All Rubicons have 4.10's. 35's won't be too bad, 5th gear will lack power,
only be good for flat or down hill. I put the speedo gear in my TJ after
the gear change... worked great! Very easy to do.

I have 3.73 on my 2000 TJ with 33" and you can really tell it when you get
in the mud, or just doing a water crossing. Need to bump mine to 4.10's or
4.56's but don't have the money now. I will do the speedo recal then, right
now I just remind myself that it is going faster than it says and add about
2% when I have to use it for mileage on expense reports.
