How do I know my stock ring and pinion and do I need front carrier my jeep Sahara 2010 unlimited 4drs

Take it to the dealer and have them print a build sheet based on your vin, request one from chrysler.com with your vin, crack the cover and look for markings, rotate a tire and count how many times it rotates in relation to the driveshaft.

Just a few ways.

To your carrier- it depends on what gears you had and what locker you decide to add (if any- selectable, TT, autolocker, lunchbox, etc.)

I put in the truetrac in the front for my carrier so I could go to the deeper gears. I wanted something better than the stock open carrier, without going to a full blown locker.dollar for dollar better than stock.You can run it in the rear to if wanted..Just a better limited slip unit..

I used USA Standard 4.56 gears and they are working great.
