3.54 to 4.88

So I am thinking of switching gears to 4.88. I still have the D35 rear axle, i will eventually switch to a ford 8.8. I don't have the money to do everything right now though. Is it worth it to go the 4.88 and then when I get the new axle just gear it to the 4.88 also? or should I just hold out until I get the axle and do it all at once?

by the way I am new and i tried to look for other threads but didn't have much luck. I don't care much for the search function on the forum. Thanks

33X12.50 I doubt I will ever go bigger I like the 33s a lot. I only do mild wheeling and it is a daily driver

well, with 3.54 gears stock, i assume that you have a 4.0L and a 5 spd. if you jump the whole way up to 4.88 while running 33's i would think that the jeep will be a little gear bound. what i mean by that is it will be limited on the top end mph wise.
I have an 87 with a 4.2L and a 5spd, and i am running 4.56 gears and 35's. my top end is around 70. not that i would want to go that fast, cause its not a daily driver and it never sees any interstate running.
IMO i think that you dont want to go quite so deep in the gear ratio, if you dont ever plan on going taller than the 33's. as far as waiting for the 8.8, thats a good choice, but i ran 33's on the dana 35 for almost 4 yrs before switching to the 8.8 rear. never had a bit of trouble with it, as long as i kept a level head when i was out playing.

4.88 is really steep for only running 33s. 4.10s are suffice for your set up. I'm running 33s with 4.10s and top out at a little over 70.

I would go straight to the 8.8 at that point and regear the front. It will probably be the same price as regearing both stock axles.

I guess I will just stick with my current gears for now and find an 8.8 that has the 4.10 or better and then regear the front to match. Thanks everybody.
