Abstract
A strut assembly includes a damper having a housing and a rod moveable relative to the housing along a longitudinal axis. The strut assembly includes a flexible membrane configured to receive a pressurized gas to form an air spring. A coil spring defines an inner diameter with the housing disposed within the inner diameter to permit relative movement between the coil spring and the housing. The coil spring is at least partially disposed outside the flexible membrane relative to the longitudinal axis.
