Duramax, Chevrolet and GMC Horse Power and Torque
This article is about the Chevrolet Silverado and GMC Sierra (GM) pickup trucks mated with Duramax diesel engine with some specifications and history. The Isuzu and GM coop'd the 6.6l turbo diesel engine design that has put Chevrolet and GMC on the map for consumers and diesel truck lovers. In 2001, the Duramax turbo diesel was introduced to the GM 3/4 ton, 1 ton trucks and commerical trucks. In 2004.5, the EPA required a catalytic converters (Cat) and exhaust gas recirculation (EGR) on the LLY engines. In 2008, the EPA again required stricter emissions and required the first Diesel Particulate Filter (DPF) as well as the Cat/EGR. In 2011, improvements were made in the emissions systems by the new Urea injection system that didnt hurt performance.
The Allison 1000 automatic transmission has been the in the large amount of GM trucks built with the Duramax however you could order a 2001-2007 GM truck with a ZF S6-650 manual transmission. Interesting enough, the ZF S6-650 manual transmission ZF Friedrichshafen AG was used in the 1999-2003 Ford F-250 and F-350 trucks previously. This transmission was discountinued in 2007 by GM.

Dodge Ram Cummins 5.9l 6.7l diesel engine specs
Dodge Ram Cummins 5.9l 6.7l diesel engine specs have changed a lot from 1989 to 2017. The Cummins corporation actually made the engines for the Chrysler corporation bda Dodge and Ram companies. All these Cummins diesel engines are inline 6 cylinders. You can find these Cummins engines in many Dodge Ram 2500, 3500, 4500 and 5500 truck models. The original design in 1989 to 1993 started with a 5.9l VE-Rotary pump and 12 valves. These engine produced 160 horsepower (HP) and 400 foot pounds of torque (lb-ft). In the next generation of 5.9l Cummins engines they would change the pump to a P-7100 from 1994-1998 but was still only 12 valves. These Cummins engines produced from 175 to 235 HP and 440-460 lb-ft torque. In the third generation of 5.9l Cummins engines they would replaced the pump with the VP44 model and would move to 24 valves from 1998.5 to 2002. These Cummins engines produced 235-245 HP and 460-505 lb-ft of torque. These Dodge Ram trucks were also the first to get a catalytic converters which were required for EPA regulations. The last generation 5.9l Cummins engines from 2003 to 2007 used HPCR pump and 24 valves. They have 305-325 HP and 600-650 lb-ft of torque. Cummins made a displacement change in 2007.5 to the 6.7l Cummins diesel. This new generation of 6.7l engines started to use a Diesel Particulate Filter (DPF) as well as a catalytic converter for new stricter EPA regulations. The new Cummins 6.7l engine from 2007.5 to 2015 had 350-385 HP and 865 lb-ft of torque. In 2016 Cummins broke the 900 lb-ft torque mark. For both 2015 and 2016 Cummins had broken the torque records for any massed produced road worthy vehicle in the United States.

So for all these readers who are looking for trucks for sale in Denver, here are some great tips for buying used pickup trucks in Denver:
- Be sure of what is your budget, your needs, your preferences, your affordability in terms of repair and maintenance costs, parking space available with you and your budget for the fuel expenses per month. It is important to understand the implications of all these factors in the model you choose. There might be a car available that may be your childhood dream, but it may be exactly opposite to your ground realities. DO NOT opt for such a pre-owned vehicle that would prove unsuitable to meet any or most of these parameters.
- Do your homework with the models you are eyeing. Researching is easy these days with so much access to user reviews online. Carefully evaluate the strong and weak points of each model and pitch them against your requirements. The model or vehicle best matching the pitch should be your natural choice.
- Your local auctions can be a smart choice for buying a pre-owned vehicle. You may have a slight disadvantage of inability to inspect the vehicle through a mechanic, but says the experience that you would get a better deal 9 out of 10 times.
- Never be in a hurry in buying a pre-owned car. Take your time and inspect a vehicle in broad daylight under the sun. Low light conditions or foggy weather would hide half the defects which would be evident in high light conditions.
- Having your own mechanic for vehicle inspection is the best aide you can have when you are out looking for pre-owned vehicle buying.
- Evaluating a pre-owned car owner is just as important as inspecting the car. The type of owner and his or her attitude or personality would tell a lot about how he or she has taken care of the car or disclosing the true facts about the condition of the vehicle.
