Bilstein B8 Performance Plus Rear Shock Absorber (Damper) for BMW 3 Series E46 1998-2006 - M-Technology - Direct-Fit OE Upgrade - Sold Individually

Rear sports shock for BMW 3 Series E46 1998 to 2006

Give your E46 the rear-end control it deserves. This Bilstein B8 unit is a high-performance gas-charged rear shocker designed for BMW 3 Series models with the factory sport chassis package. It is a bolt-on replacement that keeps daily comfort while delivering serious handling precision on fast road and track.

Built with a shortened stroke and application-specific, German-engineered valving, the B8 works brilliantly on cars running sport springs or a lowered ride height. Expect tighter body control, confident traction out of bends and a more composed rear axle over bumpy B-roads. It drops straight into the original mounting points for an easy upgrade over tired standard parts.

• Uprated rear shock for BMW E46 with sport suspension specification
• Gas-pressurised single-tube design for crisp response and consistent performance
• Optimised for cars on shorter springs and lowering kits
• OEM-style fitment with factory hardware compatibility
• Durable, high-quality construction made to last
• Supplied as one rear unit. Order two if you want to refresh both sides

Real-world results

We run B8 setups on customer E46 builds and on our own cars. Feedback has been excellent. Sharper turn-in, better rear stability under power and braking, and a more planted feel without the harshness you get from cheaper shock absorbers. If you are pairing with sport or drop springs, this is a proven combo for fast-road confidence.
