Hotchkis says they design it as a kit... Who knows, but the ride is firmer than the 47 year old soinds and at least 20 year old Monroe shocks they replaced. I don't find it harsh or jarring at all. Those fox shocks are money though!!!! The handling is firmer than say a stock 4th gen, but also feels much more planted with less lean in the corners. I'm not (yet) going full pro touring so sticking with stock arms at the moment.

My only complaint is I don't have any traction bars so the rear is kinda clunky
