When your vehicle goes in for a collision repair, one of the decisions that affects the outcome most directly is which parts are used to complete it. Repair estimates can specify OEM parts, aftermarket parts, or recycled parts, and the differences between them are worth understanding before work begins.
What OEM parts are
OEM stands for original equipment manufacturer. OEM parts are produced by the same manufacturer that made the original components on your vehicle, and they are built to the same specifications. A door panel, bumper cover, or quarter panel replaced with an OEM part is designed to fit your specific vehicle's make, model, and year exactly as the original did.
Because they are manufactured to the same standards as the original components, OEM parts tend to fit precisely, finish consistently with adjacent panels, and perform as intended in a collision.
What aftermarket parts are
Aftermarket parts are produced by third-party manufacturers rather than the original vehicle manufacturer. Quality varies considerably across aftermarket suppliers. Some aftermarket parts are engineered to close tolerances and perform comparably to OEM. Others fit loosely, require adjustment during installation, or finish differently in ways that affect the final appearance of the repair.
The primary advantage of aftermarket parts is cost. They are generally less expensive than OEM, which is part of why insurance estimates often specify them by default. Whether that tradeoff is acceptable depends on the part, the supplier, and where the part is going on the vehicle.
What recycled parts are
Recycled parts, sometimes called salvage parts, are components pulled from other vehicles of the same make and model. They are OEM by origin but have been in service and may carry wear, prior damage, or unknown history.
Recycled parts can be appropriate in certain repair contexts, particularly for components that are difficult to source new or where cost is a significant constraint. Their condition varies, and a reputable shop will inspect them carefully before using them.
How the choice affects your repair
Fit and finish. OEM parts fit to the original specifications of your vehicle. Gaps between panels, alignment with trim and glass, and paint adhesion are all easier to achieve with parts engineered for your specific vehicle. Aftermarket parts that fit imprecisely can result in visible panel gaps or paint that does not match as cleanly.
Safety. Body panels are part of a vehicle's engineered safety system. Crumple zones, mounting points, and structural connections are designed to specific tolerances. Parts that deviate from those tolerances, even slightly, may not perform as intended in a subsequent collision.
Manufacturer warranty. Some vehicle manufacturers specify that repairs using non-OEM parts may affect the terms of an existing warranty. If your vehicle is still under manufacturer warranty, it is worth checking that before authorizing a repair with aftermarket components.
Resale value. Vehicles repaired with OEM parts and carrying a clean, documented repair history tend to hold their value better than those with aftermarket repairs, particularly in private sales where buyers can request vehicle history reports.
What your insurance covers
Insurance estimates default to the lowest-cost option that meets repair requirements, which often means aftermarket parts. Depending on your policy and your vehicle, you may be entitled to OEM parts, particularly on newer vehicles. It is worth reviewing your policy and asking your insurer directly before your repair begins.
At Shur-Way, we use OEM parts on our repairs and are happy to walk you through your options and what your coverage includes before work starts.
Questions to ask before your repair
Does the estimate specify OEM, aftermarket, or recycled parts?
For aftermarket parts, which supplier is being used?
Does your insurance policy entitle you to OEM parts given your vehicle's age or coverage level?
If aftermarket parts are being used, what is the shop's policy if fit or finish issues arise during installation?
