FLINT, Mich. (AP) — General Motors says it will spend $150 million so it can make more heavy-duty pickup trucks at its Flint, Michigan, assembly plant.

The money will improve the factory’s conveyor system and for other equipment to boost output.

The factory builds heavy-duty Chevrolet Silverado and GMC Sierra pickups which are all-new for the 2019 model year.

No new jobs are tied to the Wednesday announcement, but GM announced earlier this year that it would add 1,000 workers at the plant. The factory now runs three shifts per day and employs about 5,000.
