Here is my truck with a Zone 4.5" and stock wheels (1.5" rear spacers). Stamped steel arms and zero rub. The tires are 275/65 20's (34.5")
If you work/live in or near Downtown, I'd be more than happy to meet up and let you see the truck.
BTW, if anyone is looking to change their 4.5" lift to a 6.5" lift, I have the kit listed in the classifieds forum.
