The arms are light weight chromo. Not the same as the regular LT fireball arms. Notice the way the upper arm balances off my hand in the photo. As far as the swinger, is there any one doing a light weight square tube? I've seen what I've seen from several manufacturers, and there's no way a straight round tube style swinger will ever go on my bike. A ladder bar or arched swinger would be cool in Ti, but like I said it's not 300' so guys don't wanna deal with it. Money is not the issue. I've saved up and hoarded parts for a year.
