Finished the lift

Yes, you will need a new driveshaft.

Depends on how often you chew up ujoints and how bad the vibes are.

If you don't want to buy an actual t/c drop buy some longer bolts and a bag of flat washers.

That will at least let you know if that's enough to compensate.

Maybe we can meet up one evening this week and you can compare your Jeep's vibes to mine. You're in Pike Creek, right? I'm available tomorrow and Thursday evening. Maybe Sunday afternoon as well. Let me know.

Pretty sure i told u a sye and cv were needed with the lift :). The t-case drop will help along with a motor mount lift but those are a band aid more then a fix.

If you drop the t-case you'll want to shim the rear axle so the u-joint angles on the drive shaft match. Otherwise you'll get vibrations and be blowing u-joints quickly. I personally don't like t-case drops because they are counter productive to the lift you installed.

I used to wheel with a cheap bastard that had a 6in lift and no sye or t-case drop. His driveshaft would come out of the slip yoke on the trails if he got high centered. It was frusterating to watch T-case drops suck if you plan to wheel it because youll spend all day getting high centered. If its just for the street you can get by.

U are also gonna need 4 or 6 degree shims unless we but the 8.8 in at the same time as the sye.

Astape... when we did the 44 swap we had to do almost 12° on the spring perchs... i know a guy in laurel that has a 8.8 with 4.11's in it i cam check to see if he still has it and get you the info. And honestly... with 2 inch shackle lift and 4 inch spring lift good luck with the alignment... i got rid of boomerang shackles and went with revolvers in the fron and z-pacs in the rear... that much lift on the shackles will jack your castor or camber up i cant remember...

I believe Aaron was saying that if they did the 8.8 swap at the same time then they could cut off and weld the spring perches/shock mounts in order to position the pinion up at the correct angle instead of having to use shims.
