Product Details

Bilstein B8 Performance Plus dampers are engineered as an upgrade over original equipment dampers when the vehicle uses lowering springs. On the Porsche 911, this front strut cartridge uses a monotube construction and model-specific valving to support sharper handling and more controlled suspension movement. The B8 Performance Plus line is aimed at drivers who want a firmer, more responsive setup without moving away from Bilstein’s OE-level quality standards. Part number 34-001134 is a direct fit for 1965-1989 Porsche 911 front applications with an inner threaded strut tube.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excessive body roll after lowering the suspension
• Soft or delayed damping response from worn OE struts
• Reduced front-end control during cornering and braking
• Uneven ride feel caused by aging suspension components
• Loss of precision in a Porsche 911 lowered-spring setup

Installation Notes

Verify that the vehicle has an inner threaded strut tube before ordering. This front strut cartridge is intended for use with aftermarket lowering springs and should be matched to the correct Porsche 911 front suspension configuration. Confirm all fitment details against the vehicle and existing strut housing before installation.

Quality Assurance

Bilstein tests B8 Performance Plus dampers to standards that meet or exceed OE requirements. The monotube design and application-specific valving are part of Bilstein’s performance-oriented suspension engineering for the Porsche 911 platform. Part number 34-001134 is built for consistent fitment and controlled damping performance in lowered front suspension applications.
