The BWI McPherson Strut Suspension Module was born from a challenging customer requirement requesting an air spring module with side load compensation. This was successfully performed for the first time in the automotive industry on the 1999.
Range Rover and still used today on this same platform. The design was made to survive extreme off-road conditions while still being an integral component of the most comfortable air suspension on road.
Designed in a modular way, the BWI air suspension modules minimize the number of custom components and maximise commonality between the front and rear. The modules are designed in Europe and made from three main sub assemblies; the top mount, the air spring and the damper.
The Top Mount can integrate the suspension bearing when required for a McPherson strut construction.
It is designed to be air tight for the life of the vehicle.
BWI has experience with most available air spring technologies:
BWI air spring suspension modules are available with possible damper configurations from the largest 28mm Ø damper rod twintube McPherson strut to the multidisc high-pressure monotube. The air spring suspension module can be combined with BWI’s new MagneRide magnetorheologic fluid damper with the objective of incorporating all the best features of BWI’s air suspension with advanced controlled damping.
The unit is supplied fully assembled and 100% tested for air leak. Low leak rates ensure vehicle ride height stability even during long parking periods.
