Cruising RPMs with the 4.56s is similar to stock gearing with stock tires.
What's not to like?

I can't see why I'd want to switch to 4.56 yet when I haven't found a spot where I couldn't get up so far.
More control. Going downhill, you'll need the brakes less, which means less slipping and sliding. Going uphill, less throttle is needed to climb over an obstacle, making it easier to back out once you clear it and giving you more control as you climb.

Re: Another Gearing Thread.

Ok, now I have to throw in a monkey wrench into my own gearing thread. I was leaning towards 4:88's.

But, after much research, I picked up a 241J (4:1) transfer case out of an 03 TJ. So now, given the ratio on the 241, would 4:56's be more appropriate?

I was worried that 4:88's might be more revs on the freeway, but I was willing to live with that.

But now I'm thinking 4:56's might be more appropriate, it will be a little less revs on the freeway, and still have more crawl ratio that I was looking for.

Any thoughts? Thanks.

Re: Another Gearing Thread.

Definitely something you should consider. I run 4.10's with 33's and a 4:1 T-case,it has always(20yrs) ran great towing my trailer thru the mountains and crawling I have gotten under the jeep when in gear on the trail as it moves so slow. Now with my stroker I could easily pull with some 3.73's!

Re: Another Gearing Thread.

If you go that route, you might consider getting an override switch for the AW4. Depending on the type of trails you're on, 1st can be kinda slow in 4L, and 3rd can be a little fast. 2nd is the sweet spot for most of my trail runs, especially in a convoy with rigs closer to stock gearing.

I was thinking of doing just that, as well. I'm glad you brought it up. Are you thinking something like from Montana Fab? Or something else?

Re: Another Gearing Thread.

More important, get the 2-low kit for the transfer case, it will pay off instantly as I rarely use 4wd anymore.

I know you have talked about this modification before, but can you explain again the advantages of this?

It allows driving in low range in 2WD, many times in steep situations, low gears are wanted when the lack of traction isn't a problem .
If nothing else, it makes driving in traffic jams easier.

Re: Another Gearing Thread.

The main benefit to me is because I'm locked front/back so when in 2lo the steering doesn't fight you, plus I get better mileage too. It will shift on-the-fly to 4lo so if and when it's needed it's easy to do.

Re: Another Gearing Thread.

Makes sense, thanks for the explanations. I'll look in to it. I'm going to have the transfer case gone through before I install it, so getting a 2 low kit should be easy.

Either MontanaFab's, or NickInTime's that he just released, which is completely plug-and-play with no wire cutting or splicing. https://nickintimedesign.com/product...fter-jr-v1-97/
