So what he did was that he installed bilstein shocks that was meant for 07-14 GM trucks. Based on the specs of what he installed and what was meant for our trucks, the strut for the older models is shorter, even though placing the snap ring at the highest setting lowered his truck. So if you were to use that same strut and place it on the stock setting, it would even be lower. On bilstein struts, you need to use the snap ring in order to install the coil.
