Chevy’s Silverado lineup of special edition models is welcoming a new member that’s largely based on this 2014 SEMA concept vehicle.

The ‘High Desert’ pack is available on LT, LTZ and High Country trim levels and is said to combine the new exterior styling and the all-new cargo system that’s both lockable and water resistant, with the available Magnetic Ride Control suspension.

The lockable storage system in the cargo bed is flexible enough so as to lock cargo away safely, while protecting it from the elements. The system also adds dual side storage bins and a three-piece hard tonneau cover.

Customers that buy the High Desert pack along with an LT trim level model will get 20″ wheels with all-season tire, while 22″ wheels and all-terrain tires are available on LTZ and High Country versions.

“The High Desert package blends the capability and utility of Silverado with the refinement and luxury of Suburban,” stated Sandor Piszar, director of Chevrolet truck marketing. “It’s ideal for those customers who want both the security of a lockable cargo area, as well as the flexibility of a pickup truck bed.”

This also happens to be the first Silverado offered with Magnetic Ride Control suspension, reading the road every millisecond and triggering damping changes in as little as five milliseconds in the electronically-controlled shock absorbers.

In terms of performance, the Silverado’s EcoTec3 6.2-liter V8 unit is available on LTZ and High Country models, as is the Hydra-Matic 8L90 eight-speed automatic transmission. With 420 HP and 460 lb-ft (623 Nm) of torque, this is the most powerful engine available now in a light-duty truck.
