Detailed Description

Rein AVZ0158P is a rear jounce bumper for suspension systems that require an OE-quality replacement part. By matching the original bump stop design and rubber hardness, this part helps preserve the intended suspension stop point and supports quieter, more controlled operation over rough roads. It is a direct-fit style solution for standard-suspension Audi and Volkswagen platforms, including Audi A4, Audi A4 Quattro, Audi A6, Audi A6 Quattro, Audi S4, and Volkswagen Passat models.

Rein AVZ0158P is a practical choice when replacing worn rear bump stops on 1998-2005 Volkswagen Passat and 1998-2005 Audi applications listed in the fitment data. The part number AVZ0158P is also useful when searching for an OE-style rear suspension bump stop for these vehicles.

What It Helps Address

Degraded ride quality caused by aged rubber components
Uneven suspension response after bump stop wear
