I have a feeling warranty issues are gonna be a real problem and vary by dealer. The dealers that are taking care of their customers with mods will take good care of it's Rubicon customers. The urban dealers that sell mostly street Jeeps, will have issues warranting what they may consider abuse. D44's, lockers, 4:1, that thing is built for abuse.
