Help shield your rear strut's polished piston rod from road grit and grime with the SACHS Strut Bellow 900122. This exact-fit service kit is listed for the rear suspension of several BMW models, among them the 2001-2003 BMW 525i, 2001-2003 BMW 530i and 1997-2003 BMW 540i. See the Buyer's Guide tab for the full list and engine details.
The strut bellow covers the exposed section of the piston rod as the strut moves through its travel. When the bellow splits, tears or goes missing, dirt and other environmental elements can reach the rod and the strut's seal. Installing a fresh bellow alongside a new strut helps protect the new unit's rod and seal.
Signs this part may need replacing: a cracked, torn or missing bellow, or dirt and grime building up on the exposed piston rod.
What does the SACHS 900122 strut bellow do?
It covers the strut's highly polished piston rod and low-friction seal to help protect them from environmental elements. It is also designed to help cushion harsh driving conditions.
