92 YJ drivetrain help

So I am purchasing a ford 8.8 with 4.10 gears to replace my blown 35. I also want to do a 4'' body lift in the near future or perhaps simultaneously. I also have to track down a dana 30 from a 4 banger to match gears, this wont be too big of a problem. My question is this. I know the gearing will match up but with the addition of a lift in my jeeps future should I get a SYE or a transfer case drop. I will be doing some off roading but nothing really extreme and commute to work (22 mi round trip) maybe 2 times a week on average. Not my daily driver but also not driving to the rubicon this weekend either thanks in advance. Not going the cheapest route but not exactly wanting to spend a whole lot either. The 8.8 is 500 with new all the hardware for a yj bolt in installed. Up to 500 for the Dana 30.Looking at the Zone 4'' body lift. What else am i looking at here realistically

Well, I would bet the reason that you haven't had any responses is because you are talking about 2 different items. Referring to a "body lift" when you actually mean a suspension lift.

Going to a 4" suspension lift opens up a new can of worms as far as what is actually needed. A SYE is a good idea, mainly because you are going to need a new rear driveshaft anyway, so you might as well get the SYE and be done with it. The 8.8 runs an offset pinion, so the stock shaft will need extended to make up the difference.

Extended brake lines are also a good idea. As well as a dropped pitman arm. (if these don't come in the kit)

When I did mine I replaced the shackles front and rear as well as the shackle bushings in the frame. Although the shackles themselves don't need replaced the upper bushings will. I went with an extended shackle and greaseable shackle bolts. They allow the suspension to flex easier.

I pray for you that you mean suspension lift and not body lift. Any decent 4" suspension lift will come with a TC drop. Don't be cheap and buy one without a drop pitman arm and TC drop. I have a 4.5 lift and have both with no sye and experience no vibration at all. As stated in other posts. Every yj is different, you may need one or you may be like me and not need one. And as stated make sure it come with brake extensions also or you'll regret it the first time you articulate

Good advice already, only thing I would add is if you have the money for an SYE and DC DS, that is the way to go. The TC drop is a band aid that will work, but it's not ideal, it actually robs you of ground clearance that you gained with the lift. If you don't have the money, do the TC drop and save your pennies.
