Many automakers offer separate parts and performance accessories divisions, but General Motors is about to push forward with a huge new online store. The GM online parts sales program will offer tens of thousands of parts and accessories for all current brands under the auto giant’s umbrella.

The GM online parts store will offer 45,000 repair and maintenance parts for all of its brands. The catalog will include oil filters, engine and cabin air filters, brakes and brake components, belts, hoses, wiper blades, and more. Chevrolet, GMC, Buick, and Cadillac owners can order parts for home delivery or pickup at one of more than 800 participating dealers.

If you purchase a part through GM’s store, you’ll be eligible for rewards program points that can be used to pay for more parts and accessories, or to help cover a future repair bill at a participating dealer. GM says it’s also the best way to ensure that you’re getting authentic and warranted ACDelco and General Motors parts.

Looking at General Motors’ sales projections, the online store makes perfect sense. GM forecasts parts and accessories sales to grow into a $40 billion market by 2030. The automaker first launched an accessories catalog in 2015, and all 5,000 products are available online. General Motors plans to expand its online efforts in the future to include a fully digital EV sales process. GM says it wants to allow customers to “shop, purchase, and finance electric vehicles entirely online, with the option to transition to an in-store experience at any point in the process.” The approach means that buyers can sidestep dealers completely, but have a resource available for questions and concerns when they arise.
