and in those corner how does everybody know his tire didnt fall off sending him rolling, breaking the bar.
True story, most "kits" are sub par IMO.As shitty as steel rims are, they do NOT fail like that in normal circumstances. If the lugs loosen (which you can plainly see all 5 are still on the axle) the holes will be beat into an oval shape by the studs - then the studs will fail or the tire/rim will depart prior to that. It will leave the rim mostly intact, save the distorted mounting holes. This rim failed from a single MASSIVE overload - the tearing from the mounting holes is in one direction only and removed a good section of the rim. There is NO WAY you could generate the force to do that by simply turning a corner. My guess is it hit hard after rolling on that tire; a single massive overload resulting in an instant failure.
If that TRE was installed wrong or not, I won't really comment. AFAIK, it might well be considered acceptable to have that many threads showing, providing he still has full engagement of the threads in the panhard bar. I wouldn't do it like that, personally, but I also wouldn't run half the stuff that comes in 'lift kits'.
But you can't blame Rusty's, alot of the parts that have failed(in the past not in the last 3 years) were not built by Rusty's just sold by him. And from what I've used and know of Rusty's I'd trust his stuff with out a second thought..
