gearing/tires/lockers

Hi guys, my cj currently has 3:31 gears with the factory limited slip, my question is this...i want to add lockers front, and rear.....and, eventually i want to run 33's (currently 31/10/50's), so, my first question is are the 3:31 adequate for the 31's i currently run? ie: would it be worth it to add the lockers now, or am i better off just waiting till i can regear, and then add the lockers.....just put new 31's on my cj, so, it'll be quite awhile before i'd go to the 33's.....Thanks in advance for your responses
Cory

Are you talking about lunchbox lockers or full-case lockers? Personally I would regear at the same time as adding lockers to keep from messing with them twice if you are going with detroits or ARBs. The lunchbox lockers could be installed now with you doing the gears later if necessary.

Bro I'm in that situation right now. I recently purchased 33's and I'm in overdrive hell. At first I was going to just regear, but when I started readin' up on lockers and all I realized that if I was going to regear I might as well get the lockers too!

I priced around and recently got a quote of $2500 out the door from 4 Wheel Parts Wholesalers which I'm pretty sure at this point that I'm going to go with. It includes the following:

- Regear to 4:56 both Axles (I'm running a D30 & AMC20)
- Bearings & Seals for regearing
- ARB Lockers Front & Rear
- Running air lines from both lockers to my existing OBA
- Installing a switch in my dash for the Lockers.

3:31 is good for 31s if you have the 6 or 8 cylinder. Same thing as said about lockers. If you're gonna run a lunchbox style, do it now. It's a simple do it yourself install. Strongest one of these seems to be the lockrite. If you're gonna use a full case locker it's cheapest to do the gears and lockers at the same time as you'll have to have the gears setup. Plus for the front d30, if you buy a full case locker for the 3:31s, you can't use it with lower than 3.55 gears when you change them out.

A good rule of thumb on gears is .12 x tire height(in inches).
31 in tire x .12=3.72 (3.73gears)
33 in tire x .12=3.96
If you are going with a good locker, regear now.
Do it once right

Thats a pretty good formula. I have never seen that before.
