Got a 2dr x with 3.73 gears.
Wanna do a 2.5 coil lift and 35s
Do I need:
New drive shaft?
Do I need sleeves and all that?
What gears for mud/fire trails and dd?
And was thinking 5100 shocks?
Anything else I am missing?

 

I'm doing the same thing right now. You might need a Procal or other programmer to reset your spedo and shift points and wheels or Spacers depending what you are currently running.
Happy hunting!
I've been doing homework for a couple weeks and think I'm ready to pull the trigger.

 

What about gear size?

 

A lot of guys, including myself, cut the pinch weld. Others, though, swear against it.

Auto. Sorry the one thing I forgot to add

 

Unless you plan on going to 37's, 4.88's are almost overkill as I'm finding out myself. 4.56's will get you closest to stock ride if you've got a 6 speed manual...

 

I've got a right hand drive auto 08 2 door on a 4.5" lift and 35 x 12.5 tires with 3.73 gears and didn't bother with anything else and i haven't ever had any problems with anything or have any signs of any problems.
and i put my jk on a lift weekly to inspect it.

 

Do you have a chip or anything?

 

Nope nothing more than i mentioned.
