I recently read a thread that said that the numbers outlined by Bilstien are the increases in shock length and don't translate to the actual amount of lift in the front end. It said something like actual lift was something close to double what the increase in shock length was so setting 3 at 1.24" would translate to something close to 2.5" of lift....Just wondering if there's any truth to this since I have close to 3" of rake on my Sierra...
