increasing engine performance at both high and low speeds. Both engine choices are paired with a 10-speed Allison automatic transmission that provides fast and smooth power transfer to the wheels.

StabiliTrak

StabiliTrak is standard on the 3500 HD Chassis Cab to provide enhanced stability and control when towing, driving on wet, slippery surfaces, or when shifting out of PARK on a hill. It uses a network of sensors that monitor each wheel for speed changes, for example, if your vehicle or trailer starts to fishtail. It will then apply braking selectively to the affected wheel to get it back on track and keep your vehicle moving in a straight line.

Hill Start Assist is part of this system and prevents rollback when you start your vehicle on an incline of 5% or more. Even with an automatic transmission, gravity will steadily pull your vehicle backward as you shift into DRIVE. This system will automatically keep the brakes active for 1.5 to 2 seconds when you shift your foot from the brake to the accelerator, allowing you to safely and smoothly drive uphill.

Cab Options

The 3500 HD Chassis Cab has two cab options. The Regular Cab offers spacious seating for three people across one seat row, while the Crew Cab with four doors has comfortable seating for up to six people across two seat rows.

OnStar Vehicle Insights

This available feature helps your fleet operate even more efficiently by continually monitoring the vehicle and providing real-time information on its performance. This information includes fuel usage, maintenance needs, engine health, and driver behavior. It also enables you to improve route planning for increased productivity.

These are just some of the many reasons to choose the 3500 HD Chassis Cab. Contact us today at Criswell Commercial Trucks in Clarksburg, MD.
