Running 33"s

So I wanna run some 33's on my 97 TJ 4.0L on my stock Dana 30's with 3.07 gearing. Has anyone done this and how bad would it be to do it like this?

Also I found this...
4:10 Gears and Limited Slip Diff for Chrys. 9.25

on craigslist. could i swap this? It's a chrys. 9.25 diff with limited slip. would this work to run 33's.

To fit these 33's im looking to get the rough country 3.25 suspension lift kit. Does anyone run on this and do you need anything more than what comes with the kit to run a safe setup with out death wobble?

I run 33s with 3.07 gears, not the best but it works. Don't waste your time on those gears, if you really feel like you want to re gear go 4.56 or 4.88. I would wait until you can afford a d44 or 8.8 because it's only a matter of time before you want 35s.

FYI, D30 is the front, either d35 or d44 in the back. You probably have d35 unless you have rubicon. That's why if you regear now, you will only have to spend more money in the future to re gear the next axle. Your better off using the money you would use to reagear and save up a bit more for a custom built 8.8 at East Cost Gear Supply.

1. Flesh out your profile. "Stock" for everything doesn't say much.

2. 33's + 3.07 gearing = no acceleration and bad gas mileage, in general.

3. The 9.25 is a strong unit, but parts are more expensive, you're limited to 4.56's (don't quote me on that, actually) and I think It's a C-clip axle, which is not cool. But yeah, you can swap anything...just not sure why you would, in this case. And you to regear the front as well, you know.

4. Yes, you need more than just the kit...basically, you need all the common modifications to lift a TJ 4"...a quick search will turn up the particulars.
If it's worth doing, then it's worth overdoing.

I did a 2.5 OME and got adjustable front and rear trackbars as well as brown dog motor mounts, jks rear adjustable links and an antirock up front.
