Roadactive Suspension
Roadactive Suspension
RoadActive Suspension (RAS) manufactures and distributes an easy-to-install tension coil spring that attach to the rear leaf springs of any pickup truck or van. RAS works to strengthen the existing leaf spring by engaging proportionate to force applied, converting the traditional "passive" spring into a more desirable mechanical "active" suspension system. Experience squat, bounce or instability from a heavy load? RAS will improve the way your truck handles that load, while providing unparalleled ride quality at all times.
Improve load handling, ride quality, and stability with your vehicle by adding a Roadactive Suspension to your truck or van. The Roadactive Suspension consists of a set of two very powerful, variable rated coil tension springs that assist the rear leaf springs by holding them in their original bowed position. When a strain is applied to the leaf springs from a load or vehicle weight shift, the RAS comes into action to immediately absorb the force of the load. The greater the strain, the more corrective counter assistance force is applied from the RAS unit. On cornering, RAS reduces body roll by supporting the springs which are taking the increased load. By not allowing these springs to flatten out, the vehicle corners more level with greater contact of all four tires to the road. Improved traction translates to better control and handling.
