Magnetic Ride Control's adaptive shocks can adjust the damping to suit the road surface in as quickly as five milliseconds. The shocks are filled with a magnetorheological fluid, which alters the damping rate nearly instantaneously. MRC is also known as MagneRide, and is used in many GM products, notably Cadillacs and high-performance Chevrolets, and even in some Ferraris.
As well as road-sensing capabilities, the High Desert package (which is available on the LT, LTZ and High Country trim levels) adds a water-resistant lockable storage system complete with dual side storage bins and a three-piece hard tonneau cover. Chevrolet offers the 420-horsepower EcoTec3 6.2-liter V8 on the Silverado LTZ and High Country versions, and the manufacturer says it's the most powerful engine available for light duty trucks. On the LT, the High Desert specific wheels are 20-inch, while on higher trim levels they are 22-inch.
The High Desert package will be in dealerships this fall. Pricing has not been announced yet. It should be noted that MagneRide is standard on the Silverado's sister model, the GMC Sierra, in the Denali trim level.
