2 BILSTEIN B4 Shock Absorber + Front Axle Bearing for Audi 80 90 Coupe Cabriolet

  
With conventional oil shock absorbers, intensive use can cause the formation of oil foam, which can reduce damping force by up to 35% at higher temperatures. To solve this problem, we developed BILSTEIN gas pressure technology in the 1950s.

With the first series installation of the gas pressure monotube shock absorber at Mercedes-Benz in 1957, we still have a firmly established gas pressure technology in automotive construction today - in monotube and twin-tube versions. This means reliable damping and suspension regardless of the constraints and more safety reserves in all dynamic driving situations. BIL gas pressure shock absorbers.
