Bilstein 23-303928: OE-Compatible B6 DampTronic Upgrade for Your 911
The Bilstein 23-303928 B6 Performance (DampTronic) front monotube shock is a direct performance upgrade for 2020-2025 Porsche 911 models equipped with factory electronic damping control (PASM). Designed to pair with your factory springs, this shock retains all active PASM features and factory controls while delivering application-specific valving that sharpens handling response beyond the factory damper, without disabling any electronic suspension functions.
Key Features
- Direct OE-fit replacement for factory PASM-equipped front dampers
- Retains full compatibility with factory electronic damping control (DampTronic/PASM)
- Application-specific valve tuning for improved handling over stock dampers
- Monotube gas-pressure shock design for consistent damping under hard use
- Rigorously tested to meet or exceed OE quality standards
- Designed to be paired with OE factory springs
