Yeah I'll agree with what TOYZX has said, Ironman is inferior to ARB, even though ARB do charge a pretty hefty premium, its worth it imo. I was told by a mate the reason he sold Ironman was the fact that it had a greater profit making ability for his business, cheaper, so it was more accessible to most people, and the big thing he said was the fact that he got a huge margin from selling Ironman gear compared with the rest.
On the durability front, I know of a handful of blokes that brought bars and had them rust within a year, none that i know of with an ARB. I have also seen the aftermath of a decent animal strike on both bars, Ironman? Replaced, ARB? Still good to go for another, seen this on a handful of vehicles too.
I don't have a dog in the fight with this one either, I have a BSF Bar anyways, just the fact of the matter is ARB is better, and certainly have used marketing well to increase the value of their product, over the rest, but, are people willing to pay the extra for the use of ARB? I would. I've also seen genuine toyota bars on the new model hilux totalled already, and one bloke I know has an ARB that was a replacement for the genuine and uses it as a livestock bulldozer and is still happy, so must be something right, I just cringe at the way he uses a 2016 SR5 Auto around the farm
