The three categories
OEM (Original Equipment Manufacturer)
Parts produced by or for the vehicle manufacturer — the same parts the vehicle was built with. Typically the most expensive, typically the best fit, and in some cases required by manufacturer repair procedures, particularly for structural and safety-related components.
Aftermarket
Parts produced by third-party manufacturers. Quality varies considerably by part and by producer. Some aftermarket parts are perfectly acceptable for certain applications; others create fit, corrosion-protection or sensor-mounting problems that cost more in labor than they saved in parts.
Recycled / LKQ
Original manufacturer parts salvaged from another vehicle. Often a genuinely good option, especially for older vehicles or non-structural assemblies — provided the part's condition is verified.
Why your estimate may specify aftermarket parts
Insurance estimates are written to a cost. Where a lower-cost alternative part exists, the estimate may specify it. That's a legitimate part of how claims work — but it deserves a conversation rather than a silent substitution.
When we believe a specific part type is necessary for a proper, safe repair, we document why and we make that case to the insurance company. That's part of what advocating for our customer means.
