i have 3.73s in my jeep now. compared to my old jeep with 3.07s, it is a world of difference

I just took a trip to the mountains in NC from the Florida flatlands with the 3.73 and 33's.

Overall, I was fairly pleased with the performance. In Florida, there seems to be only a slight loss of power in accelerating to and maintaining highway speeds.

In the mountains, there was the expected loss of power and required down-shifting. In fact, just maintaining highways speeds up gradient was much more of a challenge.

I couldn't imagine doing it with the 3.07.

I think you will notice a significant difference.

You will notice a large difference... 3.07 to 3.73 is a 20% difference. If you have an auto without overdrive, it's pretty much ideal with 33s.

Well worth $200, I just paid $200 for a D30 housing built with gears (also came with an R&P w/carrier for the 44), and considered it a bargain...

Is it possible to find out what you have without opening the casing?

There is a tag bolted onto both axle differential covers that has the ratio embossed into it.

I would do that swap right now if I could find that kind of deal, and I'm only running 31s. Like mentioned, there is a big difference between 3.07 and 3.73.
