Because of market size and demand, RoadActive Suspension(RAS) is most often compared to Air Bags or traditional helper type suspension upgrades. While the Active Suspension system certainly reduces rear squat, it does so much more. Simply comparing RAS with Air Bag/Helper Type suspension upgrades is not a true apples-to-apples comparison. Put simply, RoadActive Suspension offers all the same benefits as Air Bags, helper springs, sway bars, and traction bars, all in one unique product. Tuned and matched for each pickup truck size, the variable rated tension coil spring applies proportionate to force that is applied. This simple yet brilliant concept, coupled with proven high quality components, translates to it being one of the most well rounded suspension upgrades on the market
