OEM crash parts come from the carmaker, aftermarket parts come from other manufacturers and used parts come from salvaged vehicles. California's Auto Body Repair Consumer Bill of Rights says you have the right to be informed about which type is used on your car.
Key takeaways
- You have a right to know the parts type.
- OEM costs more but offers the most predictable fit.
- Aftermarket parts vary in quality, so ask about certification.
The three types
New OEM (original equipment manufacturer) parts are made by or for the carmaker. Aftermarket crash parts are new parts from other manufacturers. Used parts come from salvage yards and may be original or aftermarket. All three can be used in collision repair, and your policy may specify which.
Fit and finish
OEM parts usually fit with the narrowest tolerances, which shows in gaps and alignment. Aftermarket parts range from excellent to poor, and certified parts are tested for fit and material. Used parts keep factory fit but carry wear from their first life.
What your policy says
Many policies allow aftermarket or used parts to keep costs down. Some policies, or leased cars, require OEM. Check your coverage. If you want OEM and your policy does not require it, you may pay the difference.
Safety-critical parts
Bumper reinforcements, crumple zones and structural pieces affect crash performance. Ask whether the replacement part has matching specifications and how it will be attached. The repair procedure from the manufacturer is the reference point.
Questions to ask your shop
Ask which parts are on the estimate, whether they are certified, what the warranty covers and whether the part type affects paint or fit. A transparent shop shows you part numbers and sources on request.

Frequently asked questions
Do I have to accept aftermarket parts?
Your policy may allow them. Ask your insurer and shop, and review the Consumer Bill of Rights.
Are used parts safe?
Used OEM parts can be fine if they come from undamaged vehicles and are inspected. Structural parts need more scrutiny.
Does part type affect warranty?
It can. Ask the shop what the workmanship warranty covers and who backs the part.
Can I request OEM?
Yes, though you may pay the difference if your policy does not cover it.
