Looks like you only lost about 60 rpm.

 

I put on 33" duratracs too. I lost SOME power, but I can still fly on the highway. Yeah, I have to downshift at times, but I cruise on flat highways at 75 mph in 6th gear running about 1,900 rpm (I think..) I think its just fine for now. I do plan on getting 4.56 gears when I move up to 35s, so I can keep my highway mileage good.

I ran a little test and running hilly highways leaving it in 5th nets me about .3 extra mpg, say opposed to shifting back and forth b/w 5th and 6th.

EDIT: my jeep runs a catback and intake and even when stock, it made a BIG difference in highway power. I also do not run a back seat in my Jeep, so its like 50 lbs lighter.

 

I guess being at Sea level and on flat ground makes the 35's and 4.10's good for me.
(Just measured again 35" KM2's @ 10k 33-7/8" )

...Thanks again for understanding IcyFridge!

 

I thought all the auto transmissions came with 3.73 ? Standard tranny was 3.21 with 3.73 for tow package option??

Just reread i see it was a standard.
