The Roadmaster Active Suspension system is designed to improve the ride, stability, and handling characteristics of any vehicle as well as increasing the load carrying and towing ability when needed to prevent bottoming out. Roadmaster Active Suspension reduces body roll and sway, thus often times eliminating the need for anti sway bars. And, also reduces axle wrap and wheel hop in the same manner as a traction bar. Roadmaster Active Suspension works with your existing leaf springs to strengthen them when needed, unlike airbags, which restrict  the movement of the leaf spring and thus prevent your suspension from working like it was designed to.

Roadmaster Active Suspension systems are available for most all Pickup trucks,  Sport Utility Vehicles, Mini Vans and 15 Passenger Vans with leaf spring rear suspension. Of all the Pickup Truck, Van, or SUV accessories available today, the Roadmaster Active Suspension is the one that you will benefit from more than any other. It is not just an accessory, but a necessity. 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. When towing a boat, trailer, camper or other heavy equipment, Roadmaster Active Suspension adds strength to the rear leaf springs while absorbing the increased load. The resulting stability and reduced sway are felt immediately.

Roadmaster Active Suspension (RAS) overcomes the limitations of passive suspension by introducing mechanically active suspension to the rear leaf springs thereby conquering the traditional three-way load vs handling vs comfort conflict. Once fitted, RAS has the ability to store, dissipate and introduce energy to the system. Being mechanical its action is immediate, unlike hydraulics or air which take time to react. This immediate action is also variable, working in exact counter proportion to force applied, hence the term active. Roadmaster Active Suspension kits consist of a set of two very powerful, variable rated, coil springs designed to support and assist rear leaf springs with up to a one ton carrying capacity.

Once installed, loaded tension from the eye-to-axle mounted coil tension springs hold the leaf springs in their original designed bowed position. When strain from load or vehicle weight shift is applied to the leaf springs, the stabilizers come into action immediately, absorbing the force of the load. Being variable rated, the greater the strain, the more counter-assistance force from the RAS unit. By introducing a powerful ‘load absorbing‘ spring steel coil system to rear leaf springs, RAS greatly assists the carrying capability of the vehicle as stipulated by the manufacturers. RAS absorbs the load that would otherwise cause bottoming out and thereby provides the benefits of a more level and thus safer ride.
