Icon5 What ratio?

Well, I tore the front diff out of my truck. Ring and pinion gears are completely gone. So, instead of just replacing them with the stock 3.08:1 gear ratio, I was thinking about replacing both ring and pinions to something a little taller, like a 4.56:1 or something. My truck is a 1993 4.0L Ext.Cab, and I plan on running 33's on my polished 15's that I will post in another thread once they're finished. So, back to my question: Will going from a 3.08:1 to a 4.56:1 ratio be overkill just for 33's?

*My current tire size is 235/75/15, going to 33x12.50x15*



Thanks in advance

He can't get 4.30's for the front diff.

I would go 4.10's if it was me. You can probably find a comlete diff and rear end in the junkyard for less that it would be to install the 4.56's.

One day I would indeed love to go to 35's, and I can get gears at a wicked good price so it's no big deal to me.

But you seriosly had 3.08's? wow did that come factory?

If you are using it as a DD, then get 4.10's but if it is a full time wheeler, then get 4.56's, but even those will be pretty tall. OHV's have alot of low end torque, you can get away with a numericly lower gear ratio.

If it was mine, I would find some cheap 4.10's and then save up for the 4.56's and install them when you get 35's.

According to the local Ford dealership, I indeed have 3.08's. I walked in, gave them my VIN, and they pulled up the vehicle history from their archives.

Mostly, my Ranger will be a MallCrawler, with the occasional trip off-road. I will clear 33's once it's lifted, that much is for sure. 35's is still a coin toss. I'm not sure I want to spend the money required on a truck that is as old as mine.

So, if you're suggesting that 4.10's are the proper ratio to go with, what company should I get them from?
-Yukon?
-Precision Gear?
-Genuine Gear?
-Richmond?
-or other?

To be honest, I have no mechanical know-how at all. I just drive, and put fuel in the tank as needed. And that's why I turn to forums like this. I know someone out there has been in my exact position before, that's why I ask.

4.10s because I am guessing this is your DD? 4.0 and 4.10s should spin 33s just fine.
