When driving over a speed bump slowly, my truck feels like it ran into a brick wall. When I speed over a bump, it's smooth like butter. How can I make my truck have a constantly smooth ride and be able to "glide" over potholes or small rocks ect.? I never go off-roading, but I wanted to know what parts I can upgrade for a smoother ride. I have new Toyo tires now which helped, but what about smoother impacts? All suspension is stock, truck info in sig.
