General Motor’s pickups are doing really well, thank you very much – which is why the automaker has just announced another major truck plant expansion.

Following the capacity increase of full-size pickups in Fort Wayne, Indiana, The General has announced a major expansion of heavy-duty pickup capacity at its Flint Assembly in Michigan.

GM will invest $150 million at the facility to increase the production of the all-new Chevrolet Silverado HD and GMC Sierra HD pickups. The announcement comes just as the trucks begin shipping to dealers this week and the investment will go towards enhancing the plant’s conveyors and other tooling to increase production capacity, with the work to be completed in the first half of 2020.

“We have tremendous opportunities to grow our heavy-duty pickup business because we’ve invested in capability, performance, innovation, and capacity,” said GM president Mark Reuss. “Our all-new Chevrolet and GMC HD pickups are the toughest, strongest, most capable heavy-duty pickups we’ve ever brought to market, and our Flint team is up to the challenge to build world-class quality products to drive the growth.”

Since 2013, the automaker has invested more than $1.6 billion in Flint Assembly, with the latest one enabling an increase in production capacity of the all-new Silverado HD and Sierra HD pickups by about 40,000 vehicles annually, including more crew cab models and diesel versions. This year alone 1,000 new jobs were created, bringing total employment at the plant to more than 5,000 people working in three production shifts.

This move is the latest in a series aimed to strengthen GM’s truck, SUV and crossover business in the United States. Previously announced investments include Dayton, Ohio; Parma, Ohio; Romulus, Michigan; Toledo, Ohio; Spring Hill, Tennessee; and Lansing, Michigan.
