2'' spacer in the front and Quadrated 1.5'' HD leaves in the rear ... couldn't be more impressed with it.
I tipped the jeep over a few minutes after that photo HAHA.
Front shocks are good for a 2'' spacer, I'm not running into any flex issues yet with the front shocks. Rear shocks seem to be doing okay.
Steering stabilizer you shouldn't need to upgrade unless you go with huge tires. And even then, if you start death wobbling, look into what is CAUSING the issue and not getting a bigger stabilizer.
The steering will be off center a bit because the drag link isn't long enough ... that's something easily fixable.
