My stock JK has front DANA 30, rear DANA 44, axle ratio 3.73 and
has rear limited slip differential.

I want to take a moderate upgrade that will take full advantage of
my current axle ratio and slip differential.

So my current plan is

keep stock front and rear axle
add front axle lock (maybe another limited slip differential?)
3 inch lift (budget, full coil or short arm, not decided yet)
33 inch tire

Does it take full advantage of my current stock setting?

Hints and suggestions are welcome

 

you can run 33" tires stock and without any problems. 3" will allow you to run 35's with ease and i would recommend that if you are going that tall. being that you have a rear limited slip, i would recommend getting a front selectable locker like arb makes. that would give you the best advantage on and off the trail.
