Utilizing Bilstein’s monotube shock absorber design for heat dissipation
and ride control, the PSS9 Coilover System for the Audi S4 (B5) adds a matched performance
spring and threaded ride height adjuster to provide a complete
suspension system for a vehicle.
The fully adjustable monotube gas shock absorbers offer nine precise
compression and rebound settings, from comfort to competition. The front
and rear progressive rate springs allow for the accurate adjustment of a
vehicle's ride height, stance, cornering balance and ride quality to
Ride Comfort and Performance Without Compromise
The piston head design allows independent tuning of the compression and
rebound damping forces to provide optimum ride comfort and performance
without compromise. It features fewer parts than most conventional
designs. The product's simple, yet exceptionally functional digressive
design contributes to the extreme durability and long life of Bilstein
About the Bilstein Shocks Included in this System
All Bilstein gas pressure struts/inserts and gas pressure shock
absorbers operate on the same principle. They are manufactured with the
rod pointing down into the strut tube, thereby utilizing the thicker,
stouter body portion of the shock absorber to dissipate side loads.
Consequently, due to the increased diameter and surface of the pressure
tube, the Bilstein gas pressure strut/insert or shock is better suited
to take increased side loads when compared with the conventional
Additional advantages, based on development strongly influenced by the
motorsport industry, include greater stability, better road handling,
and accurate steering. This combined with extremely high quality
manufacturing and materials, means Bilsteins will last approximately
four times as long as Original Equipment.
