Really liking the LJ! The black chrome powder coat looks great too! It's interesting to see the Jeep/plans before "Savvy" and now after too. I never put it together that your username used to be Provlogear (sp?) as I used to browse/read/search the forums a LOT but didn't post much (hence join date/post count). I remember seeing your name show up quite a bit.
I'm very interested in hearing about the 6spd, 4.88's and 35's.
I have often been wondering if I should switch to 4.56 or 4.88 when I go to 35's.
My Jeep has 3.73's and stock 30" tires made the Jeep way too overgeared. 31" MT were better but 1st gear was still not used much.
Now with 33x10.50 KM2, gears 1-5 are about perfect, although many times I still start out in 2nd as 1st is so low. But 6th drops the RPM just a tad too much on the interstate - basicaly, when I am not using cruise, I use 6th as I can modulate throttle to prepare for hills etc.. but with cruise on, I use 5th. Too often with cruise on in 6th, for going up hills it'll run the throttle wide open just to maintain speed, but in 5th it needs far less throttle input. If this was a 5spd, it'd be geared perfect for 33s, but I'd like to be able to effectively use 6th, and not just use it case its there.
So I've often been wondering if I would prefer 4.56 or 4.88 when it is time for 35's. Part of me says to gear once and go all the way, or I try to think how I would feel with one or the other and if I would have wanted to do it differently.
Basically, I wouldn't mind a 1st gear a tad lower than it is now (already low) but a 6th gear that was ideal to drop the revs into a near perfect highway cruise RPM. I know that simply comparing RPM/speed alone isn't the whole picture, which is why I am on the fence about it. IIRC right now in 6th I am at 2500RPM at 70 and around 2900RPM in 5th, at 70. I usually set the cruise to 65 (in the Jeep) for interstate trips as it is a good speed to get slightly better MPG.
Having compared stock (30" tires) with 1st being useless on the street and 6th a great highway cruise gear, compared to now on 33s, with 1st being very similar to a "normal/car-like" 1st (but still a bit low) though leaving 6th as useable, but 5th preferred for interstate driving - if it came between recreating those two situations on 35s between 4.56 and 4.88, I would choose taking off in 2nd most the time, with a very useable 6th and a 1st for when ever a much slower speed was required.
I know with the 5spd, 4.88 are reccomended, but this is the 3rd opinion from a reputable source that I have read saying 4.88 and 35s on the 6spd are too low for street driving.
