OEM vs Aftermarket Parts


It’s a question as old as the first vehicle repair shops: OEM or aftermarket parts? While both have benefits, one is definitely a clear winner. Here’s what you need to know about the difference between OEM parts and aftermarket parts. OEM parts are parts that come directly from the vehicle’s manufacturer. The benefit to this is that you can be assured that it is the right part for your particular make and model of vehicle, and there’s usually a warranty involved. There’s also a better assurance of quality as OEM parts are obtained directly from the manufacturer or considered a certified likeness of the original part. The downside? OEM parts are usually a little more expensive than aftermarket parts.


Unlike OEM parts, aftermarket parts are not manufactured or guaranteed by the car manufacturer. In some cases, this is a good thing because they can be less expensive to purchase and they don’t need to be purchased from a dealership parts counter. They are also easier to obtain, as just about every auto parts store in town offers aftermarket parts. The downside is they aren’t always made from quality materials and using them might cause further damage to your vehicle.

The Benefits Of OEM Parts

When it comes to replacement parts for your vehicle, the clear winner is OEM parts. Simply put, the peace of mind you enjoy with OEM parts far outweighs the additional cost. While you might be tempted to just go with a less expensive aftermarket part from your local store, it is always better in the long run to utilize a certified dealership and genuine OEM parts for your Buick or GMC. After all, you really do get what you pay for.
