It's commonly referred to as SFA, Solid Front Axle....never heard of SAS, but it's all good.
I've spoken with a few techies about such a thing (IFS to SFA) and they firmly believe that the IFS on the H2 is amazingly better performing then you'd imagine and there'd only be a slight margin of improvment in performance. Dollar-per-value, I'd put my money on the front-locker first and foremost.
A lot of people who are really into solid axles overlook the benefits of the independent set-up. When your axle starts lifting, it may push the other wheel downward, but it also starts turning the wheels/tire on it's edge. Also, I don't think we sacrifice that much clearance with the IFS.
Beyond that (and taking in a dose of huge reality)...the H2 just isn't ever going to be a rock-crawler: it's too wide, too long a wheelbased and just inherently doesn't have enough clearance. All that work putting an SFA on an H2 is like putting small wings on a hippo: it's never gonna fly anyways!!!
Lastly: some of these non-Hummer guys walk on egg-shells and try to oblige us at every turn...it's really not fair to jump on them and dis their stuff just cause they're not Hummer owners. IF they get nasty/mean...then fine, light 'em up....but if they are cordial and play friendly, let's learn and keep an open door policy.
