WHY GM GENUINE PARTS AND ACDELCO?

For more than 100 years,† General Motors has pushed the limits of transportation and technology. We’re proud to have helped drive that innovation. And today, ACDelco is proud to stand with GM Genuine Parts as the only source for true General Motors Original Equipment. Installed in millions of GM vehicles each year, our OE parts fit exactly and function precisely because they’re designed, engineered and backed by General Motors.

But our GM DNA doesn’t stop with OE. Gold and Silver aftermarket parts from ACDelco follow the same 18-step quality-approval process. They’re the only aftermarket parts backed by GM, even if you use them on other makes and models. Whether you choose OE or aftermarket, we work to protect the integrity of our parts so you can get to work with confidence.
