Product Details

Bilstein B4 Air Suspension Replacements are replacement suspension modules for vehicles where the air spring and damper are mounted together as a strut. As with their separate B3 Air Spring range, the air-bags need to perform exactly the same as the originals in order for your vehicle to ride and handle correctly. Because the shock absorber is attached to the air spring unit, this also needs to be valved the same as the original units to work correctly with the air spring. Bilstein have integrated one of their industry benchmark B4 shock absorbers into the strut.

For vehicles where the air spring is mounted onto the shock absorber in a strut arrangement, Bilstein offer B4 air spring strut modules.

These feature an air spring designed to work correctly with the vehicles factory fit air suspension system. Modern air suspension systems use sensors and sophisticated electronics to adapt very rapidly to changing road conditions. This means that the air bags used need to be able to both hold constant air pressure, and rapidly inflate or deflate. Using an air spring that didn't work as intended would compromise the vehicles ability to soak up bumps.

Because the air spring is mounted onto the shock absorber in a strut arrangement you need a shock absorber that will work perfectly in concert with the air spring to the same specifications as the original unit.

Bilstein's B4 dampers are the perfect choice. Bilstein are original spec on many European and Japanese cars and their B4 range is designed to be a direct replacement for factory equipment.

Please note - these are replacements units for vehicles that came with air suspension as standard. They are not a conversion for vehicles supplied without.
