The UAW strike at American Axle & Manufacturing Holdings Inc.’s Three Rivers plant began on June 1, 2026, halting axle production that supplies Chevy Silverado and GMC Sierra pickups. This stoppage creates a risk of assembly slowdowns if parts inventories are depleted.
Strike Halts Key Axle Plant
Nearly 1,000 hourly workers represented by the United Auto Workers staged a full work stoppage at American Axle’s Dauch facility in Three Rivers, Michigan, after the plant’s labor contract expired. The plant produces axles and related components used in GM’s full-size Silverado and Sierra pickup trucks, among the automaker’s most profitable vehicles. UAW President Shawn Fain called for the strike after the sides failed to reach a new contract.
American Axle said it remains open to continued bargaining and is seeking a competitive agreement, though detailed contract terms have not been disclosed.
Supply Risk to GM Trucks
GM builds Silverado and Sierra pickups at multiple assembly plants, with some sites directly dependent on axles from the Three Rivers facility. At least one GM truck plant had been running high-output schedules, including a sixth day of weekly production, increasing sensitivity to parts interruptions.
Reports indicate GM may have roughly two weeks of axle inventory at a major truck plant, after which production could slow or halt if the strike continues. GM said it is monitoring the situation and working with the supplier to minimize disruption. The risk depends on the strike’s duration; a short stoppage could be absorbed by inventory buffers, while a prolonged strike could affect GM’s ability to meet full-size pickup demand.
