Car insurance glossary
What is aftermarket parts?
Aftermarket parts are replacement vehicle parts made by a company other than the original vehicle manufacturer.
Also called: non-OEM parts
Glossary date: July 27, 2026
How it works
They may be new and designed for the same application as an OEM part. Policy provisions, state rules, certification, and availability influence their use in repairs.
Example
A body shop estimate lists a new replacement fender made by an independent parts manufacturer.
Why it matters
The label alone does not describe the part's certification, warranty, fit, or repair suitability.
What to check on your policy
Ask who made the part, whether it is certified, what warranty applies, and how to raise a fit or quality concern.
