All one can do on the internet is make an educated guess. No one knows how much lift a spring will give your TJ because the sprung weight varies on every TJ (soft top, hardtop, half doors, full doors, rear seat, winch, aftermarket bumpers, spare, no spare, driver weight, the list goes on and on). I can suggest 2933/2942, but hard to know if that will be 2 or 2.5 on your rig.Looking for the 2in lift to run 245/75/17 takeoffs with a front winch and avoid the SYE/track bar/etc changes.
