A vehicle suspension control system includes a central suspension spring core, a first suspension spring surrounding an upper portion of the central suspension spring core, a second suspension spring surrounding a lower portion of the central suspension spring core, the first suspension spring and the second suspension spring coupled between a wheel and a fixed structure of a vehicle to inhibit movement of the wheel, a spring seat surrounding the central suspension spring core and coupled between the first and second suspension springs, the spring seat including an outer sleeve and multiple seals for retaining magnetorheological fluid between the outer sleeve and the central suspension spring core, one or more electromagnets adjacent the spring seat, and a suspension control module configured to energize the one or more electromagnets to selectively modify a viscosity of the magnetorheological fluid to inhibit movement of the first suspension spring or the second suspension spring.
