OEM vs Aftermarket Parts for Collision Repair — What's the Difference?
OEM vs aftermarket parts — the practical differences in fit, safety and resale value, and the questions to ask before you authorize a collision repair.
What Are OEM Parts?
OEM stands for Original Equipment Manufacturer. OEM parts are made by, or for, your vehicle's manufacturer — the same parts the car was built with.
What Are Aftermarket Parts?
Aftermarket parts are made by other companies to fit a range of vehicles. Quality varies by manufacturer: some are close to OEM, others are not. Recycled (used OEM) parts are a third option.
Why Repair Estimates Include Non-OEM Parts
Aftermarket and recycled parts usually cost less. Many policies allow repairs with parts of "like kind and quality", so an approved estimate may include them. Check your policy wording to see what yours says.
Differences That Can Matter to You
Fit and finish
OEM parts are designed for your specific vehicle. Aftermarket panels can differ in fit, which can show up as uneven gaps or wind noise.
Safety-related parts
For structural and safety-related components, ask the shop how the part has been tested for your vehicle and follow the manufacturer's repair procedures.
Resale and leases
Buyers and dealers may look closely at repair quality. If your vehicle is leased, check the lease agreement — some require OEM parts for repairs.
Questions to Ask Before Authorizing Repairs
Whether you can upgrade to OEM, and who pays the difference, depends on your policy and the approved estimate. Ask your insurer and your repair shop before work starts.
