Yes, it will stop it... those AC springs are stiff enough for an f350 superduty.
The Radflo's have a spring rate and valving tuned specifically for the X. The pressure from those AC's would be the reason for your stock bilstein blowing up.
Since you can only get the Radflo's from PRG you may as well get the Deaver mini-spring pack for the rear while you're at it. Just don't forget new u-bolts.
