Windshield Replacement – The Difference Between Dot Certified (oem Glass) And Aftermarket Glass
Consumers looking for a high-quality windshield replacement should understand the major differences between the various types of auto glass available to them. Common options include original equipment manufacturer (OEM) distributor glass, dealer glass, and aftermarket glass. Which is the best for your windshield replacement?
If you purchase a replacement from a manufacturer-authorized dealer, you will get the same brand as your original windshield. But if you purchase your window from an auto glass shop, you will get it from a reliable OEM distributor who manufactures windows to the same exact specifications. These windows are the same shape, size, thickness, durability and color as original specifications. They are practically identical to the dealer versions and are also DOT-certified, meaning they are approved by the Department of Transportation.
Since this windshield was not manufactured by the original company, it is not exactly the same as what the dealer had on the car when it was manufactured, but it is comparable. The similarity is enough that if you were to return a leased automobile with an OEM replacement, the dealer would accept it.
