Narrow year range (drag arrows to filter):
A bi-fuel system is available on 2500 HD models with the 6.0-liter engine and extended cab. With it, the truck can run on regular gasoline or compressed natural gas (CNG). Also, the Duramax 6.6-liter V8 diesel engine is now available on 3500 HD chassis cab models.
The 2011 Chevrolet Silverado HD's Duramax turbo diesel's power, torque, maximum conventional and fifth-wheel tow and payload ratings are best in class. Its fifth-wheel tow capability is 21,700 pounds, it can tow up to a 17,000-pound conventional load with its factory-installed hitch, and the Duramax is fully B20 biodiesel compatible.
Changes for 2009 include OnStar 8.0 which allows for Bluetooth capability and Turn-by-Turn navigation with Destination Download on vehicles equipped with the DVD navigation screen. A new rearview camera system is available on Extended Cab and Crew Cab models, and vehicle stability enhancement is added to the 2500 HD trucks with single rear wheels.
Building on the well-received Tahoe, Suburban and lighter-duty 1500 pickups, Chevrolet's Heavy Duty series brings increased capabilities, refined interiors and enhanced drivability. And, in a nod to Ford's Super Duty line, there's more to differentiate this newest Heavy Duty from its lighter-duty sibling.

"This truck is giving me too many transmission and brake problems. Truck has trouble shifting out of 2nd gear in colder weather. It slips or even stays stuck in 2nd gear at times. I've also started seeing a lot of build up around the transmission tail housing. Dealer has done everything but find fixes to the problems with the trans and brakes. I was reading a different KBB consumer review that had mentioned brake problems with their truck. The problems I'm having sound similar to that. This maybe a problem that many other owners are having. If you're looking for a 3/4 ton truck, I DO NOT recommend people buy this vehicle."

"Truck has been very reliable; Duramax motor and Allison trans. has plenty of towing power. I averaged around 16-17 mpg highway miles. Overall, I'm happy with the truck. According to Kelley Blue Book it has really held its value."
