OEM Parts vs Aftermarket Parts: What’s Best for Your Vehicle?

When your car needs collision repair, one of the first questions you might face is whether to use OEM parts or aftermarket parts. It’s an important decision that can affect the safety, appearance, and value of your vehicle.

So what’s the difference?

OEM parts are Original Equipment Manufacturer parts. These are made by your vehicle’s manufacturer and match the exact specifications of the parts that originally came with your car.

Aftermarket parts are produced by third-party companies. They are intended to function like the originals but are not made by the same company that built your vehicle. Quality and fit can vary widely between manufacturers.

At Global Collision Center in Garden Grove, we often recommend OEM parts for collision repair, especially if your vehicle is newer, still under warranty, or part of a luxury brand. Here’s why.

OEM parts offer a perfect fit because they’re made specifically for your vehicle. This helps maintain the look, performance, and structural integrity of the car. They also meet factory safety standards and usually come with a warranty.

Aftermarket parts may cost less, but they sometimes fall short in terms of quality, fit, or finish. In some cases, using aftermarket parts may affect your vehicle’s warranty or reduce its resale value.

If you drive an older vehicle or are looking for a more budget-friendly option, aftermarket parts might make sense in limited situations. For example, parts that are not visible or not critical to safety may be acceptable substitutes. Still, it’s always worth discussing the pros and cons with a certified repair professional.

You may also be wondering what your insurance covers. In California, you have the right to request OEM parts for your repair. However, whether they are covered depends on your specific policy. Some insurance providers may only agree to pay for aftermarket parts, while others may cover OEM parts if your vehicle is relatively new or still under warranty.
