New Shocks - Still bouncing, chattering and slamming into potholes

Bilstein 5100s are absolute garbage, and Bilstein unfortunately enjoys a good reputation, so they keep selling garbage. I know took me several pairs on my personal vehicles to realize this conclusion.

First thing I would do is throw those in the scrap bin, and get real rebuildable tuned shocks, like Fox performance series 2.0, preferrably from AccuTune offroad because they tune well for better ride and actual damping force improvements, unlike Bilstein.
