Hi there.. i'm new to this and i have a basic question about lifting my 2000 XJ, i bough the lift kit "3" Rough Country Series II" to install it on my truck but i heard that when you lift it more than 2 inches you have to get something call "Transfer Case Drop" to put less strain and vibration on the driveline due to high mileage on the Jeep (mine has 115xxx miles on it), so i want to know if this is truth or not because i want to have a clean lift and do not have problems later on, if someone knows if this is required/necessary or not please let me know.
by the way i'm not gonna go heavy rough off road my plans are just going to the beach on deep sand and sometimes on the mud and stuff..
thanks for your advise i hope to hear from you guys soon

 

Every jeep is different. Put the lift on and if you have driveline vibrations you can try the transfer case drop or slip yoke eliminator.

 

I did the 2" BB and no driveline vibes. Normally, it's not till the 3.5-4" mark that this becomes an issue. Normally... But, a TC drop is a bandaid. It will do the trick- but why give up some of that ground clearance you just gained? If you've got the cash- a HnT SYE, front DS and like 2-3* axle shims and you'd have no issues.

 

Every jeep is different as stated, but i have personally had 6.5 lift on both a 96 and a 98 with no d.s. vibrations. At three inches you should be fine if you do notice some vibs, look into getting the ds balanced. Just to see if that cures it. thats a lot cheaper than buying a sye and new rear ds.

 

Dude your the exception!! Haha- 6.5" w/o doin any driveline adjustments and NO vibes?? Wow!! Lucky....

 

I didnt even have a tcase drop lol. It got wheeled. But now have sye

 

Man idk! How long you run it w/o the SYE? Did it ever give issues? On road/off road? Highway?

 

never and for several months. wheel really hard too.

 

can you guys explain me the meanings of this words?

SYE = ?
DS = ?
BB = ?
HnT = ?

remember im new to this and i dont want to mess up my lifting process just because i dont know what im using..

thanks!

 

Sye is slip yoke eliminator which goes in the transfer case and is the real fix for drive line vibes.
Bb is a budget boost meaning an affordable lift.
Ds is drive shaft

 

SYE- slip yoke eliminator
DS- driveshaft
BB- budget boost (coil spacers)
HnT- hack and tap

 

SYE- Slip Yoke Eliminator
DS- Drive Shaft
BB- Budget boost


The sye eliminates the factory slip yoke at the rear of the transfer case and replaces it with a fixed yoke and moves the slip joint into the driveshaft.
Driveshaft is pretty straight forward.
BB is for people who are too cheap (I for example have a BB) to buy a real lift, its simply a coil spacer that lifts the front around 1.5-2 inches and the rear usually uses a lift shackle but can use an add a leaf
