Hmm. What are you planning to do with this truck? I've gone through the process of SAS and lived to regret it. It's not that the finished product wasn't good, its just that it was expensive and unnecessary. I always have the mindset that I want the most capability out of a platform when in reality I'm just a materialistic dumbass sometimes. A few things: That Duramax is a well engineered motor. Don't jack with that. In these modern times, IFS has more opportunities than they had ten years ago. The main reason SAS is so popular is because for the longest time there were no options to upgrade IFS. There is now. Dynatrac makes a Dana 60 centersection. You can get bulletproof half shafts. Lockers. Custom A-arms. There are options to maintain the well engineered attributes of the truck. Don't drink the SAS only koolaid and certainly don't replace the DMax.
