I was wondering what everyones thoughts are. I am running 33" tires with stock gears. I am wanting to change gears but can't make up my mind. I drive it alot on the street (kind of a daily driver somtimes) and I wheel it often also. What are your thoughts and how does yours perform?

i got the same setup and im going with 4.56's

I'd have to say 4.56's, I would imagine that 4.88's are just a bit to steep for any highway driving.

4.56s unless lit is strictly a trail rig.

4.88's especially if its an auto

not too steep at all

how are they on the hwy and what kind of MPG should a guy expect?

i have run 5.38's with 35's (lower than 4.88 and 33's) and love it

highway cruising at 65 i get low 20's mpg.

Well im getting 33's in the spring (31's now on 3.55s) and I've pretty much decided on 4.10s actually, might be a little high, but probably about the same as what I have now on my stock gears, and that isn't too bad. Most people I have seen though go with 4.56's though.

4.88s.

i have 4.56 i wish i had that little extra pep with my tired motor.

if your not road driving to far throw the 4.88s on. what would make you happier? To wheel or not to wheel that is the question!

4.88's would be a sweet setup. Definitely a bit steeper than 4.56's, but probably well worth the power gains.

My concern would be with the size of the pinion gear though, it's mighty small in a D30 with 4.88s.

so is a dana44 5.38 gear

but i have broken about 8 shafts, i driveshaft a detroit locker, original pinion

This is true, anything is break-able.

I believe 4.56 should put you back to about stock gearing with 33's.

The only way I'd say go 4.88's is IF there is a chance of 35's in your near future. Other wise get the 4.56's or you'll hate your self later.
