ABSTRACT:
A suspension system for a vehicle includes a plurality of spring assemblies, each spring assembly including, in combination, a coil spring and an air spring arranged around a common central axis, and being mounted above the rear axle of the vehicle. A method for improving a vehicle's ride, handling, and load-carrying capability includes providing the foregoing suspension system for which respective coil springs are positioned within respective housings; partially inflating respective air springs thereby causing respective coil springs to partially collapse into their housings when improvement to the ride is desired in combination with improvement in load-carrying ability; and completely inflating respective air springs thereby causing respective coil springs of the plurality of spring assemblies to substantially completely collapse into their housings when maximum load-carrying ability is desired.
