Most, if not all, Steelhorse stuff is crap. I have looked into those flares as well, they are much cheaper than the other brands. Everyone I talked to that had a set said that is because they suck(to put it bluntly). They said that mostly they just crack. Not real flexible.
I have never heard of Steelhorse even having a warrenty on anything. If they do, they don't honor it for things like fit and such(most of their stuff won't, you have to trim, and redrill holes, etc.).

Seems as if everyone would be correct or at least consistant with the feedback that we've gotten. Go with the factory flares unless you need the extended ones, then you might have a look at the Bestop flares.
