    Increase Overall Vehicle Stability and Handling Performance

    Roadmaster's Active Suspension System is the only leaf spring support that converts a vehicle's "passive" leaf spring suspension into "active" mechanical suspension. The Roadmaster System is equipped with springs that instantly absorb shock and dissipate load force energy. With or without a load in your vehicle, the results of using Roadmaster are greatly improved vehicle stability, balance, traction, and control.

    Roadmaster Active Suspension adds critical strength to leaf springs without deteriorating ride quality. The patented design prevents bottoming out, axle wrap, and wheel hop. This also improves handling by reducing sway and body roll while cornering and beefs up rear leaf springs for hauling with maximum safety. Vehicles consistently operating under load, hauling, or towing benefit from better fuel economy and load-carrying capacity. In addition, tire wear and suspension damage are reduced. Once installed, Roadmaster Active Suspension requires zero adjustment or maintenance.

    Features
  • Attaches Directly to Rear Leaf Springs
  • Increases Vehicle Stability, Especially When Towing or Hauling
  • Never Needs Adjustment or Maintenance After Installation
