My '93 YJ has a 1.5" shackle lift now running 31x10.50 with no problem. I would like to run a 33" with clearance so the tires don't look stuffed in the wheel wells. Would a 2" RC leaf kit coupled with the existing shackles be enough? Or would the 4" leaf kit be better? I was also thinking of a 2" leaf kit paired with a leaf over axle kit...any ideas?
