Help me pick Gears
Help me pick Gears
My CJ w/ 258 needs a new rear end.
I am going to take this time up upgrade, and only want to do it once. Lift is
nexst on my list But I am unsure how big. Cant decided between 33's and 35's.
What will probably happen is 33's for a cuple of years then 35's But I don't
want to have to re-gear when (and if) I go to 35's.
So if I knew all I would do is 33's I would go with 4.10, But if I ever go to
35's would need 4.56.
My questions:
Am I better off w/ 4.56's and 33's or 4.10's and 35's?
Any suggestions?
If use matters, it's a 5speed. I am doing to for deep mud and light rock
crawling, But I tend to drive this more then my Daly driver unless I am hoping
on the highway, or "need" AC. But I don't want to build this to where I can't
put it on the highway if I need it to.

Re: Help me pick Gears
Hello Evan,
I just went through the same decision. I, too, have the 258 and a 5 speed.
I now have 33s but may one day go with 35s. I decided to go with the 4.56
and have no regrets.

Re: Help me pick Gears
What rpm do you turn on the highway say at 65 mph with that setup?
I might be in need of a new rear end before too long and am curious.
I am turning about 2300 in 4th right now with 3.31's.

Re: Help me pick Gears
Having installed 4.10 for 33" tires several years ago, I knew within a week
or two I should have installed 4.56 instead. 4.10 is ok if all you want to
do is cruise the streets but 4.56 is even better for that. For offroad,
4.10 is too high of a ratio and 4.56 is a far better ratio.
When I went to 35" tires, I jumped to 4.88 with no regrets... 35" tires and
4.88 is a superb all-around ratio for a 5-speed equipped Jeep. 4.56 would
be "ok" for 35" but it's the same deal with 4.10 with 33" tires... both are
too low of a ratio, the next lower ratio raises your engine rpms just enough
to make driving a pleasure instead of a constant 'downshifting' battle. I'd
go for 4.56 for 33" tires if I were doing it again, that is for sure.

Re: Help me pick Gears
My preference is the lower gearing - I'm running 5.13s with 35s and have no
complaints. The 4.0L (and 258) responds well with this combination. Last
time I checked, in 5th she pushes around 2500rpms @ 65-70mph. In a modified
SWB Jeep, I have no desire to go much faster than that anyway. I chose the
5.13s because it gives the flexibility of stepping up to 37s or larger (I
almost went with the 5.38s).
What most agree upon:
4.10 - 4.88 for 33s
4.56 - 5.13 for 35s
4.88 - 5.38 for 37s
