I'm about to become the owner of a new (to me) 2020 Ram Rebel. I've confirmed that it doesn't have the air suspension. I'm planning to add a lift. Do all Rebels have a 1" lift? If so, this will affect my lift math. I'm looking at Bilstein adjustable shocks, and if I remove the current ones, would the total lift be about 1" less than the new adjusted shocks (i.e., a 2.8" adjustment would net 1.8")? Thanks in advance.
