FCS 99006 Electronic Air Suspension Strut Assembly

The FCS 99006 is a direct-replacement electronic air suspension strut assembly engineered to restore factory ride quality and handling on equipped Audi vehicles. Designed as a fully assembled, ready-to-install unit, this strut integrates the air spring, damper, and electronic control interface into a single component that matches the OE configuration precisely.

FCS Auto is a vertically integrated manufacturer with over 60 full-time engineers dedicated to ensuring every part meets or exceeds original equipment quality standards. The 99006 is built to deliver the same adaptive damping response and ride height control expected from the factory system.

Key Features:

• Electronic air suspension design — integrates with the vehicle's electronic suspension control module for adaptive damping
• OE-matched air spring — maintains factory ride height and load-carrying capacity
• Freudenberg NOK seals — premium seals for long service life and reliable air retention
• Mirror-finished, hard-chrome piston rod — resists corrosion and wear for consistent dampening performance
• Nitrogen gas charged — reduces fluid aeration and strut fade for stable, consistent handling
• Precisely calibrated valving — individualized to simulate OE ride and feel for the specific application
• Complete assembly — no need to compress springs or source individual components; installs with standard tools
• Engineered to meet and exceed OE specifications — validated by FCS's state-of-the-art quality control processes

As a complete strut assembly, the FCS 99006 eliminates the complexity of disassembling worn components and removes the safety risk of compressing coil springs. On vehicles equipped with Advanced Driver Assistance Systems (ADAS), proper ride height restoration is especially important, as suspension geometry directly affects camera and sensor calibration.
