The Most Powerful Duramax Diesel Ever

First and foremost, the new 2017 Chevrolet Silverado Duramax V8 diesel features a number of upgrades. These are largely based around the new high output engine. This new Chevrolet Silverado Duramax engine delivers more power, quieter running and increased efficiency than before. The upgraded Silverado Duramax engine includes upgraded pistons, crankshaft, rods, heads and turbocharger. This further bolsters the reliability and power associated with the Chevrolet Silverado name.

One instantly visible upgrade on the Chevrolet Silverado is the new bonnet scoop. This scoop draws over half of the air through a new patented air intake. In-turn providing a cooler intake temperature, increasing efficiency and further reducing turbo lag. Behind the new diesel engine is the ever reliable Allison transmission. It has also received upgrades in the form of a new torque converter and minor refinements to ensure the transmission handles the power that the new Chevy engine delivers.

Carrying The Load

The foundation of the Chevrolet Silverado HD lineup is a fully boxed steel chassis. This chassis uses large cross section, high-strength steel in key areas to provide one of the most stable and durable platforms available.

The stiffness of the frame contributes to improved handling and ride comfort, while the strength of the frames enhances payload and towing capability. The 2500 Silverado can provide up to 1,300kg on a car licence compared to Dodge Ram at just 945kg. Add front towing hooks, tubular cross members, multi-leaf rear suspension and adjustable front torsion bar suspension – the Silverado is ready to work.

The Chevrolet Silverado's independent double wishbone front suspension system offers a car like ride quality, the optimum in handling while maintaining front end durability for harsh off-road conditions.

Engine & Transmission


Pulling The Load

The Chevrolet Silverado continues its partnership with the Isuzu designed 6.6ltr V8 Duramax Diesel engine and the Allison 1000 series 6 speed automatic transmission.

The Duramax diesel produces an impressive 331kW and 1,233Nm of torque. With variable geometry turbocharger providing boost without turbo lag and a factory standard best in class exhaust brake fitted to help control heavy loads – much the same as in a full size heavy truck.

The Allison automatic transmission comes equipped with the Tow Haul mode. This unique system has the transmission shift adapt to better perform under heavy conditions as well as automatically gear down when headed down a hill or while braking.

Stopping The Load

Duramax diesel Chevrolet Silverado's allow the driver to engage the available diesel exhaust brake, which uses the variable vanes in the turbocharger to smoothly and quietly create additional back pressure in the engine, to slow the vehicle. The combination of the exhaust brake and the automatic transmission downshifts helps the driver maintain the desired speed, even on long, steep highway downgrades.

StabiliTrak Trailer Sway Control is now standard on all Silverado HDs, including 3500 Dual Rear Wheel models, providing additional security to the drive. Also, Hill start assist keeps the truck stationary for a few seconds after the brake is released, which gives you time to move forward before rolling occurs.
