Created in North Carolina in 1992, Roadmaster Active Suspension offers the ultimate leaf spring suspension upgrade to vastly improve handling, capacity, and towing. The unique RAS design resolves the conflict between ride comfort & load handling by converting a "passive" leaf spring suspension into an "active" mechanical suspension. This suspension solution yields additional benefits: increased vehicle stability, better balance, and greater traction control when traveling without cargo. Patented active suspension technology delivers vehicle-specific fit, powerful load-absorbing coil springs, and maintenance-free operation.
