What's An INFINITI Rear Side Member Extension?

What's An INFINITI Rear Side Member Extension?

When it comes to repair information, vehicle makers use a wide variety of terminology for replacement parts. All of the different names can be confusing, especially when repairing a variety of vehicle makes and models.

When searching for repair procedures, knowing what to look for can save valuable time. When searching INFINITI, for example, instead of looking for a lower rail, look for the front side member. (See Table 1) Having the correct repair information is essential to a proper repair process. Without vehicle maker repair information, you are potentially re-engineering the vehicle without the research into how the vehicle would react in another collision.
