ACDelco does not manufacture wiper blades or any other part for that matter, they source all their products from other suppliers. When Delphi was part of GM, Delco was a division of Delphi and a manufacturer of parts. I worked for Delphi before and after the transition from GM, and when they separated GM kept the Delco brand name. All that being said, I would like to find out who ACDelco sources their wiper blades from because I’ve been impressed with the blades on my ‘21 Silverado.

I know this doesn't help much, but according to gmparts.com: https://www.gmparts.com/parts/wipers...cked%20by%20GM.

. . . they are everything but manufactured by GM. This strikes me as a super duper secret that we peasants will never be able to find out for sure because they really don't want us to know. It also strikes me that they might use a special formulation that the real manufacturer is not allowed to use on other products.

FWIW: I've had great luck with Rain-X wipers as far as quality goes. A little pricey at Walmart, but they clear well, don't skip or make noises for a reasonable lifetime, and survive rough ice well.

People tend to buy brand names they know and recognize. I work for a chassis parts manufacturer that we sell under our brand name as well a private label names for our distributors. Have had many shops tell me they hate our parts in our brand name but love them in the private label name box.

back to the subject of wipers, I’ve had good results with Bosch Icon. Probably made by the same manufacturer as Rain X that several other posts mentioned.
