i have a 2.5L 4 cyl 99 jeep tj with dana 30 in front and dana M35 in the rear. i recently changed my gears to 4.88 from 4.11 and i am running 35 x 12.5 R15 BFG's. i am wondering about lockers.. everytime i get stuck the only 2 tires that spin is the ones that is in the air haha. i want 4 tires to spin so i wont get struck. but i do alot of high way driving so i dont want them locked in all the time and i wont lock them until i get stuck. i want a locker where i just press the button and she will lock in all 4's. can someone tell me the pros and cons of this setup and what to use. and if it will arm my little dana 30,m35. and also a rough estimate on a price and a good place to buy them. thanks in advanced
 

Not worth it.....you gonna break the D-35 running 35's. Maybe not now, but eventually. I would step up to a D-44 or 8.8 before spending money on lockers.
 
I agree go with better axles.As far as lockers get a selectable for the front like ARB or OX locker.The rear a good Detroit or lunch box works fine.
 
if i get a D44 or 8.8 do them axles bolt right up or do i have to modify them and can my rims still bolt on or do i have to buy new rims to? and also what kind of gear ratio does the d44 and 8.8 have? ri just changed my gears from 4.11 to 4.88. so this means that was a waste of money? :(
 

as for the gears not really, u could sell the axles to another jeeper that is a roadie and likes to run big tires, on ebay. yeah bud u and me both should have bought a rubi. i need a SYE a d44 front and rear, yoked drive shaft. then ox lockers. lots of $$$$$$$$ and time but hell when im done 5 years from now i'll b happy, and have what i want.
 
I do think 35's are a little big for dana 30 & 35's off road

im gonna stick with my stock axel's and 31's.

but i would like to know how them 4:88 work with 31" tires? good or bad?

Id like to get a set of 4:88 gears for my jeep..
 
it all depends what u call off road.. i dont do no rock climbing i just go out on gravel road and through the trees and bogs and sand and when i get stuck in ditches or snow i want to be able to lock in my 4 tires.. but as for my 35" tires and my 4.88 gears it works wonders.. my 4 banger tops out at 120 km/h. and i treats it hard and the axles still holds up. i gets it stuck in snow and bottoms her out and i rocks her back and forth with snow flying and nothing a broke yet haha. i even done a burn out on pavement with the jeep stuck against a light pole and she still didnt break that was when i wanted to go for lockers i think it is strong enough to hold for what i uses it for
 

ok so just get a rear locker and have some axles on the shelf. an auto locker will work just fine for u i think
 

ARB's are awful pricey though. Powertrax No-Slip works well but is still very streetable. I'm not a fan of front lockers in snow though. A limited-slip like a True-Trac (assuming it's available for that axle, I think it is) or a selectable locker if you want to spend the money, is better for driving on snow.
 
An auto-locker or "lunchbox" only locks up when torque is applied to it. You will notice a slight "smear" or "push" as you go around corners on pavement, but once you have it, a learn to drive with it on pavement, you'll like it. The trick is, if possible, to accelerate, and coast around the corners, then get back on it. They are good and fairly dependable. I have heard good things about Powertrax, but have no experiance with them myself.

Ok i have seen (AUTO-LOCKER) on here a few times WHAT THE @#$# IS THAT NEVER HERD OF IT limited slip yes but not that ..

I think what he is looking for is a open diff then when he needs all four to spin at the same time he can push a button and be LOCKED not just 2 or 3 wheel spinning all four at the same time. yes there $$$$ but you get what you pay for to be locket and know it.

In a 2.5L, 4.88 and 31's are just plain AWESOME! I did the gears before I changed tire sizes, and now I am wishing I could got to 5.13 to keep the same torque. Nothing beats going uphill in 5th gear!

There are many types of lockers; selectable lockers are (typically) open diffs when unlocked, and spools when locked (some are LS when unlocked, though); when driving on the street, it's like not having lockers, and when turned on (either by cable, electronic or air connection), it's like driving a spool (which means if you lock up the front, turning becomes HARD!). Auto Lockers (like Detroit Lockers) lock the differential when torque is applied; these tend to have some drawbacks when it comes to street driving (the detroits have probably the most street issues, but are also the strongest ones off road). Then you have the LS and lunch box lockers, which tend not to be so great offroad (still better than stock, though) or strong as some of the others (LS clutches can wear out, and lunch box lockers can break easier than an ARB or detroit), but have better on-road manners than the more offroad oriented automatic lockers.

In your case, I would probably go with ARB and a D44 from an Izusu Rodeo and a Waggy D44 in front, and gear to 5.35 both axles to have more torque with 35's. But you WILL need to do some mods to run the axles (for starters, you need to take off the old spring perches, weld in new ones, and adjust the brakes to run the rear disc brakes available in that axle, not to mention you need new wheels because these are 5X5.5 instead of 5X4.5).
