This Bilstein B8 Performance Plus front strut is a 36mm monotube assembly for the front axle of a 2006 Volkswagen Passat 2.0T. The manufacturer describes the B8 as the B6 damper with a specially shortened design, which keeps the spring preload correct when a lowering spring is installed. That shortened body is the reason to choose it over a stock-height replacement: it is meant for a lowered front end, and a stock-height strut will not give the same result behind lowering springs. Owners on user forums report that Bilstein struts paired with aftermarket lowering springs feel more planted than the same springs on factory dampers. Fitment year ranges vary between sources, so confirm the 2006 Passat 2.0T application with the manufacturer before ordering. Replacing a front strut on this FWD platform is a moderate job; owners on user forums say it takes roughly 2 to 5 hours, mostly because of steering knuckle removal. Long-tail searches this part serves include lowered Passat 2.0T front struts, B8 Performance Plus lowering spring upgrade, and 35-122081 front strut replacement.
The manufacturer positions the B8 for vehicles fitted with lowering springs or a sport suspension, so it is not the intended choice for an unmodified ride height. Confirm with the manufacturer before installing it with factory springs.
Owners on user forums report that Bilstein's lifetime warranty covers defects but not normal wear, and that a rebuild service is available.
Owners on user forums list metric sockets from 10mm to 18mm, a strut spring compressor, and a strut spreader. They also warn that factory struts may have a retaining clip that holds the assembly until the bolts are removed.
Owners on user forums rate this as moderate with a pneumatic impact wrench and semi-difficult without one, and estimate 2 to 5 hours depending on tools and corrosion. Plan to remove the steering knuckle, or lower the strut carefully with the knuckle in place. Mark the sway bar endlink, ABS sensor wire, and brake line clips, and keep the brake hose free of strain. Some owners on user forums lift the knuckle clear with a length of lumber bolted to the sway bar bracket, which avoids disconnecting the axle. Expect the upper strut mount to need Torx or Allen bits along with 21 to 22mm sockets, and keep the front fender paint protected while working.
