Thanks Dan, they're forged and can handle 4500lbs each according to spec. As far as my towing capacity... I can't really say. I can tell you what I'm LEGALLY allowed to tow, and I can tell you what I HAVE towed lol. She's got 5 extra leafs per side, airbags, and 1/4" frame stiffening front to rear. It STILL flexes more than I'd like with a heavy load on the back, but such is life with a sneeker unit.
