The value-priced Work Truck package is now available on both regular and extended cabs. Base models pick up cruise control, a sound system, chrome rear bumper and chrome wheels. An automatic transmission is now standard on LS models, and the V6 is no longer an option in this trim. Other updates include new polished aluminum wheels and 265-70R16 tires with either black sidewalls or raised white lettering. The Quadrasteer option no longer requires the buyer to order trailering equipment. Theres also a new tonneau cover, and inside, youll find underseat storage. Finally, Chevrolet has deleted the Silverados passenger-side outside door lock.
