i recently (couple months back) upgraded my 6speed from 3.73 to 4.88 which is running 35s... I did the gears and ARBs at the same time as well...
The 3.73s were ok for street use..awful offroad for hills or rocks! The 4.88s are great!!! do it! sooner the better! Its great on the street, and since I dont push it over 70/75mph the rpms at most are hitting 3k which is just fine..and actually in a good part of the powerband for passing, stiff breezes, hills, etc.

I have 35's, 3.73's with an automatic, and I'm here to tell you that it fuckin' blows. Sure, it's "livable," but the performance sucks. It's even more of a dog off the line, and the transmission never stops down/up-shifting on the freeway. At ~75mph, the 3.73's push anywhere from 3100-3300 RPM. I'll be putting in 5.13's here in a few weeks to bring it back to where it needs to be.

I had 3:73 on an auto with 35s for 4 months and the damn thing was always downshifting on regular freeway ups and downs,when i got the 5:13s there was no more down shifting or having a hard time keeping your speed or anything it was smooth sailing, I love it and got alittle better mpg too
