SYE vs. Transfer Case Drop

Ok I've talked myself out of a 2-1/2" lift in favor of 4".

Installing a SYE is probably over my head technically. It seems the choices for me are to drop the TC or to hire a shop to install the SYE then I'll install the rest of the lift kit.

What kind of shop should I look for to install a SYE, just a run of the mill mechanic? Tranny shop? Jeep dealership? Gay hair dresser?

Am I missing anything obvious here?

If you are thinking sye you will need to think about cv shaft also.

Any competent mechanic that actually fixes things, as distinguished from one who just swaps parts 99% of the time, should be able to do it.

I did mine in a couple hours myself and pulled the tcase out. Not very hard at all if you have good directions and good set of basic tools.

As stated above you need adjustable uca and a cv shaft. I had never done one before but me and a buddy threw mine on in about 4 hrs. We ended up leaving it in place and it was fine. I ran a tc drop for about a year and it is an option but with a 4" lift I would go with a sye. You dont have your profile info filled out so assuming you have an np231 here is a video that I used when installing mine. Only difference is he does it on a bench and did it in place. Either way its still the same process.

You are trying to lift the Jeep to create ground clearance but basically piss it away when you do a skid drop. Do the SYE and all things that are needed to go with it.

Do the SYE; the t-case drop is the way POS lift manufacturers get away with calling their lift "complete", it shouldn't be used as a long term solution.

And you'll want both upper and lower adjustable rear control arms if you want to properly set things up; the upper and lower arms don't have specific functions, they work together.

swap the straight track bar bracket extension for the angled SYE type also.

If you are lifting the Jeep to put bigger tires on and do not care about how the Jeep handles on or off road then a 4" and TC drop is perfect.

If you want a rig that has a better than factory ride on road and is an absolute beast off-road go LCOG. 2.5" SL, 1.25"BL and a MML. No need for a TC drop or a SYE/CV set up.

If you really want some incredible suspension throw in 8 adjustable CA's and a TT. This requires the SYE/CV but gives you an incredible break over angle.
