Gearing

Thinking of going with 4:56 gears with aussie lockers front and rear. Will be running 32 inch bfg M/T. Will this be to much gearing?

Thank you, Will the 4:10s be enough?

it is the best you can do, better then not running 4.10s with 32s

4.10 would be great, but for re-gearing you are talking about $1200, for the gears, master overhaul kits and gear oil and labor

the aussie locker wont work in the D30a, you can only get the Aussie for the C8.25 for the D30a you only have two choices, DTT and ARB

only the KK Liberty can re-gear to 4.56 :evil:

They don't make 4.56's for KJ front diff's - 4.10 is it and you have to buy those from Mopar.

can I say it as well, :roll:

4.10s is the lowest you can go in the front
now the rear thats a different story :wink:

Does anyone have the part # for the 4.10 gears F and R from mopar?

Can I do DTT and or ARB front and rear?

You can do a DTT front & ARB rear. You could run a DTT/Aussie ( or powertrax no slip) combo if you wanted or a DTT/Detroit Locker combo or a.... there are many options.

Also, there are other sources for the gears if you look around. Getting them ordered may be an issue, but they are out there.

Here is one source:

Good luck.

add the price of a compressor to any combo running an ARB....

VVVVVVVVV

FRONT:
Detroit TrueTrac-$400
ARB-$800

REAR:
Detroit TrueTrac-$500
Detroit Locker-$550
ARB-$800
Aussie/ Powertrax-$300/ $460

you would just to pick and choose and it will work, and those prices are about right, the only prices Im not sure about are the ARB b/c I cant afford them so I havent looked into them

One of the wiser founding fathers of LOST once posted his best to use front and rear combinations that he thought would work best together
F= Front
R=Rear
1. ARB (F) ARB (R)
2. DTT (F) ARB (R)
3.ARB (F) DTT (R)
4. DTT (F) DTT (R)
5. DTT (F) Powertrax (R)

may give you something to consider :wink:

what about the Detroit Locker?? DTT (F) DL (R)

You will also want to find out if you have the trac-lok rear diff. If you do you will not be able to use the aussie locker. Also, It might not be wise to use an automatic locker in the front of a daily driver. That would be dangerous. Remember, you have to steer your vehicle from the front. If both front wheels become locked at the same speed it will make it very difficult to turn and in an emergency situation that could be costly. If you want a locker in the front use a selectable like arb.

Next summer if i get to do the locker thing i'd like to do DTT front with a DL or arb rear. i'd like an arb (more versatile) but to save some coin the DL works too.
