HD Torsion bars are available to order, they are producing more if you have been waiting to get them. Sway-A-Way is the company that Indy4x buys them from, so I just contacted them directly and asked if they were going to make more anytime soon and he said he had 4 people want them in the last 2 weeks so they decided to produce more and he set the website so people can now order them online and they will ship them as they make them. He told me 2 to 3 weeks. (Just ignore the incorrect spelling of VehiCROSS on their website)
