A multi-axle suspension system for large motor homes, buses and like vehicles provides load dividing, improved vehicle stability and handling, a smoother ride and a driver selectable range of variable braking. The system also maintains an optimum chassis frame height under varying vehicle loading. A tag axle behind the vehicle drive axle includes a trailing arm which rotates upwardly or downwardly in response to an increase or decrease in vehicle loading. Such rotation operates a control linkage of a pressurized fluid control valve to supply additional fluid to or exhaust fluid from a spring device having supportive engagement with the vehicle chassis frame. A constant portion of the vehicle load is maintained on the tag axle at all times.
