Bilstein B4 OE Replacement Rear Air Shock Absorber for 1999-2003 BMW 540i

If your 1999-2003 BMW 540i has started to wallow, crash over expansion joints, or feel vague on the highway, the Bilstein B4 shocks restore the composure it left the factory with.

Bilstein has built suspension in Germany since 1954, and supplies the same engineering to manufacturers as original equipment. The build quality is the reason these outlast what they replace, and they are covered by a limited lifetime warranty.
