Someone please educate and advise me. I have a stock '14 Jeep GC Overland that has Quadra-Lift. I have a leaking rear shock so I need a recommendation on new ones. Every shock I've seen says "don't use with air bags". I want to upgrade somewhat from the standard dealer shock that failed so quickly for me. Why won't the regular shock (without Q-L) work when you have Q-L and what upgraded shock will work?
