Ford F250/F350 2011-2023 RAS® RoadActive Suspension 3611-SHD [Without Factory Top Overload Spring]

RoadActive Suspension (RAS) offers a more complete solution for pickup owners seeking to enhance their vehicle's stability, reduce rear squat, dampen excessive rebound, improve performance, and provide same-as or better-than-stock ride quality, all of which are just as important as simply reducing rear squat. Using high-quality components proven to last, RAS provides a seamless blend of improved load handling, performance, ride quality, and enhanced overall performance at all times.

Unlike other suspension helpers such as air bags, RAS can strengthen the rear suspension by up to 50% in a progressive manner, but it, like no other suspension upgrade, can increase the manufacturer's weight ratings. From a fitment standpoint, RAS often fits lifted trucks without issue, though users should check for possible obstructions before ordering and contact RAS directly if there appears to be a problem.

Yes, RAS will help reduce rear squat by up to 2-3 inches, in addition to its focus on improving overall load handling, stability, and performance without hassle.
