sounds like maybe 3.90's but im not sure. my 3:73's are around 2100, i think 4:10's are closer to 3k but i could be wrong.

I also have an '02 with 4.10's and I'm pretty sure you do to. Maybe even 4.30's. Mine actually sits just under 2400 rpm at 70 mph. I run a 275/40/17 tire. If you are on the high side of 2500, I would say you have 4.30's.

My 4.10's out me at 3K in 5th. I have heard some guys were at 2,800, but their trans could have been different.

99-mid 01's had t45's and the late 01-04's have the 3650, the 3650 has a bigger overdrive so rpms will drop a little with that tranny, i have switched my t45 out to a 3650 and have 3:73's, 70 mph is around 2100 rpms for me.
