GMC Sierra fans are getting a little more bite for their bark as the 2019 GMC Sierra AT4 looms on the horizon. GMC says the truck is a “unique formula” becasue it blends off-road capability with technology and refinement. The new Sierra was recently revealed amid strong sales. Earlier in March, Duncan Aldred, Global GMC Vice President, explained that SLT and Denali models account for 87 percent of the brand?s total crew cab sales.
And now a new AT4 coming is down the pipe.
Essential Equipment
This GMC special rolls out of the factory with a two-inch lift, two-speed transfer case, locking rear differential, and skid plates. The Rancho monotube shock absorbers, hill descent control, and traction select system each increase the truck’s 4×4 capability. And there’s even a suite of advanced safety features like Surround Vision, Lane Change Alert with Side Blind Zone Alert, and Front Pedestrian Braking. The GMC Sierra AT4 comes with three different wheel and tire combos: 18-inch wheels with all-terrain tires, or mud terrain-rated Goodyear Wrangler Duratrac tires, or the available 20-inch wheels with all-terrain tires. It’s your call.
