Rough Country vs Zone Offroad

[jimbrown1]

Can anyone explain the differences, if any, between the Zone 3.5" suspension lift kit and the RC 3.5" suspension lift kit? I've read all the hoopla on the RC kit with it having many issues, possibly being changed after RC discovered the issues everyone had been complaining about, etc. I considered the RC 5" kit but it won't allow me to park in the garage at work so I'm having to step down a notch or do nothing and leave the truck as is.
