Bilstein B1 Sway Bar Adapter Kit for Porsche 911 (991) with Active Front Stabilizer Bar
The Bilstein B1 Sway Bar Adapter Kit is a critical supporting component designed for Porsche 911 (991 generation) models equipped with the factory active front stabilizer bar.
When installing lowering springs or coilover systems (such as Bilstein B16 Clubsport kits), this adapter kit ensures proper clearance and geometry by limiting the lowering range to the minimum specification. Without this adapter, vehicles with active sway bars can experience clearance issues or improper suspension geometry when lowered.
Bilstein engineered this B1 component to work seamlessly with their performance suspension systems while maintaining the functionality of the factory active stabilizer system.
Key Features
- Designed for Active Stabilizer Bar Vehicles – Specifically for Porsche 911 models with factory active front sway bar
- Limits Lowering Range – Prevents excessive lowering that could cause clearance or geometry issues
- OEM Quality Construction – Galvanized finish and built to Bilstein’s high standards
- Direct Fitment – No modifications required when used with compatible Bilstein kits
- Essential for Clubsport / B16 Kits – Recommended when installing performance lowering components
