The Chevrolet 2500-3500 truck is a tough, hardworking pickup that can compete with the best pickups that Ford and Dodge have to offer. The Silverado 2500 and 3500 come with the HD designation, representing "Heavy Duty," as in the ability to carry heavy duty loads and do heavy duty jobs.
The Chevrolet 2500-3500 trucks are the names most commonly given to the line of heavy duty pickup trucks from General Motors, particularly the Chevrolet Silverado. From 1988 to the year 2000, these trucks just went by these designations-the Chevrolet 2500 for the ¾ ton truck and the Chevrolet 3500 for the big one ton pickup. They were further designated by a "C" for rear-wheel drive and a "K" for four-wheel drive. Pre-2000 Chevrolet 2500-3500 trucks might have had the name Silverado, but at this time, this merely designated a trim level. In 1999, the light Chevrolet 1500 truck officially became the Silverado, and the following year, the 2500-3500 models followed suit, becoming the Chevrolet Silverado 2500HD and Chevrolet 3500.
The 2013 Chevrolet Silverado 2500HD and 3500 come with rear-wheel or all-wheel drive and a short or long wheelbase. The truck is attached to either a regular cab, extended cab or crew cab and there are three trim levels; the base no-frills Work Truck, the LT, which offers standard comfort and convenience features, and the loaded LTZ trim. The LTZ is only available with the extended cab or crew cab.
The Heavy Duty Silverado, which is sold under the GMC brand as the Sierra HD, comes standard with a 6.0-liter V-8 linked to a six-speed shiftable automatic transmission, generating 360 horsepower and 380 lb-ft of torque. For even more heavy duty power, 2500 owners can upgrade to the Duramax, 6.6-liter, Turbodiesel, V-8 engine that bumps the output to 397 horses and 765 lb-ft of torque, linked to a more muscular six-speed automatic, the Allison 1000, which is also featured in the Hummer H1 and Chevrolet B-Series. As Heavy Duty pickup trucks go, the Chevrolet 2500-3500 truck is a top of the line choice that many truck enthusiasts are very happy with.
The first generation of Chevrolet 2500-3500 trucks after receiving the Silverado name and HD designation appeared in 2001 and lasted until 2006, although there was a Silverado 2500 with an HD package available in 1999 and 2000, and the first Silverado 2500HD model could still be purchased as a "Classic" Silverado in 2007. This first Silverado-named version was distinguished from older Heavy Duty Chevrolets by a restyling of both interior and exterior in 2003 and more exterior changes in 2005. Although the top of the line LTZ trim was not available with this generation of Chevrolet 2500-3500 truck, the other trim levels, the base Work Truck, the LS and the LT, were all available.
This model came with a 6.0-liter, V-8 engine producing an impressive 300 horsepower and 360 lb-ft of torque. However, for those who needed more of a kick, there were two other engine options available: a 6.6-liter, Turbodiesel engine which offered 300 horsepower and 520 lb-ft of torque and an 8.1-liter V-8 which gave drivers 340 horsepower and 455 lb-ft of torque. Although the original diesel engine didn't offer any additional horses, in 2006 it was upgraded all around, with a better emissions rating and more power and torque, 360 hp and 650 lb-ft respectively. The standard engine was linked to a five-speed manual transmission or optional four-speed automatic, while the other engines were matched up with either a six-speed manual or a five-speed (six-speed in 2006) automatic.
The early years of the second generation of this heavy duty truck greatly resembled the prior version, but a design upgrade in 2011 provided a stronger frame, tougher suspension and more advanced technological enhancements. Second generation heavy duty Silverados initially featured a 6.0-liter V-8 that provided 353 horsepower and 373 lb-ft of torque, or a Duramax diesel engine which offered 365 horses and 660 lb-ft of torque. The current model offers a somewhat more muscular 6.0-liter V-8 that puts out 360 horses with 380 lb-ft of torque, or 6.6-liter Diesel offering 397 horsepower and 765 lb-ft of torque, linked to a six-speed shiftable automatic transmission. Rear wheel drive is standard and all-wheel drive optional. This truck has a flex-fuel engine appropriate for E85 fuel.
When properly equipped, this Heavy Duty model can to up to 1300 lbs. and haul up to 3670 lbs. These numbers are upgradable with the High Payload Package and a fifth-wheel connection.
The high-grade LTZ trim available with the crew and extended cabs offers such features as 18-inch alloy wheels, dual zone automatic climate control, Bluetooth, steering wheel mounted cruise and audio controls and upgraded audio.
