DURAMAX DIESEL 6.6L V8 TURBO

The advanced DURAMAX diesel in the Sierra 3500HD delivers 397 hp and 765 lb-ft of torque, making it the most powerful Sierra ever. The DURAMAX diesel engine has a strong reputation and a proven track record, with nearly 1.4 million sold since 2000. Paired with the sophisticated Allison® 1000 Series transmission with overdrive, this available powertrain also offers a maximum highway range of up to 680 miles on a single fill-up.

DURALIFE™ BRAKE ROTORS

This ferritic nitrocarburizing technology is a GM-exclusive patented process that hardens and strengthens brakes. Duralife® protects against corrosion and can double the life of the brakes compared to conventional rotors.

ALLISON 1000 SERIES TRANSMISSION

The enhanced Allison 1000 is strengthened to handle the higher torque capability of the 6.6L DURAMAX engine, while also helping improve fuel economy and provide seamless assistance with the exhaust brake system.

DIRECT INJECTION TECHNOLOGY

For fast starts in cold Alberta winters, quiet operation and maximum efficiency, the direct injection system helps Sierra HD with the available DURAMAX diesel engine start in as little as 3 seconds at -40ºF. It operates at nearly 30,000 psi to turn heavy diesel fuel into a fine mist, delivering low emissions and great power.

SUSPENSION

Sierra 3500HD delivers a smooth ride with a fully independent coil-over-shock front suspension and 3”-wide multistage rear leaf springs, which engage progressively as the load in the bed or the hitch increases.

VARIABLE VALVE TIMING

From strong, steady power to bold acceleration on the highway, the 6.0L V8 with Variable Valve Timing (VVT) is up to any task by:

• Delivering power when needed and efficiency when less power is called for
• Monitoring and opening and closing valves for near-peak levels of torque across the entire range of engine speeds

EATON AUTOMATIC LOCKING REAR DIFFERENTIAL

No other competitor in its class offers a standard fully automatic locking rear differential for on- or off-road use.

• Delivers added traction in driving and wheel-slip situations
• Senses a difference in speed between left and right rear wheels, and then locks to turn both wheels in unison

DRIVER CONTROL TECHNOLOGY

Stay confidently in command of your truck and whatever you may be hauling or trailering.

• Available Hill Descent Control allows for a controlled descent in rough terrain without use of the brake pedal
• StabiliTrak intelligently manages braking and throttle to help keep the vehicle on its intended path
• Automatic Locking Rear Differential delivers increased traction
• Driver Shift Control lets you shift gears up and down with the tap of the shift selector
