Yeah SD can prob answer your question better than most on here.

It would help the angle to get a high pinion 60 or 9" rear. You should look into a TRUHI9. Apparently they have the highest pinion outta the 60's and 9 inchers.

Also, 4 inches in addtion to SOA would give you about 8-9" of lift, not 6 1/2". That's quite a lot of lift. What size tires do you want to run? What type of wheeling do you want to do with the Jeep?

Gun it and run it!
