Well, I can say a bunch of s*** about a company with no real reason, or I can do this:
I have owned at least 4 sets of OME springs and coils. I have owned Alcans. I have owned Slee custom springs for an 80. I have owned ARB bumpers. I have owned Slee bumpers. I have wheeled the s*** out of all of it.
I own a GX470 with Iron Man 4x4 springs and shocks currently. They work. They don't just work a little, they work amazingly well. They took a beating, the spring rates are perfect so far, and the shocks are dampening without fade no matter what I have thrown at them.
Aside from conjecture and hearsay...does anyone have a set of Iron Man 4x4 equipment, on a truck they own, that doesn't perform well? Are you an installer, that once you installed Iron Man 4x4 equipment you or your customer found problems?
If you are not qualified to answer the above question you are simply not helping anyone learn anything about anything.
Don't be a troll, don't feed a troll.
