When upgrading your car parts or replacing broken components, you have an important choice to make: aftermarket or genuine Chevy parts? Genuine Chevy components are, without a doubt, superior to aftermarket parts when it comes to quality and longevity, so let’s explore what makes them the best choice for your car.

What Are Genuine Chevy Parts?

Genuine Chevy parts, also known as original equipment manufacturer (OEM) parts, are car parts manufactured by General Motors, which is the company that originally designed and manufactured the components used to build your car. These parts are made specifically for Chevy vehicles and are exact replicas of components in different Chevy models.

Why Should You Use OEM Chevy Parts?

Because of Their Superior Quality

Having the parts in your car manufactured by GM is an assurance of quality. Every single component is rigorously quality tested and made specifically with your Chevy model in mind. They’re made of the best materials that shouldn’t break down or cause problems with your car.

Because They Last Longer

The high-quality materials, Chevy-compatible design, and skilled craftsmanship used to make genuine Chevy parts ensure they’ll last a long time. They typically last much longer than aftermarket parts, as aftermarket parts are often crafted using cheaper materials and aren’t 100 percent compatible with your Chevy model.

Because They Fit Perfectly

Because genuine parts are designed for your Chevy model, they fit perfectly without being adjusted, and they work seamlessly with the other components in your car.

Aftermarket parts often require adjustment, as they’re made to be generic and fit relatively well into a vast number of cars from different automakers. They may not work seamlessly with your car’s other parts, and they may not be the perfect size to work perfectly with the other parts, even after being adjusted.

Because They’re Readily Available and Easy to Get Installed

Dealerships often keep many genuine Chevy parts on hand, and we can easily order the right components for you if we don’t already have them in stock. If you’ve already ordered the part you need directly from Chevy, then we’ll install that for you with no issues. If you ever need a new part but aren’t sure which component is right for your car, then you can always ask the dealership, as our technicians have extensive knowledge of Chevy parts.
