THe answers to your questions:can i get a front locker for my fj? if so can i have a-trac on when i have just the front locker on?,and not the rear? can you have a-trac on when you have rear diff on? thanks:rocker:
I have the ARB front locker. You have to drop your gearing to at least 456. If you get locked up front and rear, you'll never use A-trac again! I know a bunch of people are going to hit me up and argue this point and tell me how great A Trac is because you can still turn etc....etc, but I've run both in tons of situations and my locker set up crushes A Trac every time. You can have my A trac.
Incorrect. ARB has two options for front lockers for the FJ. I think 3:90 is the gear ratio threshold that decides which one you need. I installed an ARB front locker with the stock gearing on my auto (3:73 is the OEM ratio I think), but when I re-geared (to 4:10's) I had to purchase the other ARB unit, which also works with the 4:56 and 4:88 gears as well.You have to drop your gearing to at least 456
it stands for FJ Cruiserwhat is a fjc? iv only herd of an fj...whats the c?>
The black cherry is the older color that is kind of a dark red. The newer brick red color is a brighter red than the older one. The newer one actually looks red, the black cherry looks black until you see it in the sun or up close.o duh...stupid me...hahaha ok some people call it black chery or is it brick red>?

I can't argue one way or the other cause I'm not locked up front, but. Have you tried to run both at the same time?I have the ARB front locker. You have to drop your gearing to at least 456.

I agree with your first paragraph....but the last one, I too am confused about.If you are locked up front and not in the rear and have atrack on, applying brakes to the front and not the the rear will cause axles to break. End of story.

How?
If the front is locked and the rear is not and you have atrack on.....the atrack will simply not actuate the front brake calipers since no difference in wheel speed will occur b/c of the ARB. Therefore, the only thing the atrac will be controlling is the rear axle and it will function as normal (I'd assume) braking whichever rear wheel is spinning. It's just like the current system of having the rear end locked with the Atrack on.....and that doesn't break axles. Is this incorrect?
*******************************************************
It's important to note that if any "automatic" locking diff like a Detroit or Lockright or Aussie becomes available for the FJC front end....it will have very slightly different amounts of wheel speed by the very design of the auto locker....so they should be avoided if use with the atrac system in conjunction with the front locker is intended. Of course that also depends upon how many tire revolutions it takes for atrac to engage, but I digress. As someone already mentioned in this thread, once you have f/r lockers, there's almost zero reason to ever use Atrac anyway.
