have 93 yj, 30up front, 8.8 rear both geared 4.10, 5 sp, 6banger with 35s, runs good, has good power, is it worth my time changing to 4.56 gears, since i do have them available, out for 8.8, have in another axle for the d30 so they would be used, but look good. will it make any difference. worth it nor not. thanks

My Jeep is setup almost like yours, minus the overdrive tranny. If I had OD for the highway and free 4.56 gears, I'd swap.
 
If you can do the swap yourself and don't mind the work, x2 on the free gears. However, from my experience you won't see much if any seat of the pants difference!

im not sure about 4.56s, but i swapped from 4.10 to 4.88 and notices a huge difference on startup and at interstate speeds.
 
if you decide to sell either set of these gears let me know i might pick them up
