Yes, there is some confusion as SuperSprings has three different products. Go to the following YouTube video, and all three are explained. Most people use the bump-stop helpers. They are the least expensive, easiest to install, and provide a great deal of support and ride improvement. The others are more for commercial use or instances where you need A LOT of assistance.
