Owner`s manual

we’re breaking new ground
in more ways than one.
If it matters to heavy-duty pickup owners, it matters to Chevy. So we engineered the new 2011 Silverado HD
with durable, advanced technology that makes this our most powerful heavy-duty ever. First, we
strengthened the available, proven Duramax 6.6L Turbo-Diesel V8 engine and Allison® transmission to generate
an earth-shaking 765 lb.-ft. of torque and 397 horsepower — more than the previous-generation Silverado HD —
plus towing capacities up to 21,700 lbs.

Next, we designed a high-strength, fully boxed steel frame with the
ability to handle more payload than before — up to 6,635 lbs.

And because it wasn’t enough to be just stronger
and sturdier, we gave you more heavy-duty driving confidence with innovative features that help keep the
mammoth loads you’re hauling under control. We even changed the look with bold updates to the hood, grille
and front bumper. Then we backed it all with our 100,000 mile/5-year
