Are OEM Ford Serpentine Belts Better Than Aftermarket?

Are you trying to decide between OEM and aftermarket serpentine belts? This comparison guide will help you reach an informed decision. To sum it up, OEM serpentine belts are better than aftermarket belts because they last longer and fit the engine better.

OEM serpentine belts are made with higher quality materials that won't get damaged by the high temperatures in the engine. Also, OEM serpentine belts are better engineered. Many aftermarket serpentine belts are made with lower grade materials, and/or come with a universal design. Many aftermarket serpentine belts won't fit the engine as well as an OEM belt would. Serpentine belts are very important to the operation of the engine. That's why it's not worth taking any risks with an aftermarket belt. You can't go wrong with an OEM one.
