WTF you going around for, that IFS will kick the crap out of those heeps. Just lock it up.
$300 is a pretty good deal for an IFS lift. If you're fairly new to the wheelin, I'd go with that for now, you can run 35"s with it, no problem, and you'll learn a lot. As yo ulearn, you'll figure out your trucks limitations, and decide whether you really need a SAS or not. Then, once you get to that point, you'll probably have more wrenching experience, and be ready to dig into it
