In the mountains you would find 4.88 ideal for 35" tires, with even lower gearing like 5.13 even better. I find it odd you would say 4.56 on flat roads is good for 35" tires but the lower 4.88 gearing would be "too low" for mountains. I often have trouble following your logic behind some of your recommendations and this is a very good example.

Look a couple posts up. I ran 37s behind a 4 cylinder.

RE5.5 springs are too tall for 35s. 5.5" of lift is something you can get by with, but it is still too tall for 35s.

i have 4.5" lift & 2" BL = 6.5" lift

IMO that`s not too tall.
in the rear i needed to extend the BSs 2" and in the front 3" (have to add 1" in the next days).

iīm really jealous. iīd like to install tube fenders instead of longer BSs in the front. but here the tires have to be covered by the fenders and i couldnīt find 7" tube fenders yet.

My 35s and similar speed give me similar rpms...is it possible that the build sheet is wrong? 3.73 should be lower in rpms by more than a couple. Unless nico has 5spd and I have 6, then we are the same cruising i guess.

My cars have higher rpms than my trucks on highway...the jeep is almost a truck and designed more with torque than HP...where cars are the other way around. I would understand you if my jeep did not have 80% torque at around 2k rpms as most trucks do. My excursion runs 2k at about 70. Cars normally have higher 'redline' than trucks therefore normally run higher rpms.

You think the jeep is lugging at 2k?

I am not trying to turn it into a car, but keep it from 3k rpms when i am still not doing the speed limit.

Weird that my rpms are near Nico's and we have substantial diff gears

At 70 mph, my engine was only turning over 2700 RPMs with 35" tires and 4.88 gearing, nowhere near 3000 RPMs.

sorry for the confusion.
here in germany we say it in another way. for us 4.88 is higher than 4.56 and 4.56 is lower than 4.88.

i wanted to say that in the mountains the RPMs arenīt high enough with 4.88 gears (with my 0.69:1 O/D), 5.13 would be better.

here in the flat country 4.56 is enough. the RPM is low enough for a good mileage and high enough to hold the speed and accellerate moderate if it goes up a bit.

I'm betting that even in Germany that 5.13 is considered a lower ratio than 4.88 is. The same confusion exists in the U.S. for most people.

Cannot believe how happy I am going from 215/75s to 35s without changing gears!! should be impossible.
I've got the 3.07's on my '06 and was planning on having to invest in new axles and new gearing right after I rigged it. but after driving it with 3.07's and 33's (I too can start in 2nd, and when I start in 1st, I don't stay in it but for like 2 seconds; and cruise down the interstate and 75 with comfortable rpms and still carry hills) I now plan on just finding some rubicon axles with 4.10's and I can't imagine being unappy with that, it I understand for crawling you want to be geared really low, but for some off road and some on road, I really don't think I would want more then 4.10's on 33's.
And as far as lugging my engine at highway speeds, the way I view it is if I can run comfortably, and carry mild hills without punching it or downshifting at highway speeds in 6th then I am happy. Certainly not trying to debate you knowledge Jerry, I appreciate all the sound advice you give on the board, I am only saying what works for me.

I'm with ya...I hated my TJ on test drive but knew it would be better with 33 and I would not need to regear. I was surprised that I could still start out in 2d with 33s so I went to 35s. It feels right to me as well. 4.10 are not much diff than 3.73s...probably perfect.

(RE stuff comes grey in color...I have nothing grey on my TJ so I painted most black and the springs red to match )

And 5.5" is perfect for 35's

You have a stick... my 3-speed does fine with my 32's and 3.07's. Even going from Phoenix up here to Payson it does pretty well. I can keep it at 60-65 constantly with minimal down shifting.

2.5" OME HD springs + 2.5" spacers in the front and 2" spacers in the rear.
when i find some affordable 4" spring that look black like the OME springs iīll install them instead.
how are the 4" OME springs?

Nothing spectacular. They are just like everything else. They don't offer that extreme superb ride OME is known for.

I'm betting if you installed a tranny temperature gauge as I'm running on mine, that you wouldn't be quite so sure your auto tranny is doing fine with that ratio/tire size mismatch. Auto trannies cope with ratio mismatch problems better than manual trannies do but they do run hotter when doing so, especially on difficult trails.

the OME939/OME946 4" springs donīt offer a good ride like my 2.5" HD OME springs?
are there some better black 4" springs out there?
they have to look like the OME springs.
our association for technical inspection shouldnīt notice that i have some different springs...

Wow, like I stated earlier I have no problems carrying hills in 6th on the highway with minimal downshifting to 5th. Maybe it is just different styles of driving.

Oh I know all that, I was just stating how it performs. If I had the ability to re-gear now I would, but won't since I plan on getting 35's soon and will re-gear then. I also plan on adding an inline cooler to help it out a bit more. I know heat is a killer in auto's but I don't make the trek to Phoenix very often, and when I do it's usually in the evening or night just to make it that much easier on the Jeep.
