Hey guys, I'm going back and forth between the 3.5 RE super ride kit and a Zone 3 in kit. I was wondering how they hold up over the years. I have had my XJ since 01 and in 05 replaced the rear springs with HD ones form quadratec that are now shot. It is my dd, no winch or bumpers, just trailer my atv in the summer, and take it mostly on fire/logging roads, which is what alot of the trails are around here. I want to know if either one seems to hold up better over time? Like 5+ years. Thanks. Pat
