What’s New for ’11
The redesigned chassis consists of 18 all-new fully boxed high-strength steel frame assemblies, additional cross-sections, and has five times the torsional stiffness of the outgoing model. Towing and payload capacities also are increased. The short-arm long-arm front suspension system features redesigned steel upper and precision-machined cast iron lower control arms with five separate torsion bar rates that can be selected depending on intended application and also boasts a 35% increase in gross vehicle weight rating than the outgoing model. Ride is further improved with an all-new asymmetrical rear leaf spring design that also increases payload capacity. The 6.6L Duramax diesel produces more horsepower and torque than its predecessor while emitting 63% less oxides of nitrogen (NoX). It also features a new exhaust “jake” brake to aid in controlling speed, especially on long downhill grades, extending brake life and preventing overheating. Glow plug cycling times are as low as 3 seconds, even in temperatures up to -20F (-29C) and are best-in-segment, according to Chevrolet. The Silverado also retains the 6.0L V-8 gasoline engine. Both the gasoline and diesel engine are mated to a heavy-duty Allison 6-speed automatic transmission with double-overdrive for more efficient high-speed operation. The standard 4-wheel anti-lock disc brake system has been recalibrated for improved pedal feel and boasts larger front and rear rotors and stronger calipers than its predecessor. Standard safety equipment includes stability control, available back-up camera, optional pelvic and head curtain side airbags (2500), a trailer sway control system and standard hill-start assist system that prevents rolling backwards when starting on an uphill grade on single-rear-wheel models.
- The Silverado HD exterior features a power dome-style hood with new louver design, new grille and full-width front chrome steel bumper.
