what is the stock rear/front differential in a 4x4 ram open or limited slip, if open does anyone know of system similar to aussi lockers that will give me locking axels? also what is the stock gear ratio?

 

correct if wrong, but since you have a 4x4 you should have 3.92's in the rear and the front.

the best way to tell if you have a LSD in the rear is if you do a burn out and you get two skid marks you have LSD. only one is an open. the front is an open. you can get a locker for the front, but you have to change out the diff.

I have the off road package on my truck and I have an LSD electronic locker in the rear. it engages when I go into 4L that I know and might engage in 4H but I doubt it.

 

I have the 3.92's but not the LSD (One tire fire!).

one thing I wondered: When in 4WD (electronicly controlled) the turning radius goes down. Is that from the rears locking, or is it something different. Just have always wondered.

I have 3.55s front and rear. The rear is LSD. You can check the label in your glovebox for your gear ratio and if you have LSD or not. I'm not sure, but I don't think LSD in the front is an option.

 

Front LSD is not offered, but the front electronic locker is standard on the power wagon

 

My 04 4x4 has 3.92s. There should be a tag attached to the diff case by one of the bolts telling you what gears you have.
