Duramax 2500

The Duramax 2500 has long been the beating diesel heart of one of America's great lines of pickup trucks: The Chevrolet Duramax 2500 series. In 2001 General Motors introduced the GMC Sierra Duramax 2500, 3500 Series and similar Chevrolet Silverado trucks with the Duramax Diesel V8 6.6L engine and Allison automatic transmissions. This Duramax 2500 based application was extended to the medium-duty trucks of GMC Topkick and Chevrolet Kodiak in 2003 rated for 16,000 to 19,500 lb gross vehicle weight. The engineers of the Duramax Diesel V8 6.6L for the Duramax 2500 concentrated on two key features: the Duramax 2500 engine's amazing torque to haul or tow loads and its high-rev horsepower offering flexible, smooth highway travelling.

Duramax 2500HD Is A Truck That Does It All

GM's line of Duramax 2500HD medium duty pickups come with the option for the Allison/Duramax combination, but the engine in the variants of the Duramax 2500 receives different power and torque ratings. Both the Express/Savanna vans and the medium duty pickups have the option of regular production code Duramax LMM. Other than power specs, the engine housing is the only difference between the Duramax engine in the 2500HD/3500 trucks from the ones installed in the medium duty 4500/5500 pickups and vans. Duramax 2500HD options for medium duty pickups include a 330/620 or 300/520 power and torque rating to ensure that the Duramax 2500 delivers consistent power and performance.

Chevy Duramax 2500 LMM 6600 For Durability

The compelling product line-up for the 2007 Chevy Duramax 2500 pickup truck models in recent years consists of the newest Duramax LMM 6600 V8 Diesel Turbocharged engine, Chevy GMT900 and GMC HD. With 660 lb-ft of torque and 365 horsepower, backed by an Allison 1000 6-speed tap-shift auto transmission, the new Duramax 2500 diesel powertrain from GM leads the way. Comparable to the Duramax 2500 LBZ and LLY, the LMM Duramax 6.6L Diesel employs a variable-geometry turbocharger calculated to provide amazing low-speed response time and decrease emissions in the Duramax 2500 pickup trucks. The Chevy Duramax 2500 turbocharger is geared for up to 120,000 rpm and produces a max boost pressure of 20 pounds per square inch.

Duramax 3500 For The Really Heavy Hauls

Along with the Duramax 2500 and the Duramax 3500 pickup truck series, the all-around useful 2007 GMC Savanna and Chevrolet Express cargo vans are also available with the Duramax V8 6.6L turbo diesel engine. Somewhat redesigned for application in the vans, the Duramax LMM provides 460 lb-ft of torque and 250 horsepower. Supporting the engine in a somewhat similar manner to the Duramax 3500 pickup trucks is an individually tuned Hydra Matic 4L85E. This electronically controlled 4-speed auto transmission integrates the renowned General Motors grade-braking functionality.

The Build Quality Of The 2500 Diesel Duramax Trucks

Traditional strengths of the Chevrolet 2500 Diesel Duramax pickup trucks are in their incredibly powerful, resilient, endurable Duramax 2500 engines and over all, the entire Duramax 2500 powertrains. However, General Motors had taken some flak due to Duramax 2500 build quality, which was not optimal, and the use of fairly cheap materials in the cabin itself of the 2500 Diesel Duramax models which tarnished the reputation of the Duramax 2500 pickups.

The Success Of The Duramax Diesel 2500 Pickups

There is no doubt that the Silverado Duramax Diesel 2500 would have been far more successful if the interior materials had been made from better quality. That has been an ongoing problem for General Motors as pertains to the reputation of the Duramax 2500. However, the overwhelming towing and hauling capabilities and the renowned durability of the Duramax Diesel 2500 powertrain have kept American Chevrolet Duramax 2500 pickup truck enthusiast happy for many years.
