Roadmaster Active Suspension (RAS) introduces their new Easy Install suspension upgrade for pick-ups and vans with rear leaf suspension. Once installed, RAS will reduce sway and body roll, improve load carrying and towing capacity, eliminate bottoming out, eliminate wheel hop and axle wrap, reduce fuel and tire costs when loaded, and most importantly, make the vehicle safer. RAS provides a smooth, comfortable ride, with or without a load. RAS comes fully assembled out of the box and has a 30-day money back guarantee.
