Help protect the polished piston rod on your front struts with the SACHS Suspension Strut Bellows / Bumper Bellows, part number 900132. This front service kit is listed under both names. It is an exact-fit replacement for the 2001-2006 BMW 325I, 2007-2013 BMW 335I, 2003-2008 BMW Z4 and the other BMW applications listed below.
The bellows covers the exposed piston rod so road contaminants have a harder time reaching the rod and seal. A torn, cracked, collapsed or missing bellows is a sign it may need replacing. If a worn bellows has let debris reach the rod, the strut itself may also need attention, so have it inspected.
Fitment (front):
See the Buyer's Guide tab for engine details.
What does the SACHS 900132 strut bellows / bumper bellows do?
It helps safeguard the strut's highly polished piston rod and low-friction seal from environmental elements. It also helps cushion the suspension in harsh driving conditions.
Should I replace the bellows when I install a new strut?
Yes. SACHS suggests replacing the bumper bellows with each new shock and strut, so the new unit's rod and seal get fresh protection.

What are signs my strut bellows may need replacing?
A torn, cracked, collapsed or missing bellows, or dirt on the exposed strut rod, are signs it may need replacing. Have the strut inspected to confirm its condition.
