I am piecing together a 6.5 in lift for my 89 xj. Im using rustys front coils and rear leafs but im thinking about adding 1.5 inch shackles and spacers. I was woundering if i can go that high without a SYE for now. Im putting 6 degree shims on the read and have a 1 inch drop on the transfer case.
I am also using rough countrys control arm drop kit i will eventualy put the long arm kit on it whats the most u can get out of a control arm drop set up i know it will hinder my flex. Any information will be greatly appriciated thanks.

 

i think theres a sticky on naxja but i can't get on their page at the moment, its called whats and sye and do i need one or something like that... id start there, i know it says that a tcase drop is just a bandaid...
i like your jeep either way...

 

Most seem to experience vibes at about 4 inches without an sye...

 

just finished my 3" RC install and i get vibes at 30-35mph but fine after that.

 

I have a 3.5"RE and have no vib at all but I do have tcase drop and nothin else

 

Every jeep is different, lift it and see if you need it.

 

Ya I mean my buddy have a 4.5" with 1"tc drop and still gets vibration his is a 01 and mine is a 94

 

i did a 3 inch frankenstein lift on my 00, and i felt heavy vibes at 10 freakin mph, but then i dropped the TC and everything is smooth sailing

 

see, i'm sitting at around 7 and i have no sye or t-case drop with no vibes.
but i have a yj yoke on my rear drive shaft and 4* shims.

 

ill be sittin round 7 when im done so ill try and find me a slip off a yj i didnt even think about that thanks for the info my jeep vibrateslike crazy but it comes from everywere so i dont think that will make much diffrance

 

ive got 3inch rough country and i need a sye bad it started out just at 55-60 but only got worse, i put in new u-joints and its been helping but still need to get one

 

well my jeep has never seen 55 i dont drive it on the road much but eventualy i want to get it to were i can so ill probly end up gettin one one of these days

 

I am at 5.5" and I did a t case drop and shims in the rear. No vibes but I have seen where I am pulling out of the yoke quite a bit. You may be ok if you don't wheel hard but if you are in the middle of nowhere and it pulls out, would it be worth it? I am getting a hack and tap next just for this reason.

 

what kinda drive shaft do u use for one of those

 

The hack and tap I am getting comes with a refurbished XJ/ZJ/TJ front driveshaft.
