ive never flexed mine....only owned it a month. once it runs, ill find somewhere to test it
Flex is slang for what is normally called articulation. It's when you drive one corner of your vehicle (usually the driver's side front wheel for ease of sight lines) onto an object that compresses the spring and shock of that wheel with the other wheel (front passenger side in this case) on a lower surface. This causes the axle to pivot on it's central point. The suspension does not need to be fully compressed/extended in order to "flex out" your Jeep.
Whether posed (96 xj) or not (actual use on a trail), it's always a good thing to test it out. Couple things to remember with flexing though:
1. Disconnecting your sway bars (quick discos for the front, ditch the rear) will increase the flex capabilities of your Jeep.
2. Make sure your brake lines are ling enough to allow for flexing out the suspension. If they're not, you could snap one.
