A true OEM auto parts brand for GM and non-GM vehicles, ACDelco® offers a wide portfolio of parts designed to keep vehicles on the road longer. These parts work precisely and fit perfectly because they are designed, engineered, tested, and backed by General Motors. But ACDelco also carries aftermarket components that go through the same 18-step quality approval process as the OE parts. Whether customers choose OE or aftermarket, they’d get the same reliable performance, precise engineering, and superior reliability for years to come. ACDelco’s expansive product portfolio includes alternators, filters, batteries, brakes, belts and hoses, oil and fluids, and suspension parts. These products are made to meet GM and non-GM vehicles’ ever-evolving powertrain, collision, maintenance, and repair needs.
