Performance shock absorber for lowering springs

Bilstein B8 Performance Plus shock absorber, part number 24-348201, is built as a performance upgrade for vehicles using aftermarket lowering springs. It uses application-specific valving and a monotube design to sharpen handling response while maintaining OE-level quality standards.

Key features

  • Monotube internal design for consistent damping response.
  • Application-specific valve settings for tuned handling performance.
  • Yellow painted finish from the B8 Performance Plus series.
  • Built for use with aftermarket lowering springs.
  • Tested to meet or exceed OE quality standards.

Detailed fitment and application

Compatible with 2003-2008 BMW Z4 rear applications. This Bilstein shock absorber is a strong match for BMW Z4 owners looking to improve control and achieve a lower stance without changing the character of the suspension system. The B8 Performance Plus line is aimed at drivers who want firmer response and more precise damping from a suspension shock absorber, and part number 24-348201 is engineered around that use case.

This part cross-references Bilstein (e.g., 24-104937) for the same application.

What it is used for

  • Excessive body movement after lowering the suspension.
  • Soft or inconsistent damping response.
  • Reduced handling precision in spirited driving.
  • Loss of control feel when paired with shorter springs.

Installation notes and tips

Verify collapsed and extended length before installation: 15.16 in. collapsed and 22.50 in. extended. The shock uses an eye 12 mm lower mount and stem upper mount. Boot and spring seat are not included, so reuse or source those components as needed for the application. Confirm rear fitment on the BMW Z4 before ordering.

Quality assurance

Bilstein states that each damper is rigorously tested to meet or exceed OE standards. The B8 Performance Plus series is part of Bilstein's tuning-focused suspension lineup, and part number 24-348201 reflects that application-specific engineering approach.
