Front Bumpstops

This is what happened to one of the OEM front bumpstops when we conducted a testdrive before installing the Jounce Shocks. Notice how the rubberized material was damaged by excessive force during a hard bottoming-out. The vehicle speed at which this damage occurred was 15 mph. We were surprised to learn just how susceptible to damage these bumpstops were. The Jounce Shock system doesn't replace the OEM bumpstops. In fact, the installation instructions recommend cutting them in half with a Sawzall and reinstalling them as backups in case one of the Jounce Shock cylinders should ever fail.
