Bilstein B8 Front Right Strut

The Bilstein B8 Performance Plus strut assembly is built for drivers upgrading a lowered suspension on a 2003-2008 BMW Z4. This front right damper uses a monotube design and application-specific valving to sharpen handling response while maintaining OE-level quality standards.

Key Features

• Bilstein B8 Performance Plus series for lowered-spring applications
• Front right suspension strut assembly for 2003-2008 BMW Z4
• Monotube internal design for consistent damping control
• Blue bellows boot included
• Yellow painted finish
• Stem upper mount type with special lower mount type

Performance Line Details

Bilstein B8 Performance Plus dampers are part of Bilstein’s performance-focused line for vehicles running aftermarket lowering springs. The valving is tuned for the application, helping the suspension work with reduced ride height and supporting more precise road feel. This part number, 35-124122, is engineered for the front right position on the BMW Z4 and is a direct match for the listed fitment.

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

What It Helps Address

• Excessive body movement after lowering the suspension
• Reduced damping control from worn OE struts
• Loose or unsettled front-end handling
• Mismatch between lowering springs and standard dampers
• Uneven ride quality at the front right corner

Installation Notes

Fits 2003-2008 BMW Z4, front right. Verify spring, mount, and position details before installation. This Bilstein shock absorber uses a stem upper mount and a special lower mount type, so confirm the vehicle’s original hardware and suspension configuration match the application. Part number 35-124122 should be matched to the front right corner only.

Quality Assurance

Bilstein tests B8 Performance Plus dampers to meet or exceed OE standards for quality and consistency. The monotube construction and application-specific tuning are designed to deliver controlled performance for lowered BMW Z4 suspension setups.
