Bilstein 19-103112 Rear Damper for BMW 3 Series E46 Touring and Compact
Refresh the back end of your E46 with a genuine Bilstein solution that brings your BMW’s ride and handling back to factory sharpness. The Bilstein 19-103112 is a gas-charged, twin tube rear shock unit built to original equipment standards for the 3 Series E46 estate and Compact hatchback. Expect tight body control, improved composure over bumps and that planted BMW feel on British roads.
Ideal for owners wanting OEM-level comfort, predictable grip and dependable road manners without harshness. We run these on our own E46 builds and our customers consistently report a night-and-day difference in stability, steering confidence and overall ride quality.
