What Are OEM Parts?
OEM parts, or Original Equipment Manufacturer parts, are components made by the original maker of your vehicle. These parts are identical to the ones your car was built with at the factory—ensuring an exact fit, optimal performance, and long-term reliability.
When your vehicle is involved in a collision or needs body repair, using OEM parts ensures that the quality and safety of your car are preserved. OEM parts are designed specifically for your make and model, unlike aftermarket parts which may be more generic and vary in quality.
Whether you’re repairing structural components or replacing a bumper, choosing OEM parts minimizes the risk of improper installation or future mechanical issues. OEM body parts help maintain your vehicle’s warranty and resale value.
- Guaranteed compatibility with your specific vehicle model
- Consistent quality and engineering standards
- Preserves original safety features and crash performance

Why OEM Parts Matter in Auto Body Repairs
Using OEM parts in body repairs is essential for maintaining your vehicle’s original integrity, safety features, and performance. These parts are manufactured to meet the exact specifications set by the original automaker, unlike aftermarket alternatives which may not offer the same fit or function.
For critical areas like crash zones, bumpers, and structural components, OEM parts help ensure that your vehicle will perform as expected in future collisions. This can be a major factor in preserving both your personal safety and your car’s resale value.
After an accident, many repair shops or insurers may suggest aftermarket parts to cut costs. However, this could result in inconsistent materials, fitment problems, or even reduced safety compliance.
- OEM parts support factory-grade collision performance
- Maintain vehicle warranty and manufacturer standards
- Ensure precise alignment and proper part installation
- Preserve resale value with documented quality repairs
According to the Consumer Reports guide to crash parts, OEM parts are often worth the investment, especially when safety and long-term durability are top priorities.
OEM vs Aftermarket Parts: Key Differences
When it comes to auto body repair parts, one of the most common decisions is whether to choose OEM or aftermarket parts. Each has its pros and cons, but understanding the key differences can help you make the best choice for your vehicle.
OEM Parts
- Manufactured by the original automaker or a licensed supplier
- Guaranteed fit, quality, and performance
- Typically more expensive but offer peace of mind
- Often required to maintain manufacturer warranty
Aftermarket Parts
- Produced by third-party manufacturers
- May vary in quality, material, and fit
- Generally less expensive than OEM parts
- Can sometimes enhance performance (in performance parts), but not ideal for body repair
While aftermarket parts may save you money upfront, they don’t always meet the standards required for collision safety and long-term dependability. This is especially important for critical systems like airbag sensors, crumple zones, or alignment-dependent components.

How Insurance Companies Handle OEM Parts
After an accident, many vehicle owners are surprised to learn that their insurance policy may not automatically cover OEM parts in body repairs. Insurance companies often default to aftermarket or recycled parts to lower claim costs—unless your policy specifically includes OEM part coverage.
Some insurers offer optional add-ons that guarantee the use of OEM parts in collision repairs. These are typically called OEM endorsements or OEM parts riders, and they can make a major difference in the quality and value of the repair.
It’s important to review your policy details or speak directly with your provider to understand what is and isn’t covered. In many cases, you have the right to request OEM parts, but you may need to pay the difference out of pocket.
- Many standard insurance policies favor aftermarket parts by default
- OEM parts endorsements can be added for additional peace of mind
- State laws vary on whether you must be notified before non-OEM parts are used
- Some luxury or newer vehicles may qualify for OEM part use automatically

Top Benefits of Using OEM Parts
Choosing OEM parts for auto body repairs offers a wide range of advantages that go beyond just appearance. Whether you’re restoring your vehicle after a collision or replacing worn-out components, OEM parts deliver unmatched value in terms of fit, safety, and performance.
1. Exact Fit and Compatibility
OEM parts are engineered by the original manufacturer to precisely match your vehicle’s specifications. This ensures perfect alignment, proper installation, and consistent operation—especially important for complex systems like bumper sensors, airbags, or structural panels.
2. Maintains Vehicle Safety Standards
OEM parts help your vehicle perform as it was originally designed to in crash scenarios. This preserves the built-in safety features, crumple zones, and airbag timing that aftermarket parts might not support.
3. Retains Warranty Protection
In many cases, using aftermarket parts can void your vehicle’s manufacturer warranty. OEM parts maintain compliance with warranty terms, which is critical for newer or leased vehicles.
4. Higher Resale Value
Repair documentation showing the use of OEM parts can positively influence your car’s resale or trade-in value. Buyers are more likely to trust repairs made with manufacturer-grade components.
5. Consistent Quality and Durability
OEM parts go through rigorous testing and meet strict quality control standards. With aftermarket parts, consistency can vary significantly between suppliers.

Choosing a Body Shop That Uses OEM Parts
Not all repair facilities prioritize OEM parts in body repairs, so selecting the right body shop is crucial. Look for certified or manufacturer-approved collision centers that follow strict OEM repair guidelines and use genuine replacement components.
Shops that are part of programs like OEM Collision Repair Networks or carry certifications from automakers (e.g., Ford Certified, Honda ProFirst, or Toyota Certified Collision Centers) are more likely to use OEM parts and processes that meet factory standards.
Tips for Finding the Right Shop:
- Ask directly if they use OEM parts and can provide documentation
- Look for I-CAR Gold Class or ASE certifications
- Check online reviews for mentions of quality and transparency
- Request a written estimate that clearly lists OEM components
- Confirm they can work with your insurance provider on OEM part approvals
A quality shop will be transparent about the parts used and willing to work with your insurer to honor OEM endorsements or rider policies.
