Yup, you need the whole shebang, not a cheap thing to do.

I am lucky and can get by with my 3.31's and 33's, but if I use 5th, it
drinks gas. I say with a '4 speed' and forget about OD or 5th and get
23 MPG highway.

Been doing this for 10 years or so in my C7. I don't crawl rocks on the
trails I run so pretty much never even need first low.

If I win the lotto I might think on new gears, but.....

Hi Farrell,
Correct, and correct, the carrier change is at 3.73 on your POS:
http://www.----------.com/dana35c/ and the Dana 44 that was stock on the
original (REAL) Jeep. Your front Dana 30 is at 3.54:

Dang.

Called around and so far just one salvage yard has a 4 banger with the 4.11,
they want $975.00 for the thing. Haven't found Ruby at any of them but I'm
guessing they will be very very $ proud $ of it if I do find one.

My real reason isn't really about gas, the wife drives it 6 blocks to work
and back because it costs to much in gas for me to drive it 50 - 60 miles a
day. The problem is about power. Since I put the 33's on it a couple of
years ago it is really weak in 2 high (does just great off road in 4 low but
4 high is worse than worthless ). On the highway you can't use 5th gear at
all, 5th has 0 power it won't even coast unless your going down hill, 4th
gear is now 5th gear in that you can not accelerate in 4th gear at all and
must drop to 3rd gear if your going up even the slightest uphill grade.
Third gear is the driving gear now, it' does have good power in 3rd but it
runs at about 3+ grand at 65mph in 3rd gear. Taking off from a stop it has
to be babied with lots of clutch and lots of gas or the jeep shakes and the
valves float. I really don't like her driving it even just that short
distance the way it is, it needs more power for pulling out in traffic.

I wonder if it would make any difference to just go up ( numerically) to
whatever the max is on the 3.07 . I would hate to spend the money, even
though I would just do the rear at first, only to find out it really didn't
help at all.

Maybe I can convince her to let me put some 30" tires on it. If I remember
right, that is what it had from the factory and the power was great until I
put the 33"s on it.
