The 2011 Chevrolet Silverado heavy duty trucks have some exciting new features that make them the most exciting models to hit floors for awhile. From new frames to new technology, you will be surprised at how much you want this new Chevy heavy duty truck.
The 2011 heavy duty truck models all have new frames to improve ride and durability. Eleven all new full boxed frame assemblies with increased cross sections and more high strength steel give the trucks a higher towing capacity. The front sections are also hydro formed.
They also have a completely redesigned independent front suspension system that offers a greater front axle weight rating. This enables a snow plow to be used on all four wheel drive cab configurations. This improved suspension uses a pair of urethane jounce bumpers on each side instead of one for improved load management.
The heavy trucks also sport a new asymmetrical leaf spring rear suspension. It minimizes axle hop and enhances traction control efficiency. The 2500 models feature a two stage design, while the 3500 models have a three stage design.
There is a new powertrain combination of the Duramax 6.6L diesel and Allison 1000 six speed automatic transmission. This combo helps enable new features such as the exhaust brake system. This combination is expected to deliver the best fuel economy for this truck segment.
A powertrain also returns to the heavy duty trucks. The Vortec 6.0L gas V8 with variable valve timing with the strengthened version of the Hydra-Matic 6L90 six speed automatic transmission delivers excellent performance and efficiency. It also gives a greater emphasis on low rpm power.
Another new feature, only on the Duramax models, is an exhaust brake system. This is a driver selectable feature that uses the turbine control of the turbocharger and the compression of the engine to generate backpressure which slows the truck without applying the brakes. The brake system allows for effortless driving and teaming and prolongs the brake life and prevents overheating.
The brake feel and performance is also improved as the standard four wheel disc system was revamped to deliver smoother, immediate and confident feeling performance. The front and rear rotors are larger in diameter and width to support their increased capacity, weight ratings and trailering ratings.
The longer wheelbases and wider front/rear tracks also enhance the ride and handling characteristics of the 2500 and 3500. This gives them a greater feeling of smoothness and control.
There are many new safety features included now such as StabiliTrak electronic stability control system on the single rear wheel models, new high strength steel tubular frame cross member, seat pelvic/thorax and head curtain side air bags, available rear backup camera, trailer sway control system on single rear wheel models, hill start assist and segment exclusive OnStar 9.0.
