2019 GMC Sierra AT4 Tries to Elevate Off-Roading

The 2019 GMC Sierra AT4 has debuted as a new variant for the upscale truck that will focus on off-road capability.

Revealed just before the 2018 New York Auto Show, the Sierra is the first GMC ever with the AT4 moniker, which will soon expand to the rest of the GMC lineup over the next two years.

To beef up the Sierra’s off-road capability, the AT4 version comes standard with a tw0-inch suspension lift for increased ground clearance, AWD with a two-speed transfer case and a locking diff, skid plates, Rancho monotube shock absorbers, hill descent control, Traction Select System, red vertical recovery hooks, 33-inch all-terrain tires (or mud-rated Goodyear Wrangler Duratracs), 18 or 20-inch wheels, a 5.3-liter V8, and the multi-position tailgate that debuted on the regular Sierra earlier this year.
