Any add-a-leaf kit is garbage. You should be OK with a Rubicon Express 2.5"
spring lift without getting a slip-yoke eliminator.

You really need to address the body mounts before you consider lifting.
 If they are all rotted, you might want to find a different Jeep to modify.

The YJ (yuppie Jeep) has soft cushy springs to start with, so an add a
leaf isn't a bad way to go.  You can go to a real truck spring shop
where they don't use gold plated tools and think they are selling
platinum springs like some 4x4 shops do and get your current pack
re-arched, then add or replace one leaf with the pre-tempered and arched
add a leaf.

I had this done on the old front springs of my CJ7 in 2000 to match the
new arched spring pack I had to put in the back due to busted leafs.  In
the back they took a stock new CJ spring pack, arched them for 2 1/2" of
lift and replaced the first spring down with a generic 'keeper spring'
or 'add a leaf' already the correct size and arch.

I have done some serious off roading with a warn HS9000i up front and my
spring have held perfectly even for these last 7 years.  I also run
fully loaded off road to get 'way' back into the bush for a base camp.

Including parts, the new back pack and the keepers, I believe it all
cost less than $500.00.  That did not include shocks.

A lot of people, including myself,  run standard 4" lift with a 1" drop for
the transfer case.  No vibration at all.  Never broke a u-joint in 50K
miles.
