In my case, the Bilsteins have made my truck feel more planted and well behaved as the "street princess" that she is. The OEM shock is simply not designed for a truck, let alone a spacer. The OEM shocks would bottom out easily and were bouncy. Any bump in the road at highway speeds would unsettle the suspension causing the bounce mid corner. Comparing a 2500 to a Bilstein 5100-leveled 1500? My '16 2500 CTD rode much "stiffer" than my leveled 1500. To the OP: IMO Get the Bilsteins if you can, for the money it is the best option when leveling.
