RAS rear-leaf spring suspension upgrade from Roadmaster Active suspension. When installed on pickups used for towing, RAS will change the performance of the rear leaf spring by converting passive rear-leaf spring suspension to mechanical active suspension. Provides improved vehicle load carrying, handling and stability while reducing sway in crosswind conditions, and a more comfortable ride with or without a load. Check out to see it in action.
