Cracked fram

Hello all I have a 2014 rzr s800ho first I would like to say yes I do jump my machine occasionally they jump more on a one hour show of destination polaris or dirt trax tv than I have since I bought the machine new I like the hard and slow trail stuff with a logging road in there . So my problem is a cracked frame were the sway bar mounts to the round tube right at the weld and almost all the way round so I was wondering if this could be caused by the sway bar adding presure to the fram when a lot of flexing goes on with the wheel articulateing up and down in the rocky stuff , and what do I do next . I removed my sway bar . Do I just weld it and add a gusset or two and hope for the best and enyone have the same issue with the 2014 thanks for the comments
