2009 GMC Sierra Crew Cab SLT Z71 All-Terrain 4x4
The Sierra was a virtual twin to the Silverado we tested, but outfitted with GMC’s All-Terrain package, which upgraded the high-end SLT trim and Z71 base offroad hardware with a handsome two-tone black and gray leather interior, Rancho shocks, 18-inch chrome-clad aluminum wheels and body-colored body-side moldings. It was also optioned with a navigation system. We felt GM’s navigation system was better than the Ram’s or Tundra’s. The Silverado, F-150 and Titan didn’t have navigation systems.
We thought the Sierra’s wheels and tasteful chrome accents made it among the most attractive trucks in the group, though the big rectangular All-Terrain badging was a bit much.
Unloaded and loaded ride and handling were similar to the Silverado’s, though noticeably stiffer in back thanks to the more aggressive offroad shocks. Trailer-towing ride and feel was virtually indistinguishable from the Chevy’s. Interestingly, our GMC tester didn’t come with more aggressive offroad tires, but rather had tires that were identical to the Silverado’s.
