🚛 Elevate your haul game—stronger, steadier, smoother.
The RAS RoadActive Suspension 3611-YHD is a heavy-duty rear leaf spring upgrade designed for Ford F150 4WD models (2009-2022). It strengthens the rear suspension by 40-50%, reduces rear squat by up to 3 inches, and improves handling and stability without compromising ride comfort. The kit installs easily in about an hour with no special tools or adjustments required, making it ideal for towing and hauling heavy loads while maintaining a smooth, controlled ride.
