Bilstein B8 Rear Strut for Porsche Boxster

The Bilstein B8 Performance Plus rear strut assembly is built for the 1997-2004 Porsche Boxster with aftermarket lowering springs. Part number 22-046246 uses application-specific valving and a twin-tube internal design to sharpen handling response while maintaining OE-level quality control.

Finished in yellow paint, this rear suspension strut assembly is a direct-fit performance upgrade for drivers looking to improve control and reduce excess body movement on a lowered Porsche Boxster. Bilstein 22-046246 is engineered for the rear position and pairs with lowering springs for a more planted stance and more precise road feel.

Product Details

The B8 Performance Plus line is Bilstein’s performance-oriented damper range for vehicles using lowering springs. For the Porsche Boxster, part number 22-046246 is tuned for the rear suspension to help restore proper damping control after ride height changes. This setup supports more consistent handling response, especially in applications where the factory strut is no longer matched to the spring rate or lowered geometry.

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

Common Issues This Part Can Address

• Excessive rear-end bounce after installing lowering springs
• Reduced damping control from worn OE rear struts
• Loose or unsettled handling in a lowered Porsche Boxster
• Uneven ride response over bumps and transitions
• Loss of suspension control during cornering and braking

Installation Notes and Tips

Install 22-046246 at the rear position only on compatible Porsche Boxster models. Because this strut is intended for lowered spring applications, verify spring and ride-height setup before installation. Inspect related suspension components such as mounts, bushings, and hardware condition during service, and follow factory torque specifications and alignment procedures after installation.

Quality Assurance

Bilstein tests B8 Performance Plus dampers to meet or exceed OE standards, with quality control focused on consistent performance and durability. The 22-046246 rear strut assembly reflects Bilstein’s performance damper engineering for lowered Porsche Boxster suspension setups.
