It depends on what your doing. The IFS definatly has a better ride than a straight axle but straight axle is stronger beacause there are less parts and less moving parts to break. However the IFS is extreamly strong and has very few problems. The IFS also will pull better over uneven ground because it lets each wheel get better traction.

To answer your question in comparison of the two Id say over all its an advantage. :cool:

I have always loved SFAs but my last 4 (counting my current 2) have been ifs chevys and i have yet to have a problem and have only ever gotten one of them stuck 1 time! If i had not beefed up the steering on my truck i would have broke it by now but not the suspension its self!

Advantage! Has anyone ever seen a duramax axle hop with the front end while pulling? I havent, seen many SFA do it though. Like what was said before the abillty for the front tires to move seperatly makes a difference.
