OEM vs. Aftermarket Parts: What’s the Difference in Collision Repair?
When it comes to collision repair, one of the most important decisions made behind the scenes is whether to use OEM or aftermarket parts. It’s a choice that affects everything from fitment and quality to long-term performance and safety.
At Elite Automotive Finishes, we always prioritize quality, and whenever possible, that means choosing OEM parts. But what’s the difference—and why does it matter?
Let’s break it down.
What Are OEM Parts?
OEM stands for Original Equipment Manufacturer. These are the parts made by or for your vehicle’s manufacturer—the same ones it came with when it rolled off the dealer lot. They’re designed specifically for your vehicle’s make, model, and year, and that makes a big difference.
The benefits of OEM parts include:
Exact fitment — No adjustments needed.
Higher quality materials
Consistency and reliability
Easier installation for technicians

What Are Aftermarket Parts?
Aftermarket parts are made by third-party manufacturers outside of the original automaker’s supply chain. Some are CAPA-certified, which means they’ve been tested and approved to meet specific fit and quality standards. Others are not certified at all.
While some CAPA parts can be close in quality to OEM, non-CAPA parts tend to be a gamble.
Here’s what to expect from aftermarket parts:
More affordable for insurance companies
Inconsistent fit and finish
Variable quality and durability
More risk of delays due to wrong parts or returns
While they may look similar on the surface, they’re often less durable and more difficult to install correctly—which can impact both safety and aesthetics.
Why We Prefer OEM at Elite
We always aim for the highest quality repair possible, which is why we prefer OEM parts. The biggest reason? Fit. OEM parts are engineered to fit your car perfectly. That reduces time in the shop, lowers the chance of error, and ensures a better end result.
But it’s more than just fit. OEM vendors usually have better shipping times, greater part availability (especially for newer vehicles), and much lower odds of sending the wrong item. That kind of reliability matters—both for our team and for you.
When customers search for auto body shops in Mesa AZ or auto body repair Mesa, they’re not just looking for a quick fix. They want a shop that does it right the first time. That’s what we deliver.
Which Option Will My Insurance Cover?
In many cases, insurance companies prefer aftermarket parts because they’re cheaper. However, you may have the option to request OEM parts depending on your policy. We’re happy to work directly with your provider to explore your options and advocate for the best possible repair.
If OEM isn’t approved, we’ll walk you through all available choices—including CAPA-certified alternatives—and be fully transparent about what you can expect.
