Buick & GMC Parts for Sale | Oak Lawn, IL

General Motors (GM) is the original equipment manufacturer for all Buick, GMC, Chevrolet, and Cadillac vehicles. That means that when you purchase a GM genuine OEM part, you’re getting the exact parts that are used during production or validated by GM for GM vehicles. GM-backed parts are a precise fit, quick to install, have verified build quality, and proven structural integrity — a guarantee that can’t be made for non-GM-backed aftermarket suppliers. 

Aftermarket parts target a wider range of vehicles, as they cater to many makes and models, and typically offer a lower price tag. While many aftermarket suppliers offer high quality parts, they don’t offer that same peace of mind that comes with getting GM genuine parts — that’s where ACDelco original equipment comes in. ACDelco, a subsidiary of GM, is the only GM-backed aftermarket parts supplier that creates parts for GM vehicles and most non-GM makes and models.
