Quick facts

Part: KYB KG9307 suspension strut assembly
Fits: the 1985-1989 BMW 635CSi and other vehicles
Position: Rear
Condition: New

Fluid leaking from the strut body, a bouncy ride or a clunk over bumps can mean a strut is worn. These signs alone do not prove the strut is the problem, since a worn tire can cause a similar shake.

Fits

Besides the 1985-1989 BMW 635CSi, this strut fits the 1982-1988 BMW 528e and the 1985-1988 BMW 535i. Driving a different BMW? Look up your year and model in the "Vehicles it fits" section. Plan on two struts per car, one on each side of the rear axle, and fit them together.
