Broken Sway Bar

[Jramos013]

Hi everybody, i've been lurking in the forum for a while but finally joined today. This forum has been a great help for me in the past. My jeep is a 06 65th ann. TJ, rear Dana 44 with a 3.5" lift. Stock arms, crown vics rear springs. I upgraded the rear swaybar with a steinjagger HD one last year. Today while removing the exhaust to replace the RMS i found the sway bar broken. I contacted steinjagger and they sent me a replacement right away, but in still wondering what might have caused this? This is a DD jeep, mostly on dirt / bad roads. Could it be just a bad bar or can something else cause a sway bar to break like that?

The heat treat was not done correctly and the material was too stiff for the amount of rotation it endured. What was wrong with the stock bar and where it that one mounted?

Edit- looking again, I see that it appears to be a tubular bar. That will most likely continue to fail in that application.

Thanks for your reply, im very happy with the black magic brakes!

I replace it because riding with the stock one after the lift the tub was swaying more than usual, so i got that one to try and fix that. The ride improved greatly until it broke
