General Motors said it will pump $328 million into its Flint, Mich., Assembly Plant to build next-generation Chevrolet and GMC full-size pickups.
The investment will create or retain 150 jobs, GM said.
The plant's 2,047 employees build the heavy-duty versions of the Chevrolet Silverado and GMC Sierra.
GM's retail share of the full-size pickup market has grown to 40.4% through May compared with 37.7% in the first five months of 2010, according to GM.
