| :It's not a design flaw. It's installation error. Really? The product should perform safely within all reasonable camber settings. If not, it is a flawed design. The cross-sectional area where it broke is very thin. Threads cause natural stress concentrations to form, which can lead to fatigue failure. This will occur no matter how far it is threaded in. The threaded piece that broke is hollow. I think the wall thickness needs to be increased to provide additional strength. I don't remember if the SPL arms that I have are hollow or not, but I can't say that I've ever seen them fail in this manner. I hope Powertrix is set up as an LLC. A failure of this sort could easily result in a costly lawsuit if someone were injured or killed. He should seriously think of a product recall. If you recall, Noltec issued a recall on their Z32 upper control arms due to a design flaw that caused them to break. They employed a bunch of wanna-be engineers that didn't have a clue what they were doing. Oddly, they are out of business now. Did they get sued? Hmmm...
