I was wondering if it is really needed on a 3.5" lift setup on a JL. I see a lot of threads recommending it.
Those that have a 3.5 lift, did you flip the drag link and relocate the track bar?
Rear relocation bracket is a must. Without it, you’re drive shaft will hit your gas tank at a full flex. Front flip/track bar relocation would probably be nice but it’s far from “necessary”. BTW - I am running over 4” of lift.
