I am swapping out lifts and have been looking at 3" to 4" kits.
Some come with transfer case lowering kits, some don't..
Is there a reason I should or should not lower the transfer case????
Does it matter if I do not? (early wear issues or whatnot)

 

Do you have a TJ or a JK???? The way the jk is setup, you don't lower the transfer case on any lift.

 

I have a JK.
I was looking at lifts labeled for the JK and black diamond lift
stated it came with transfer case lowering equip.?
Maybe I misunderstood.

 

Maybe a misprint, no transfer case lowering kit is made for the jk.

 

Well thanks for the info.

 

lowering a t-case was only done on TJ and YJ's and were just a cheap fix that helped prevent vibrations after installing a lift. the proper way to fix that was to install a slip yoke eliminator, new drive shaft and adjustable upper control arms to set your pinion angle. the JK has a fixed yoke and CV joins on the drive shaft and so you do not need to worry about vibes or fixing them.

 

Thanks for great info and explanations. I completely understand now.
Knowledge is awesome.
Thanks.
