We haven't tried the Tow/Haul System personally, though we did test out the Sport System on our 2018 F150 Budget Build Truck. Personally, the Falcon Sport Kit arguably rode the smoothest on the street. However, I don't know if they're worth the price jump from the Bilstein Stage 2 System we offer. That being said, if you are looking for the absolute smoothest street ride, the Falcons are probably your best bet.
