These are the components that make up a JounceShock. On the left is one of two styles of mounts available that attach, via a thread-on design, the JounceShock body to the vehicle's frame. This mount is welded to the frame. In the middle is the JounceShock itself. They are available in two sizes: 1 1/2 inches and 3 inches of travel (shown here). The 1 1/2 is 6 inches long overall, while the 3-incher is 9 inches long overall. Both bodies are the same diameter and use the same frame mounts and feet. Below is the thread-on nylon "foot" that comes in contact with the weld-on "target" below it when the vehicle's suspension travels upwards. The feet and targets are available in corresponding convex and concave shapes to fit different applications.
