i have had no issues with mine whatsoever IMO these things can take a beating the reason for the cracking is a crappy install, a bracket lift done right is welded into place once the alignment is completed superlift says this doenst have to be done and in reality it doesnt but once welded it WILL NOT MOVE , im very happy with mine and will never run another lift the ride is much better than stock it rides better than my 05 ram with 60k miles on it . you also have to maintain your lift i get mine chekced once a year with the installer and we look over it so far no rust no cracks and everythng is tight and in order personally i would highly reccomend superlift but NEW used who knows what your getting just like with anything used
