I've ridden the Fireball arms for a season now... They are very good, and super light... If you're thinking about any drag arms (a-arms, axles, or swingers) I'd give Roger a call. He's been really helpfull. Good quality stuff too. I had him make me a +13 swing arm for my chassis, with the no ling moved forward 2" so I could have my shock at a perfect angle. he did it at no extra charge.
