If I go with a 4.5" lift and it comes with a transfer case drop do I still need a longer drive shaft or with the drop will that make up the difference? Thanks in advance.

The transfer case drop is the alternative to the longer driveshaft/SYE. Some will argue that it isnt one of best alternatives out there, but it will get the job done.

There are a lot of other threads out there discussing this, do a search and you'll see. Some go out wheeling for the first time with this setup and things get messed up. Others have been running the same setup and wheel consistently without a problem.

Longer shaft/SYE vs t-case drop
Anyone?

Sorry I replied before I read the rest of the post. I'll do a search see what is best. I'm not into doing any crazy stuff mainly because it's my DD but I would like to get it up off the ground. I had a 96 with a 4" lift and no sway bars which was my bush runner and that seemed to go anywhere.

i have the RC4.5 x series kit and i used the t-case drop and i got a manual trans crossmember and mine is vibration free. there isnt a huge difference between the manual and auto but i really didnt want to shell out the money for a sye kit and different rear driveshaft

T case drop will put more stress on motor and transmission mounts. Sye and be done.

Yes. I don't really want to drop the money for a new shaft and SYE. I do have a 5 spd so your saying with the manual trans crossmember it should hold up a little better?

Moparguy45

Where the trans mount bolts to the crossmember, on a manual trans crossmember it sits lower than a auto trans crossmember so it gives you a little bit more of a drop to help out with getting rid of vibrations. brookhart63 could be right about putting more stress on the mounts but im yet to have a problem with them.

How long have you been running your setup?

Moparguy45

for about 12,000 miles. The jeep had 155k on it when i did the lift also

I've had to replace a driver's side motor mount and a tranny mount running with a t-case drop. I'm about to rebuild my t case and i'm gonna shell out the extra money for a sye. For a dd, a tcase drop probably wouldn't be that bad but i beat on my rig often.

And just to add..i do run a 4.5" with shims and a t case drop without a vibration but i'm still gonna ditch the drop for a sye when i rebuild my 231

A longer drive shaft and cv driveshaft are two different things. If you lift it without a sye and go offroading, you run the risk of the driveshaft coming out of the transfer case. You can get a longer one. When you have a sye, you get a cv driveshaft that is not necissarily longer but it has a joint that can move around. People rarely get longer driveshafts. Just to clarify. But someone please correct me if I'm wrong.

what about the sye's that use a front shaft in the rear? are those only the hack n taps?

Jeepxj1234

No you can use them with any sye. I think that they need to be lengthened and balenced or something though

Have mine around 5" with nothing more than the T-case drop and I have NO vibes or noises
