Detailed Description

This Bilstein suspension strut assembly is part of the B4 OE Replacement (DampTronic) line, engineered for drivers who want to restore factory ride characteristics without changing the vehicle’s original suspension behavior. The twintube design, fixed spring seat, and base cup lower mount support consistent operation in electronically controlled systems.

For Porsche 718 Boxster and Porsche 718 Cayman rear suspension, as well as Boxster and Cayman rear applications, this series is built to match the original system requirements and preserve the intended driving feel. If you are replacing a worn rear strut assembly on a Porsche with PASM, 23-275614 provides a direct-fit solution.
