Fully responsive. Do not buy a two-chamber, which is cheaper. Google to see why a single camera is better. Why four stars? On the same car, a small 4x4 with oversized tires, the Rancho brand is a bit firmer and less springy. But these are fine on rough roads. I prefer a harder ride. I drive aggressively on and off road. I think (not sure) that Rancho shocks are made by the same people. budget accordingly. Undulating roads, speed bumps, dips (taken at an angle) and rails are no problem. The Rancho shocks give you slightly better side-to-side handling in a bumpy corner, but not by much.
