OEM v. Aftermarket Parts -The Real Truth

Depending on the auto body shop you choose, you may have a choice between OEM and aftermarket parts for your repairs. If you’ve never had this type of repair done on your vehicle, you might be wondering if there’s really a difference between the two. Is one better than the other? Here’s a look at how these parts differ and how you can make the best decision for your vehicle.

How Are OEM and Aftermarket Parts Different?

OEM stands for “original equipment manufacturer.” These parts are made by your vehicle’s manufacturer, so they are specifically designed for your make and model. They fit perfectly and are of the exact same quality as the parts installed in your vehicle when it was in the factory. However, OEM parts are more expensive than aftermarket parts.

Aftermarket parts are made by other manufacturers—not automakers. These parts are often designed to fit more than one kind of vehicle, which means they may not be an exact fit. In some cases, parts may even need to be modified to fit properly. Since aftermarket parts are often more of a “universal,” part, they tend to be cheaper in quality and price.

OEM or Aftermarket: Which Should I Choose?

Although some aftermarket parts may be acceptable for auto body repairs, others may not be. This is because there’s often a lot of variation in the quality of aftermarket parts. For example, many of them don’t have the same level of rustproofing as an OEM part. The fit or finish may not match your vehicle, or the panels may not align properly.

With OEM parts, everything looks, fits, and functions exactly like the original factory parts that came with your vehicle. Unlike many aftermarket parts, OEM parts are crash-tested, and most are backed with a one-year warranty.

Another factor to consider is ADAS (Advanced Driver Assistance System) safety features. This is a series of electronic systems that use sensors and cameras to assist drivers and increase vehicle safety, like lane departure warning, blind-spot detection, and forward-collision warning. Many of these sensors and cameras are located in areas that often suffer collision damage, like the front and rear bumpers. OEM parts are made to fit your specific vehicle and support the functionality of ADAS, unlike aftermarket parts. An ill-fitting part could potentially block a sensor or cause other issues that prevent ADAS from working as it should.

Since aftermarket parts are less expensive than OEM, many insurance companies will push for drivers and shops to use them. Sometimes insurance companies will insist drivers use “preferred shops” that use only lower-cost parts so they can save money on the claim. Regardless of whether you want OEM or aftermarket parts, you have the right in California to take your vehicle to any shop you like. If you’re set on OEM parts for your repair, you also have the right to ask to pay for the difference.

Depending on the shop and the age of your vehicle, you may also have the option of used parts. These typically come from a salvage yard and can be significantly cheaper than OEM or aftermarket parts. However, since they’re used, they may come with wear and tear. If you decide to go with this option, make sure the parts have been inspected and warrantied.

Ultimately, the decision between OEM, aftermarket, or used parts will depend on a few factors: your budget, the shop you choose, and the level of quality you’re looking for in a repair.
