Ive done a 4" lift so far. Tcase will need to be dropped i have not done this yet as i am looking at linkage options vs the drop bracketety in the zone kit. Jeep isnt a daily driver so not a huge deal but i am back to the ordering parts phase. I dont plan for any more than the current 4" zone suspension lift. I do plan to do a motor mount lift and a 1.25" body lift soon with the goal to raise the belly up. It appears there are 3 legenths of sye. The standart sye. The super short sye, and the extreme short sye. It looks like with the latter 2 options you end up with a tone ring speed sensor. Also looks like a $200 plus option with the extreme short sye. Is this going to be nessisary for the tummy tuck and lift? Also how do i calibrate the speedo at this point?
