The 1.5" OME lift that I am removing from my '99 came with a 1/2" TC drop, but no extended brake lines are required. The same lift is found on the quadratec website, which shows a good list of parts, including shocks. leafs, and coils and allows use of 30" tires.
An SYE should not be necessary for anything under 3.5" of lift, depending on the net result of your driveshaft angle, which can be correctly cheaply by the TC drop and/or shims. (My first XJ with the 3.5" netted about 5" of lift, and I used a 1" TC drop. Tolerable vibes and no loss of trail performance).
I write this wondering if that is the same lift you are referring to. What tire size does your OME lift allow you to run?
