The Air House 2 Aero Sport from Universal Air Suspension is a single convoluted air spring that features a hollow tube that passes through the center of it. This allows you to mount the bag on your existing coilover strut bodies, hence the term bag-over-coil. The Air House 2 Aero Sport is designed for specific applications where driving as low as possible at a stiff spring rate is essential. In most cases, people go with the standard Aero Sports
for cars since the Air House 2 Aero Sports lack lift and don’t feature any benefits other than increased spring rate.
